Altair Radioss Performance

5 Altair Radioss Performance
Altair Radioss is a leading structural analysis solver for highly non-linear problems under dynamic loadings. It
is used across all industries worldwide to improve the crashworthiness, safety, and manufacturability of
structural designs. Radioss is similar to AcuSolve in that it typically scales well across multiple processor
cores and servers, has modest memory capacity requirements, and performs minimal disk I/O while in the
solver section. It is tightly integrated with Altair OptiStruct™ and it comes with a comprehensive material and
rupture library.
Figure 7 shows the relative performance for two Radioss benchmarks on single servers. For this comparison,
all processor cores were utilized while running Radioss.
Like Figure 4, performance data for PowerEdge R7425 systems using AMD EPYC 7451(24-core) and
7601(32-core) processors was included for a comparison, with the performance from the PowerEdge R7425
equipped with dual 24-core 7451 processors used as the basis of 1.0. Here, a higher value is better. The
results are similar to the AcuSolve results, where the increase in performance from the 1
st
generation EPYC
to the 2
nd
generation EPYC based systems is noticeable both in terms of core performance and overall
system performance. Again the 64-core EPYC 7702 system delivered noticeably better overall performance
than the other systems.
Figure 8 presents the Radioss parallel performance with parallel benchmarks run across multiple servers.
