Hello, Would any of you be aware of a benchmark out there which performs both strong scaling and weak scaling for non-contiguous/sequential accesses parallel I/O?
For eg, in IOR , the work per process/processor/node is constant. Hence an increase in processes/processors/nodes will increase the total amount of data written to the remote disk. This is how I have used IOR. And this would classify as weak scaling. However I am looking for a benchmark which performs strong scaling wherein the overall work is constant and irrespective of varying the processes/processors/nodes. AFAIK IOR does not perform strong scaling. I have heard that the NAS benchmarks perform strong scaling, but do they also perform weak scaling? Moreover are the accesses non-contiguous?
