Using ITT Event and/or Task API in Fortran

Towie__Ewan — Tue, 08 Aug 2017 11:03:12 GMT

Hi,

I wanted to use the ITT Event API (and maybe the Task API) to help mark sections of my Fortran code for profiling but there doesn't appear to any event functions in the Fortran ittnotify module?

Is there a different way to access the Event (or Task) API in Fortran? I can't seem to find anything in the manual relating to Fortran, it only refers to C/C++. Looking in ittnotify.h the correct API methods are available.

Hello Ewan,

Hello Ewan,

Please look at https://software.intel.com/en-us/node/544197 .

In sum:

1) Add the ITTNOTIFY module to your source files with the following source line:

USE ITTNOTIFY

2) Insert ITT Notifications in Your Application e.g.:

CALL ITT_PAUSE()

3) Link the libittnotify.a Static Library to Your Application.

Thanks & Regards, Dmitry

Hi Dmitry,

I already make use of the ITT pause and resume functions, they are extremely helpful.

I am trying to use the Event API of ITT which doesn't seem to be accessible through the Fortran interface. The Event API I am referring to is discussed at https://software.intel.com/en-us/node/544209

Thanks,

Ewan

Can anyone offer any help

Can anyone offer any help here?

I am looking at the C header file and the Fortran module, and I am wondering if it is just a case of defining an appropriate interface between the Fortran and C subroutines. Unfortunately, I don't think I can easily do this?

Hello Ewan,

Acknowledging that at some point we enabled only a subset of ITT API Fortran bindings.

I included the full ITT API set support to VTune plans. Stay tuned.

Thanks & Regards, Dmitry

Hi Dmitry,

Thank you! It would be good to have more access to the ITT API in Fortran and allow us to make better use of the Intel tools.

I will stay posted :)

Thanks, Ewan

Dmitry,

Just wanted to second Ewan's request for Fortran access to Events. Would be extremely helpful to my group.
