Brady,
Thanks. I probably will pick your brain more, if you don't mind as I
delve further into this.

Hi - Intel Cluster Checker person chiming in.
To answer your question Prentice about runtime of Cluster Checker (CLCK), this
will depend on which set of tests or framework definition (FWD) you use and the
number of servers. The default fwd, is health_base which should run in a matter
of seconds. It was designed to run quickly and be a sanity check before running
jobs. Other FWDs are designed for cluster hand-off and validation; so these
will take much longer as they run a multitude of different benchmarks on
individual nodes (stream/dgemm/sgemm/...) and across the cluster
(hpcg/hpl/pairwise imb/...) looking for outliers. Which can take 90+ minutes to
multiple hours depending on the system configuration and size. Of course there
are inbetween tests also such as health_extended_user or mpi_prereq_user.
Couple of tips - clck -X list is a great way to see what framework definitions exist.
clck -X <name_of_fwd> will give you more details on what is being checked for
the specific fwd.
Thanks for using cluster checker and providing feedback. Happy to help further.
-Brady

Subject: Re: [Beowulf] Intel Cluster Checker
i played with it about a year ago since i get it as part of the intel compiler
bundle we pay for. it was overly complicated to install and run and didn't
seem worth while. kind of like getting a piece of ikea furniture but then
trying to use a phillips screw driver to build it instead of the little wrench.
otherwise when i dug into what it was actually doing, it didn't seem to be
doing anything magical. it was just doing it 'the intel way', which in my
experience is generally very strange

Beowulfers,
Have any of you used the Intel Cluster Checker? I've been tasked with
using it, and I think I have it running, but the documentation isn't
very good. I was wondering how long a typical run on some cluster
nodes should take.
Prentice
