PRACE jesenska šola 2013 - Industrijske simulacije na superračunalnikih

Fakulteta za strojništvo Univerze v Ljubljani je kot koordinator združenja PRACE za Slovenijo -- Partnerstvo za napredno računalništvo v Evropi (Partnership for Advanced Computing in Europe) v zadnjem tednu septembra 2013 organizirala enotedenski tečaj industrijsko naravnanih simulacij z uporabo visokozmogljivih računskih sestavov (HPC). PRACE jesenska šola je komunicirala ter diskutirala prolematiko in perspektive HPC za industrijske aplikacije, ki potrebujejo oceno zmogljivosti in zasnovo izdelkov s poudarkom na področju mehanike struktur (SM), dinamike fluidov (CFD in BIO-CFD) in elektromagnetike (EM).

PRACE združuje vodilne nacionalne centre za superračunalništvo članic Evropske unije in povezanih držav. Z vstopom v povezavo v lanskem letu je Fakulteta za strojništvo UL dobila možnosti širšega sodelovanja na implementacijskih projektih PRACE-3IP v okviru izobraževanj in organi zaciji dogodkov, kot je Jesenska šola industrijsko orientiranih simulacij na superračunalnikih (HPC). Moto jesenske šole je bil prikaz orodij za simulacije, ki jih lahko industrijski uporabniki uporabljajo pri snovanju in optimizaciji izdelkov. Simulacijska orodja, ki so bila prikazana, so že večkrat preizkušena na konkretnih industrijskih problemih. HPC pa v teh primerih prispeva k doseganju relevantnih simulacijskih rezultatov kot tudi k iskanju optimalnih rešitev v danem času. Vse preveč krat se namreč izkaže, da brez HPC lahko obravnavamo le poenosta- vljene »šolske« modele, za »prave« industrijske probleme pa običajno zmanjka človeških in računskih virov. Ta problematika je bila tudi vodilo programskega komiteja, da pokaže uporabnikom iz industrije, kakšne so zmožnosti HPC na področju strojništva in elektrotehnike. S pomočjo povezave PRACE je tako bilo možno povabiti strokovnjake, ki imajo večletne izkušnje s področja simulacij in orodja vsakodnevno uporabljajo ali celo sodelujejo pri njihovem razvoju. Drugo vodilo jesenske šole je bilo, ne samo prikaz orodij za simulacije, ampak pripraviti tečaje z uporabo teh orodij na superračunalniku HPCFS. Tečaji »hands on«, čeprav največkrat prekratki, so najboljši način, da se pridobi hitro razumevanje postopkov, ki so potrebni za simulacije z uporabo HPC. Fakulteta za strojništvo ima večletne izkušnje s programsko opremo ANSYS Multiphysics, ki je tudi poglavitno simulacijsko orodje na HPCFS. Povezava tega sklopa orodij s sorodnimi orodji in rešitvami se je pokazala kot logična orientacija pri izboru za jesensko šolo PRACE, saj so vabljeni predavatelji prinesli s seboj tudi izkušnje, uporabljene na konkretnih industrijskih projektih s to programsko opremo. Poleg tega pa je programski odbor želel prikazati tudi nekatera povsem specializirana in ne dovolj razširjena simulacijska orodja, ki se kažejo kot napredek na področju simulacij s HPC.

Poster session

Ciljna publika jesenske šole so posledično bili uporabniki iz industrije in s tem tudi povezava univerze in slovenske industrije, ki HPC kot orodje še vse premalo uporablja pri svojem razvoju. Čeprav je bila jesenska šola mednarodno naravnana, se je pri sno- vanju programa gledalo tudi na skladnost s potrebami slovenske industrije in prav zaradi tega je bilo vključeno tudi področje elektromagnetike. Skupaj 68 udeležencev, od tega 11 tujih, je v zadnjem tednu septembra tako dobilo dostop do superračunalnika HPCFS, na katerem so lahko tudi praktično preiz- kusili delovanje posameznih pro- gramov. Zaradi širokega spektra in specifičnega interesa udeležencev je bilo mogoče omejene kapacitete računalniških učilnic na FS ustrezno razporediti in omogočiti prav vsem dostop do HPCFS. V primeru razčličnih interesov pa tudi paralelno izvedbo v dveh računalniških učilnicah. Tako so se udeleženci enakomerno porazdelili preko celotnega tedna in večjih težav zaradi omejenih virov ni bilo.

