KNL coprocessor, MPSS, hStreams

Mukundhan_S_ — Fri, 10 Feb 2017 22:24:13 GMT

We received couple of KNL co-processor's along with a xeon processor from Intel. I have installed RHEL 7.3 and MPSS 4.3.2

Example commands works well - micinfo, miccheck, micctrl -s (Pass)
[root@em64tn ~]# micctrl mic0 -sv
mic0:
state: online
post code: 0xff
micprun
- -bash-4.2$ micprun
  ERROR: No mic cores found
  Make sure that the MPSS service has been started.
[root@em64tn ~]# service mpss status
Redirecting to /bin/systemctl status mpss.service

Hint: Some lines were ellipsized, use -l to show in full.
I try to run some examples which offload's through pragma directives to the target mic, but i get
- ./_results/intel_ilp64_parallel_sointel64/pardiso_sym.out >./_results/intel_ilp64_parallel_sointel64/pardiso_sym.res
  offload error: cannot start process on the device 0 (error code 22)
I want to make sure my MPSS is properly installed before going to hStreams which is completely another mystery. Any Intel folks with an experience on KNL coprocessors, please throw in your tips.

Hi Mukundhan,

Hi Mukundhan,

You need to set SSH password-less to connect to mic0, and source the composer's compilervars.sh before running that tool.

Thanks,

Out of curiosity, I searched for product announcements on KNL coprocessor and didn't find anything.

Yes i have it set it up for passwordless, but i am unable to source it as the composer is in /opt/intel directory which the mic currently does not see it. I have sourced that in the host prior to the program execution.

Thanks the search, i know and that's why i posted here.

Software support for newly

TimP — Sun, 12 Feb 2017 13:48:29 GMT

Software support for newly announced products tends to remain under NDA for months after hardware release. You should have a hardware support account where you could file a request, but they tend not to like to discuss NDA software on these forum pages.

Thanks Tim, yes i am in discussion with my Intel representative as well. Just thought the community might be able to input some feedbacks as KNL MPSS and KNC MPSS are similar.

Thread can be closed, as it is Intel confidential and this might not be the right place i can find a solution.

Thank you all for your inputs.
