Re: [Starpu-devel] StarPU 1.2.0 not working with CUDA 8 and Ubuntu

[Gabriel Gazolla <gabrielgazolla@gmail.com>]

Hello Samuel,

I formated the computer, reinstaled ubuntu 14.04 and CUDA 8...
the CUDA software you sent me to compile and test (test.c) is running fine as I sent you the last output. But I receive nvcc warnings that you already know about the architecture, they are very annoying...

I made the starpu folder writable and build folder also.

I ran the configure with verbose enabled the output is attached.

I also ran the make check with option you recommend me, make check -k.
the execution log is attached.
i am also sending u sudo make install log

Also is attached execution of starpu_machine_display it looks like it worked fine.

What i think I made different is using the -k option on the make check - k part , I think thats why its working now...

the starpu.log file are empty, all of them in all folders: tools, test, examples and stencil.

Here are some questions:

1) Why do you think it worked now ? because of the option -k ?

2) Do you think everything is working fine? or maybe because i turned off the errors, maybe theres still errors there?

3) when are you going to release a new starpu version ?

4) am I receiving a lot of messages during starPU execution because of the configure with verbose mode ?

"[starpu][_starpu_terminate_workers] wait for worker 2
[starpu][_starpu_terminate_workers] wait for worker 3
[starpu][_starpu_barrier_destroy] reached_exit 0"

I would really appreciate to receive your feedback, I will try to install now on ubuntu 16 with CUDA 8 and see if it works,

Thanks,

Joao

Ah, that's unfortunately due to this:

In verbose mode, starpu writes some logs to the starpu.log file, so the
current directory needs to be writable.  You can specify another file
destination thanks to the STARPU_LOGFILENAME environment variable.

Also, I probably forgot: please run

make check -k

-k meant to make it continue even on some errors, so as to get most
available information.