Tečaje na programski opremi ANSYS, optiSLang, AVBP, elsA, RBF-morph je vodilo 11 tujih predavateljev (CADFEM, SimTeC, CERFACS, ONERA, CINECA, rbf-morph, Univerza Rim Tor Vegata, Aveiro in New Brunswick) s področja mehanike struktur (SM), dinamike fluidov (CFD in BIO-CFD) in elektromagnetike (EM [HFSS in Maxwell]). Pred pričetkom šole je bil organiziran tudi osnovni tečaj uporabe HPCFS, na katerem so bile prikazane osnove za uporabo superračunalnika kot tudi splošen pregled s primeri razvoja programov na HPC s programskima modeloma MPI in OpenMP. Da bi bolje povezali udeležence šole, je bila organizirana tudi predstavitev s posterji, na kateri so posamezniki prikazali svoje dosedanje delo v povezavi s simulacijami.

Prof. A. C. M. Sousa je zaključil svoje uvodno predavanje o perspektivah računske dinamike fluidov (CFD) in HPC z ugotovitvijo, da primerjava eksperimentalnih rezultatov in simulacij na nekaterih področjih, kot je npr izgorevanje, še vedno predstavlja velike izzive tako v modeliranju kot v potrebnih računskih zmogljivostih. Praktične izkušnje s področja strukturne mehanike so predstavili predstavniki podjetja CADFEM, ki so tudi vodilni evropski kompetenčni center ANSYS za FEM-analize. 

Na HPCFS je bilo tako demonstrirano orodje OptiSLang v povezavi z ANSYS Workbench, ki omogoča multidisciplinarno optimizacijo, študije občutljivosti in zanesljivosti ter robustno optimizacijo konstrukcij. Prav tu pride zmogljivost HPC do izraza, saj lahko vzporedno obravnavamo več variant rešitev. Uporabniki iz elektroindustrije so preizkusili oddaljeno izračunavanje njihovih visokofrekvenčnih anten, modeliranih v HFSS, in elektromagnetih naprav z Maxwell tako, da so preko vmesnika RSM pošiljali svoje posle na HPCFS. Področje CFD je dokaj široka veja fizike fluidov, zato je bila na šoli obravnavana tudi tematika biotokov in konstruiranje jader, ki so v domeni italijanskega superračunalniškega centra CINECA. Hemodinamika ožilja na tečaju BIO-CFD, ki je bila demonstrirana neposredno iz superračunalniškega centra CINECA v Milanu na HPCFS z oddaljenim namizjem NX.Prav tako smo iz Italije dobili možnost vpogleda v program RBF-Morph, s katerim je možno hitro modificirati mrežo računskega območja, in s tem skrajšati čas in izboljšati mreženje. Ker je »morfanje« mrež aktualna tematika raziskav, z univerzo Tor Vergata iz Rima že sodeluje podjetje Pipistrel iz Ajdovščine. FS pa bo sodelovala v novem projektu MorphLab z eksperimenti na HPCFS. Prav lasten razvoj simulacijskih kod je ključen za obvladovanje ključnih podrobnostih, ki jih ONERA – Le centre français de recherche aérospatiale in CERFACS – European Centre for Research and Advanced Training in Scientific Computation vključuje v kodah elsA in AVBP za ključne uporabnike, kot sta Airbus in Safran. Simulacije izgorevanja v turbini smo v razširjenem tečaju lahko preizkusili na kodi elsA. elsAZa splošne namene CFD pa je bil organiziran celodnevni tečaj s programom Fluent, ki ga je predstavilo podjetje SimTec iz Grčije in Slovenije.

Koordinator PRACE za Slovenijo prof. dr. Jožef Duhovnik ocenjuje, da je članstvo v tej povezavi veliko priznanje fakultetnim naporom na področju HPC-računalništva, vendar obenem velik izziv: »Upravičiti moramo zaupanje države in evropskih partnerjev, ne le v razvojnotehnološkem smislu, ampak predvsem tudi s spodbujanjem in omogočanjem uporabe superračunalništva v izobraževanju in industriji. Vendar naloga fakultete, kot nacionalnega partnerja, ni le, da sama uporablja to izjemno orodje, ampak da obenem spodbuja uporabo superračunalništva v industriji, ki na seznamu 500 najzmogljivejših superračunalnikov zavzema več kot polovico HPC-sistemov. PRACE-jeva jesenska šola simulacij je pokazala, da interes slovenske industrije za HPC obstaja! « Drugi pomemben steber delovanja PRACE je spodbujanje dijakov in študentov, da razvijajo kompetence v superračunalniškem okolju. Poleti 2013 je tako FS gostila mlajše podiplomske študente v sklopu mednarodnega projekta izmenjave PRACE Summer of HPC, ki so se pod vodstvom mentorjev FS seznanili z uporabo HPC v znanosti in tehniki. Kot rezultat 8-tedenskega dela pa so nastale privlačne in uporabne vizualizacije. FS si bo še naprej prizadevala nadgrajevati stopnjo znanja in kompetenc s področja HPC in delovala kot povezovalni člen pri širši uporabi HPC-orodij za slovensko industrijo.

