Altair AcuSolve Performance
14 Dell EMC Ready Solution for HPC Digital Manufacturing— Altair Performance
4 Altair AcuSolve Performance
Altair AcuSolve is a Computational Fluid Dynamics (CFD) tool commonly used across a very wide range of
CFD and multi-physics applications. AcuSolve is a robust solver with proprietary numerical methods that yield
stable simulations and accurate results regardless of the quality and topology of mesh elements. It uses a
single solver for all flow regimes, with very few parameters to adjust, and it produces rapid results by solving
the fully-coupled pressure/velocity equation system using scientifically proven numerical techniques. CFD
applications typically scale well across multiple processor cores and servers, have modest memory capacity
requirements, and typically perform minimal disk I/O while in the solver section. However, some simulations,
such as large transient analysis, may have greater I/O demands.
Figure 4 shows the relative single server performance of the CBB server types for three AcuSolve
benchmarks.
For comparison, the figure also includes performance data for prior generations of the Ready Solution for
HPC Digital Manufacturing the 13
th
generation system using 16-core Intel E5-2697Av4 processors, and the
14
th
generation system using Intel Xeon Gold 16-core 6142 processors. Overall, the Intel 61xx (Skylake) and
62xx (Cascade Lake) 14G based servers demonstrate significantly better performance than the E5-2697Av4
based 13G system. For all benchmarks, the 16-core 6242 displayed noticeably better performance than its
6142 counterpart and the 20-core 6248 and 24-core 6252 demonstrated even better performance.
Figure 5 shows the parallel performance improvement for AcuSolve when running in parallel across multiple
servers.
