Dear list,
I have raised the following question during yesterday's workshop at ISC:
We do operate a facility-wide centralized storage infrastructure to
which a number of different client systems (clusters) are connected.
None of the client system alone is capable of saturating the bandwidth
of the system and hence any IO500 submission using a single system will
not be representative for the performance/capabilities of the overall
I/O subsystem.
We are interested in a benchmark execution mode that would allow to
assess the center-wide performance level. One possible option would be
to allow summing up concurrently executed IOR runs that have a
sufficiently large overlap. At least for the IOR easy/hard cases that
would be a sensible number.
Thank you for your consideration.
Best regards,
Dorian Krause