Poziv in obvestila udeležencem jesenske šole

Fakulteta za strojništvo, kot koordinator združenja PRACE za Slovenijo, v zadnjem tednu septembra 2013 organizira enotedenski tečaj industrijsko naravnanih simulacij z uporabo visokozmogljivih računskih sestavov (HPC). Tečaje na programski opremi ANSYS, optiSLang, AVBP, elsA, (rbf-morph)™ bo vodilo 11 tujih predavateljev (CADFEM, SimTeC, CERFACS, ONERA, CINECA, rbf-morph, Univerza Rim »Tor Vegata«, Aveiro in New Brunswick) s področja mehanike struktur (SM), dinamike fluidov (CFD in BIO-CFD) in elektromagnetike (EM [HFSS in Maxwell]). Kotizacije ni! Prijave so možne do zapolnitve sedežev.

Tečaj je namenjen industrijskim uporabnikom doma in v tujini. Predvideno število vseh udeležencev je okoli 50. Po dosedanjih izkušnjah pričakujemo vsaj polovico tujih udeležencev. Domači uporabniki ne potrebujejo nastanitve v hotelih. Na posameznih predstavitvah in tečajih se lahko zgodi, da ne bodo polno zasedene. Domači udeleženci naj se prijavijo ter podrobno predstavijo interes udeležbe. Glede na prijavljeni razpored in temeljno zahtevo, da mora vsak udeleženec imeti popoln dostop do superračunalnika, bomo pripravili dinamično planiranje kapacitet, še posebej v delu, kjer bo interes večji. Možne so torej tudi prijave za samo določene tečaje vendar bodo imeli prednost tisti, ki se bodo udeležili vseh predavanj in bodo svoje delo predstavili s posterjem na začetku šole. Obveščanje bo na spletni strani http://hpc.fs.uni-lj.si/project/as13.  Za dodatna pojasnila pokličite 01 4771716 ali pošljite elektronsko pošto na mateja.maffi@lecad.fs.uni-lj.si.

Podrobne informacije in prijave so na spletni strani  http://events.prace-ri.eu/event/as13

Dostopno gradivo: zloženka in poster.

Odgovori na vprašanja:

Splošna predavanja bodo v večji predavalnici, kjer boste lahko tudi kaj vprašali. Praktični del (hands-on) bodo vaje za računalnikom na našem HPC s sledenjem predavatelja. Tudi tam bo čas za diskusijo na koncu. Posterji bodo priložnost za komunikacijo med uzdeleženci in nekaterimi predavatelji, ki bodo že v ponedeljek tam, pa tudi kasneje med pavzami oz kosilom. Se pravi, da bo čas vsaj par dni za diskusijo o problemih pred posterji.
> Pozdravljeni.

Bi mi lahko prosim povedali, kako bodo ta predavanja izgledala? Ali iz podjetja prinesemo konkretne probleme, ki bodo delno predstavljeni na plakatu? Pri prijavi sem se odločil, da ne bom prinesel plakata, vendar sem si po pogovoru z direktorjem premislil. Ali izrišemo del konstrukcije, ki jo potem v v do ločenem formatu prinesemo tja?

Ker niste dobro izpolnili prijave in napisali kej želite biti (samo EM) in ker je na EM že zmanjkalo sedežev, se bomo verjetno, po pregledu naslednji teden, odločili in najverjetneje predlagali, da EM sedita po dva za enim zaslonom ali pa da uporabimo dve manjši predavalnici za HFSS in Maxwell ter hands-on ponovimo. Vseh osebnih računalnikov imamo sicer dovolj, je pa število omejeno z velikostjo učilnice. Vsak udeleženec bo dobil dostop do superračunalnika, za kar potrebujemo podroben pregled in pripravo oz koordinacijo enega samega vira - velikost učilnice in superračunalnika ter "workstation"-ov. Kako bo to potekalo je še v dogovoru med paralelnimi sejami. EM in CFD sta po računski zahtevnosti dokaj različna.

