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
