Vtune pause/resume API supported on Phi?

John_Michalakes — Tue, 29 Oct 2013 09:52:27 GMT

I’m following these instructions for calling the Vtune pause/resume API from Fortran:

http://software.intel.com/en-us/articles/how-to-call-resume-and-pause-api-from-fortran-code

but when I link I get:

api_fortran_itt.o: In function `fortran_itt_resume_':
api_fortran_itt.c:(.text+0x4): undefined reference to `__itt_resume_ptr__3_0'
api_fortran_itt.o: In function `fortran_itt_pause_':
api_fortran_itt.c:(.text+0x24): undefined reference to `__itt_pause_ptr__3_0'

I’m trying to link to the library here:

-L/opt/intel/vtune_amplifier_xe/bin64/k1om -littnotify

Is the Vtune pause/resume API supported on KNC? If so, what is the correct library and link option, please?

Support for this was first

Support for this was first announced in VTune update 13 (current). Another update may be needed.

I upgraded to the 21 Oct. 2013 (Update 14) of Vtune and same problem as before. But then discovered that it will link properly if

-L/opt/intel/vtune_amplifier_xe_2013/bin64/k1om -littnotify

comes at the end of the link-line, after the api_fortran.o file. Probably would have worked with the Update13 version. Just following up here in case anyone else gets tripped up by this. Thanks for the reply, -John