FAQ:

I am interested in Structural Mechanics and Computational Fluid Dynamics. On Thursday and on Friday I would like to attend lectures that meet my field of interest: CFD: Express Introductory Training in Fluent and RBF: Morph hands on. As I have no experience in ANSYS . I would like to attend all other lectures but I won't need the computer I just want to see everything what ansys can offer.

So you would like to be reserve for ANSYS hands-ons. Mateja will update this in the table. Lectures will be quite new for all as no direct knowledge on special software will be needed. If you will be able to repeat is, of course, up to  you. Please note that some trainings will be fully booked with litte place for additional seats.

Due to large interest in elsA and AVBP by ONERA - Le centre français de recherche aérospatiale and CERFACS - European Centre for Research and Advanced Training in Scientific Computation we rescheduled and extended this tutorials (from 3h30' to 5 hours hands-on) by including small turbine case. This means some time changes in Friday's sessions that are now scheduled in sequence. In the morning there will be shorter lectures from CERFACS and then it follows RBF-Morph until lunch. In the afternoon elsA and AVBP hands-on are carried out with breaks at lecturer's discretion. See timetable for details!

Accepted registrants list - status September 20th 2013:

Please note that there is technical limitation on seats arrangements for computing classrooms only in a table below. For general presentations in lecture hall VI/2 there is no such limitation! We will be updating table below in the next weeks until we close registrations. Please notify us if you will not be present at come time so that we can uncheck you and have place for somebody else in computing room. The largest II/5 has 44 seats.

Hands on and lectutes attendande legend:

PRACE Autumn School 2013 - Industry Oriented HPC Simulations

from to (CET)
at University of Ljubljana ( Lecture room IV/2 and computing rooms II/5, III/1, N17 )

Faculty of Mechanical Engineering Aškerčeva 6 1000 Ljubljana Slovenia
Resolving Industrial Engineering Applications with HPC by ANSYS, optiSLang, AVBP, elsA, RBF morph, etc.
In today's competitive product development, high performance computing (HPC) delivers outstanding value and investment return. Parallel computing increases understanding, productivity and accuracy of the simulation - a faster turnaround, reduced costs, systematic design variations and more complex models.
The PRACE Autumn School communicates and discusses issues and perspectives of HPC targeting industrial applications arising from evaluation performance and/or design of products, e.g. equipment and processes, with a particular emphasis on the automotive, aerospace, and energy fields. The PRACE Autumn School places priority on algorithms, simulation strategies, and programming techniques for complex fluid flow simulations, structural mechanics and electro-magnetics which usually have coupled multiphysics requiring intensive use of HPC resources. In case of expertise and software availability, there will be presentations of other issues, e.g. robustness and performance analysis, a brief introduction to pre- and post-processing techniques, e.g. CAD integration, mesh generation and visualization are presented.
The PRACE Autumn School targets at (40-50) experienced industrial users and some academics. Case studies and hands-on tutorials will be carried on the ULFME cluster. The tutorials will be held in parallel and in subsequent sessions, depending on the applicants' interest indicated in the registration questionnaire.

Due to large interest in elsA and AVBP by ONERA - Le centre français de recherche aérospatiale and CERFACS - European Centre for Research and Advanced Training in Scientific Computation we are considering to extend this tutorials (from 3h30' to 5 hours hands-on) by including small turbine case. This means some time changes in Friday's session with little possibilities for sequential with RBF-Morph tutorials.

    • 09:00 - 18:30 Computational Fluid Dynamics: Custom CFD codes and plugins
      Location: University of Ljubljana, Slovenia ( Computing rooms III/1, N17 )
      • 09:00 High Performance Computing of gas turbine flows: current and future trends 1h' ( Lecture hall IV/2 )

          Nicolas Gourdain presents elsA for aerodynamics used by many by industrial partners such as Airbus, SAFRAN, etc. and AVBP for combustion, used by SAFRAN, IFP, etc. 

        The use of Computational Fluid Dynamics (CFD) is mandatory today both for scientific investigation of complex flows and industrial design of gas turbines and aircraft. Further improvement and optimization of such systems currently present one of the most formidable challenges in modern engineering research due to the very stringent requirements for efficiency, pollutant emissions, reliability and safety. Efficient numerical tools coupled with high performance computers, have become a key element of the design process in the fields of energy supply and transportation. However flow phenomena that occur in complex systems such as gas turbines and aircrafts are still not understood mainly because of the models that are needed. In fact, most CFD predictions as found today in industry focus on a reduced or simplified version of the real system (such as a periodic sector) and are usually solved with a steady-state assumption. This course discusses how to overcome such barriers and how this challenges can be addressed by developing flow solvers running on high-end computing platforms, using concurrently thousands of computing cores. Parallel strategies used by modern flow solvers are presented with particular emphases on mesh-partitioning, load balancing and communication.

