E4 Computer Engineering and Applied Micro Unveil CFD Testing Results

SANTA CLARA, CA: Enterprise Hardware solutions provider, AppliedMicro jointly with Italian High performance computing solutions provider releases test results from GPU cluster provided to EnginSoft subjected to Simulation Based Engineering Sciences. The tests were primarily conducted to evaluate the compliancy of X-Gene-based ARM processor for Computational Fluid Dynamics (CFD) applications. Here every GPU cluster was provided with E4 incorporated nodes hosting one GPU, an 8-core, 2.4 GHz 64-bit X-Gene server SoC and a low latency network to enable comparative tests with standard x86-based clusters.

With the executed set of tests, EnginSoft had the convenience to tweak the experiences in CFD and HPC in order to evaluate the first production ARM64 processor architecture alongside a GPU in a real cluster, connected by a FDR infiband and enabled E4 Computer Engineering and Applied Micro to conduct independent tests on the new E4 system. The real test for capabilities of the cluster in actual engineering environment was made when EnginSoft was made to perform a complete porting of CFD code with a computational engine based on GPU for verifying the scalability on low power, cost effective CPUs. The CFD code testing was done on Lattice Boltzmann method based, Sailfish solver.

Post pre requisite software recompilation task, supported by E4’s R&D team, Enginsoft could successfully work the complete 3D CFD software solution pulling out the same degree of performance when compared with competing high end x86-based platforms and also scoring a little higher on the power efficiency factor.

Piero Altoè, Vice President of Research & Innovation, E4 Computer Engineering speaks about the testing and EnginSoft as he quotes, “E4's mission is to deliver leading-edge high performing solutions to our wide range of customers. Our ARM-based X-Gene clusters coupled with GPUs are already implemented in universities and research centers, but it was a fantastic opportunity for us to have tests carried out by Enginsoft as this firm operates very closely within manufacturing and automotive environments. The results show that we can really make an impact in terms of performance and TCO if we implement accelerated ARMv8 cluster with high speed networks."
