Hi JG,

Thanks a lot for sharing your finding and solution with the list!  Sorry only today I was able to forward it to the list: I was on vacation until July 14, then the sourceforge list server was down for a few days, then I mistakenly handled the moderation of this mail.

Thanks,
Rui

Hi,

I am testing perfsuite/1.1.4 on Cray/XC (PizDaint) and i noticed an issue with
papi. It looks like that if i configure perfsuite with
         --with-papi=/opt/cray/papi/5.4.0.1, psrun

psrun will fail with:
         Error 101 for CUDA Driver API function 'cuCtxCreate'. cuptiQuery failed
even if i do not use cuda at all in my code.

Solution is to use a papi compiled without cudatoolkit then psrun will
run fine, as you can see here:
         https://bitbucket.org/jgphpc/pug/issue/29/perfsuite-bluewaters
         (look for Cupti issue).

I am wondering if you experience the same issue on your XK ?

Regards, jg.
