Тема: Re: [starpu-devel] Customization/Optimization for Scheduling Methods
Hello,
Sorry for the delay, I was on summer vacation.

Well, as usual papers don't provide enough room to describe the details
:/
The comments in the mps and lp files are what will be the most
details. Which questions are you still wondering?
> 2. Are the functions in src/profiling/bound.c ready for use?
They are supposed to be, yes.

Which problem are you experiencing? I tried to run it quickly on my
machine and got the expected outputs.

Ah, that's something that could be added indeed.

It is mostly a proof of concept for now, thus not exposing it cast in
stone for now. But it should be usable, up for people to try and fix.
