Re: [Starpu-devel] StarPU : impossible de compiler avec SimGrid, MPI et Fxt sur PlaFRIM

Hello,

Thanks Florent for the suggestion.

Good idea, Ludo. Indeed, in the starpu-simgrid case, the fxt overhead is much 
less critical than in the actual starpu case, and it might not be worth
maintaining two separate guix packages.

Maybe the only point is to make sure the user is aware that fxt is around so 
that he / she thinks to play with the STARPU_FXT_TRACE environment variable
( https://files.inria.fr/starpu/doc/html/OfflinePerformanceTools.html )
in order to disable them at runtime. One way to make sure the user is aware
of that is to name the (guix) package accordingly, for instance 
starpu-simgrid-fxt . This would be consistent with the starpu-fxt package
naming. (And there would not be a starpu-simgrid (guix) package anymore.)

Best regards,

Manu
