HP recommends Windows 7.IntroductionThe purpose of this document is to provide information that will aid in selection of HP Workstations for running ANSYSMechanical, Fluent and CFX. A performance study was completed on the ANSYS 14.0 benchmarks. Detailed results areprovided for the HP Z820 and HP Z800 Workstations running Windows 7 Professional 64-bit1. Results are also providedwith use of the NVIDIA Tesla C2075 on ANSYS Mechanical benchmarks. Recommended configurations are provided forthe new HP Workstations HP Z420, HP Z620 and HP Z820. Tips are also provided for running the solutions at ultimateperformance.The HP Z820 speedup compared to the HP Z800 is significant.All the HP Z820 ANSYS 14.0 Mechanical, Fluent and CFX results were better than HP Z800.The NVIDIA Tesla C2075 can help with ANSYS 14.0 Mechanical DMP analysis.The HP Z420, HP Z620 and HP Z820 can be configured with sufficient memory and NVIDIA Tesla C20752 to improveANSYS 14.0 Mechanical.What type of application is ANSYS Mechanical?ANSYS Mechanical is used for mechanical and structural engineering analysis/simulation. The solution is used tocompute the response of a structural system. The equation solvers that are used to drive the simulation arecomputational intensive. The solvers can run in central processing units (CPU) or graphics processing unit (GPU). Thelarge arrays of equation solvers and datasets used in the simulation require a large, fast memory system. The datastorage files accessed during simulation benefit from dedicated, fast storage I/O systems. The application has the abilityto use parallel computing (both shared memory and distributed memory). The distributed memory model can run localon host machine or across machines/nodes connected via high speed interconnect.What type of application is ANSYS Fluent?ANSYS Fluent is used for fluid flow design engineering analysis. The solvers are computational intensive and requiremoderate size, fast memory system. The application has the ability to use parallel computing and can run local on hostmachine or across machines/nodes connected via high speed interconnect.What type of application is ANSYS CFX?ANSYS CFX is used for general purpose computational fluid dynamics (CFD). The solvers are computational intensiverequire moderate size, fast memory system. The application has the ability to use local parallel computing or distributeparallel computing across multiple machines/nodes connected via high speed interconnect.How does the new HP Workstation family (HP Z420, HP Z620 and HP Z820) provide ultimate ANSYS performance?Compute performance is improved over previous-generation Intel Xeon processor-based workstations. The new HPWorkstations utilize the Intel Xeon processor E5 family and the Intel C602 chipset3. Intel AVX is a new 256 bitinstruction set extension to SSE and is designed for applications that are Floating Point (FP) intensive. It was releasedearly 2011 as part of the Intel Xeon E5-XXXX processor family3. ANSYS 14.0 was compiled to utilize Intel AVX. The HPZ420, HP Z620 and HP Z820 Workstations provide significant performance gains and utilize the Intel Xeon E5-XXXXprocessors3.Memory bandwidth and latency is improved. Dual QPI links in parallel with up to 8 GT/s.Memory speed (1600 MHz) is improved.Memory design is improved with 4 channels per processorHP Z420 supports un-buffered DIMMs (UDIMM) 8 DIMM sockets, 4 channels, 2 DIMMs per channelHP Z620 supports un-buffered DIMMS (UDIMM) and registered DIMMS (RDIMM) 12 DIMM sockets, 4 channels 2 DIMMs per channel – CPU0 – 8 sockets 1 DIMM per channel – CPU1 – 4 sockets2
HP recommends Windows 7.HP Z820 supports un-buffered DIMMs (UDIMM), registered DIMMS (RDIMM) and load-reduced DIMMS 1333 MHz (LRDIMM) Mixing UDIMM / RDIMM / LRDIMM is not permitted 16 DIMM sockets, 4 channels 2 DIMMS per channel – CPU0 – 8 sockets 2 DIMMS per channel – CPU1 – 8 socketsStorage I/O4,5 performance is improved. PCI-Express 3.0, 6 Gb/s SATA and SAS ports, DMA bandwidth, 6 Gb/s hard drives(HDD) and 6 Gb/s solid state drives (SSD) can be configured with RAID 0 striped volumes for speed, USB 3.0GPU compute acceleration (NVIDIA Tesla C2075) is a supported option in the HP Z420, HP Z620 and HP Z8202Workstations.HP Workstations and ANSYS Performance BenchmarksHP Z820 vs. HP Z800—DMPWhat ANSYS Mechanical 14.0 distributed memory parallel processing (DMP) improvement did HP measure on HP Z820?

Ideal to keep all ANSYS process memory used in physical memory. See the v14sp-6benchmark results on HP Z800 when analysis is starved of physical memory.For best performance, use same total memory size on each channel. Use same total size on each CPU.Models are growing. ANSYS 14.0 benchmarks are real examples.

The buffer cacheprevents slower Disk I/O transactions. Memory is much faster than disk I/O. Additional memory for the OS is necessary.HP Z420, HP Z620 and HP Z820 chipset design has 6 Gb/s and 3 Gb/s disk I/O ports. The 6 Gb/s I/O ports arerecommended for 6 Gb/s devices.3 Gb/s devices will negotiate 3 Gb/s protocol when plugged into 6 Gb/s ports.A dedicated RAID0 disk configuration should be used for ANSYS I/O demands. This is particularly important when ANSYSI/O files grow beyond available physical memory. 2-3x 6 Gb/s SSD RAID0 disk configurations are recommended.4 3-4x 6 Gb/s HDD RAID0 disk configurations are recommended. 47

HP recommends Windows 7.Notes1 64-bit computing on Intel architecture requires a computer system with a processor, chipset, BIOS, operating system,device drivers and applications enabled for Intel 64 architecture. Processors will not operate (including 32-bitoperation) without an Intel 64 architecture-enabled BIOS. Performance will vary depending on your hardware andsoftware configurations. See intel.com/info/em64t for more information.2 NVIDIA Tesla C2075 on the HP Z820 requires the 1125W power supply.3 Intel’s numbering is not a measurement of higher performance.4 SATA hardware RAID is not supported on Linux systems. The Linux kernel, with built-in software RAID, providesexcellent functionality and performance. It is a good alternative to hardware-based RAID. Please ual/c00060684/c00060684.pdf for RAID capabilities with Linux.HP Z200 does not support RAID 10 Because of drive bay limitation.5 For hard drives, 1 GB 1 billion bytes. TB 1 trillion bytes. Actual formatted capacity is less. Up to 20 GB of hard drive(or system disk) is reserved for system recovery software for Windows 7.6 Multi-Core technologies are designed to improve performance of multithreaded software products and hardwareaware multitasking operating systems and may require appropriate operating system software for full benefits. Notall customers or software applications will necessarily benefit from use of these technologies.7 Each processor supports up to 2 channels (HP Z220 CMT/HP Z220 SFF) or 4 channels (HP Z420/HP Z620/HP Z820) ofDDR3 memory. To realize full performance at least 1 DIMM must be inserted into each channel. To get full 8 channelsupport, 2 processors MUST be installed.8 AMD Graphics are not supported when there are greater than 32 GB of system memory present.9 Intel Turbo Boost technology requires a PC with a processor with Intel Turbo Boost capability. Intel Turbo Boostperformance varies depending on hardware, software and overall system configuration. Seeintel.com/technology/turboboost for more information.10 Intel HT Technology (HT) is designed to improve performance of multi-threaded software products and requires acomputer system with a processor supporting HT and an HT-enabled chipset, BIOS and operating system. Pleasecontact your software provider to determine compatibility. Not all customers or software applications will benefitfrom the use of HT. See intel.com/info/hyperthreading for more information.