        Speaker: Dr. Nicolas Gourdain (CERFACS)
      • 10:00 RBF morph theory and applications case-history 45' ( Lecture room VI/2 )

          An overview about mesh morphing and its benefits will be given with a specific focus on Radial Basis Functions (RBF) methods and the industrial tool RBF Morph, currently available as an add-on for the CFD solver ANSYS Fluent.

        Standard applications of mesh morphing will be first explained; the tool is here used as an effective way to makes the original CFD model parametric with respect to the shape. Details on how such parametric models can be introduced in typical industrial workflow (shape or set-up optimization) will be given including CAD connection (STL targets and back to CAD) and flow sculpting (using adjoint solver of Fluent).
        Advanced applications will be covered as well including: fluid structure interaction using 2-ways FSI and modal superposition, ice/snow accretion modeling, transient morphing with desired time histories.

        Speaker: Prof. Marco Evangelos Biancolini ("Tor Vergata" University of Rome)
      • 10:45 Coffe break 15'
      • 11:00 RBF morph hands-on 1h30'

          The first session will cover basic exercises to set-up shape modifications on simple geometries (a cube immersed in a wind tunnel and a straight pipe). A step by step set-up will be demonstrated to gain confidence with the GUI of RBF Morph (set-up stage). An advanced session addressed to industrial meshes and complex set-up will follow. Pre computed set-up will be available so that the students can deepen their knowledge about advanced feature of RBF Morph for check trouble shooting the set-up (preview, mesh quality).

        Speaker: Prof. Marco Evangelos BIANCOLINI ("Tor Vergata" University of Rome)
      • 12:30 Lunch break 1h'
      • 13:30 Multi-block structured code (elsA) and an unstructured code (AVBP) hands-on 5h ( Computing room N17 )

          The aim will be to test some of the requirements presented in the course (such as mesh-partitioning and load balancing) to achieve high-scalability on massively parallel computers (maybe also on GPUs).

        Two examples are used to illustrate these concepts: a multi-block structured code (elsA) and an unstructured code (AVBP). Parallel computing strategies used with both flow solvers are detailed and compared. This comparison indicates that mesh-partitioning and load balancing are more straightforward with unstructured grids than with multi-block structured meshes. However, the mesh-partitioning stage can be challenging for unstructured grids, mainly due to memory limitations of the newly developed massively parallel architectures. Finally, detailed investigations show that the impact of mesh-partitioning on the numerical CFD solutions, due to rounding errors and block splitting, may be of importance and should be accurately addressed before qualifying massively parallel CFD tools for a routine industrial use.

        Speakers: Dr. Nicolas Gourdain (CERFACS), Dr. Michel Gazaix (ONERA)

 

 

Practical info

We will start with a pre-school training course at 9h in classroom II/5. You need to register before to obtain your account details for logging into workstation and supercomputer. Registration will be in front of lecture room IV/2.

We don't have enough parking places in front of the faculty. We suggest that you park at TobačnaMesto[1] that is cheap 0,5€/h and nearby with a car entrance from "Oranžova ulica". Other options are Parkirišče Ilirija[2] or Park&Ride Dolgi Most[3].

Catering during the breaks will be in front of II/5 each day. After pre-school training we will have a lunch and poster session on top of the faculty in front of the classrooms V/2 and V/5. Last minutes before 13h all participants are required to shou up there for a group photo. Then we will all go to IV/2 for school opening and introductory lectures. Hands-on training will continue at 3pm in computing room II/5. You may notice that computing rooms are slighgly overbooked. We will solve that by additional seats and ask people to work together.

You must be aware that II/5 is a large computing room with 44 workstations and this poseses a challenge for lecturers too. So, please follow instructions carefully as trainers will be unable to solve all your problems. Nevertheless, this is unique oportunity to ask and get answers from top experts in the field. So be prepared to ask questions of general interest. All lectures will be recorded for web portals[4,5]. You will not appear on the camera unless accidentaly. As there will be no amplifier and considering computers noise we ask participants to keep silence.

There is no need to bring your laptops. As nowadays everybody requires WiFi connectivity we are providing FS-GUEST SSID with the following pasword valid for the next week kMWeT24tYE
