1 Platform Choices for LS-DYNA Manfred Willem and Lee Fisher High Performance Computing Division, HP October, 2004 Public Benchmarks for LS-DYNA administered by University of California, San Diego (Prof. David Benson) Refined Neon and 3 Vehicle Collision models for LS-DYNA 2 E - I - 1
2 CAE / IT I 3. LS-DYNA Anwenderforum, Bamberg 2004 LS-DYNA Neon from PA-RISC to IPF Faster 0:25 0:45 1:09 hh:mm Observation: 1.5GHz Itanium is 70% faster than old Itanium (fall, 2002) Reference: LS-DYNA v Refined NCA Neon model for public benchmarks, 535K elements, posted as of 1-Oct-04 at: 3 LS-DYNA Neon Power4 SP2 cluster IBM Power4 (1.7GHz) AIX SP2 (11/03) Observation: Itanium faster than Power4 at 2-8 CPUs Power4 faster above 8 due to low latency switch vs. GigE Reference: LS-DYNA v Refined NCA Neon model for public benchmarks, 535K elements. IBM data posted 13- Nov-03 at: 4 E - I - 2
3 LS-DYNA Neon Xeon GigE & Myrinet Xeon (3.06GHz) Linux GigE (3/04) Xeon (3.06GHz) Linux Myrinet (3/04) IBM Power4 (1.7GHz) AIX SP2 (11/03) Observations: Reference: LS-DYNA v Refined NCA Neon model for public benchmarks, 535K elements. at 16 CPUs, Xeon adds half again as much time as Itanium scalability of GigE Xeon & Itanium track each other; scalability of Myrinet & SP2 track each other 5 LS-DYNA Neon Itanium InfiniBand Xeon (3.06GHz) Linux GigE (3/04) Xeon (3.06GHz) Linux Myrinet (3/04) IBM Power4 (1.7GHz) AIX SP2 (11/03) HP RX2600 (1.5GHz) HP-UX InfiniBand (3/04) Observation: low latency InfiniBand switch puts Itanium/HP-UX in the lead Reference: LS-DYNA v Refined NCA Neon model for public benchmarks, 535K elements. 6 E - I - 3
4 CAE / IT I 3. LS-DYNA Anwenderforum, Bamberg 2004 What about Opteron? All preceeding data is v this version does NOT include native recompile for x86-64 (e.g. Opteron) New v was released 3-Aug-04, supporting x86-64 no vendor has posted Opteron data at TopCrunch using this official release yet LSTC has improved general Faster performance by ~30% in this new release (contact algorithm) therefore, BEWARE any 8 comparison of hardware 6 performance that mixes 4 LS-DYNA versions! 2 also, insure runs do not leave 0 HP Itanium 1.5GHz HP Itanium 1.5GHz HP Opteron idle CPUs in any nodes v v (classic benchmark trick) 1/seconds LS-DYNA 2-CPU Performance +30% gain (2.2GHz) v HP Xeon64 (3.4GHz) v Reference: HP internal data. x86-64 data will be posted upon official release of HP-MPI library by HP. 7 Itanium Optimized for Speed 8 E - I - 4
5 Lowering Itanium platform cost 9 Value of HP Itanium platform increases as problems becoming more complex Bigger models LS-DYNA 3 Vehicle Benchmark run CPUs Longer duration runs Double Precision math is more efficient on 64-bit processors LS-DYNA for Implicit FEA requires 64-bit address space and fast I/O 10 E - I - 5
6 CAE / IT I 3. LS-DYNA Anwenderforum, Bamberg 2004 Benchmark Summary HP encourages hardware vendors and customers to use TopCrunch We offer choice: all leading architectures Itanium/Xeon/Opteron clusters and SMP servers HP Itanium is the performance leader today x86 is price/performance leader today Technological changes will continue HP will consistently be a leader in performance & reliability 11 HP Platform Recommendations for LS-DYNA? - it depends! 12 E - I - 6
7 HP Servers & Clusters for CAE Scalability of CAE Applications 100 % CFD CPU Efficiency Impact Structural Analysis CPUs Used by Single Job 13 HP: Platform of Choice for LSTC c8000 rx CPUs HP-UX & Linux64 xw bit desktops for LS-DYNA (all CAD + CAE pre/solve/post) rx CPUs HP-UX rx CPUs Itanium2 HP-UX & Linux64 Superdome CPUs HP-UX SMP Itanium Servers for CAE (great throughput on all solvers; easy admin; adaptive enterprise) dl585 4 CPUs Opteron Linux64 Quad-CPU Servers for LS-DYNA (fast; all solvers; easy admin) XC Clusters HP middleware Itanium turnkey system HP-UX or Linux X86-64 Linux rx16x0 (1u 2p) dl140 or dl145 (1u 2p) GigE or InfiniBand GigE or Myri / Infini Dedicated Clusters for LS-DYNA (best price/performance) 14 E - I - 7
