Figure 1: Performance comparison with and without Singularity
Singularity at Scale
We ran HPL across multiple nodes and compared the performance with and without container. All nodes are Dell PowerEdge C4130
configuration G with four P100-PCIe GPUs, and they are connected via Mellanox EDR InfiniBand. The result comparison is shown in
Figure 2. As we can see, the percent performance difference is within ± 0.5%. This is within normal variation range since the HPL
performance is slightly different in each run. This indicates that MPI applications such as HPL can be run at scale without performance
loss with Singularity.
