Altair Radioss Performance
18 Dell EMC Ready Solution for HPC Digital Manufacturing— Altair Performance
Figure 8 presents the Radioss parallel performance with parallel benchmarks run across up to 8 servers.
The figure uses the performance reference of 1.0 for a single node equipped with the Intel 6142. The overall
parallel scalability for these models is good, behaving as expected, where the larger model shows better
overall scalability. The single node performance improvement of the servers equipped with 6252 processors
over the servers equipped with the 6142 processors is maintained for these benchmark runs up through eight
nodes.
Like AcuSolve, it is also possible to use Radioss in hybrid parallel mode. Figure 9 shows the parallel
performance for both Radioss benchmarks models using (1,2,4) shared memory threads on up to 8 compute
nodes.
