Performance Comparisons of Relion without the optimization
Figure 3 shows Relion performances without the code optimization. The bars labeled with ‘Intel E5-2697 v4’ are from the Intel’s
publication. In the CPU test results, Relion v2.0.3 took 47.6 hours on Intel E5-2697 v4 (Broadwell) whereas the same version of Relion
took 34.5 hours on Dell EMC PowerEdge C6420 and the latest version of Relion (Relion2-beta-v2.0) took 32.8 hours on Dell EMC
PowerEdge R740xd.
Unfortunately, a GPU currently available, NVIDIA Tesla V100, is not compatible with Relion v2.0.3. Hence, the test was performed with
Relion2-beta-v2.0. Therefore, the results for GPU tests are not fair comparisons.
NVIDIA Tesla V100 with 16GB memory performs similar to the result from 2 nodes – 8 rank test in Figure 2.
Figure 2 Optimized Relion Benchmark Comparisons with Intel®’s results and Dell EMC PowerEdge C6420. The storage used for
the tests were Dell EMC Isilon, F800 and H600. Intel’s results shown here were using Lustre as a storage system; However, we
were not able to run our tests with Dell EMC Lustre Storage due to the limited availability.
