Benchmarking RELION2 GPU-accelerated jobs on Comet-GPU nodes

Below you will find the results of running the standard RELION2 benchmark on a number of different node configurations to optimize speed vs. ‘cost’ (in service units, SUs).

Optimal configuration for COSMIC² users: 8 x K80 GPUs (which is across 2 nodes) is worth it – nearly double the speed, but only a fraction more SUs to pay for it.

Fastest analysis: 12 x P100 GPUs (which made it also the most ‘expensive’)
