I am trying to run VTune on KNL but am running into the following error:
$ amplxe-cl -collect hpc-performance openmc
amplxe: Error: both cgroup and no-aggregation modes only available in
system-wide mode
usage: perf stat [<options>] [<command>]
-G, --cgroup <name> monitor event in cgroup name only
-A, --no-aggr disable CPU count aggregation
-a, --all-cpus system-wide collection from all CPUs
This command works fine on a Haswell node, but breaks when I run it on KNL.
I am able to run VTune with the "hotspots" collection argument without on
KNL. Does anyone know how to resolve this issue?
Thanks,
Will

FWIW based upon my experience trying unsuccessfully to debug why NWChem
won’t run in the Vtune GUI, I recommend always using Vtune CLI. It’s a bad
habit to get used to fancy features like GUIs and dynamic memory allocation
if you want to be a serious HPC person ;-)

Thank you Michael and Jeff. Downloading the results from the VTune CLI and
importing them into the VTune GUI locally works great.

Hi Will,
You can use the command line interface to collect the profiling
information. For example:
Ø amplxe_cl –collect hotspots ./a.out
You can then move the results (entire directory) over to the environment
(Windows or Linux) in which you would like to view the results.

I am interested in profiling an application on the Phi using Intel VTune. I
would like to use the graphical interface for VTune, but have been unable
to launch VTune remotely using my local instance of VTune. Does anyone have
any recommendations for how to remotely profile my application on the Phi
but view the results locally with the VTune GUI on my workstation?
Thanks,
Will
