Parallel Computing: is there any good forum?

[hempyelmo]

Hi all,

I've got a specific problem related to parallel programming and I was looking for a comprehensive, exhaustive, friendly forum on that particular subject. After 30 minutes of intense googling I didn't find any forum that suits my needs.

So, do you know some good forums on parallel programming/processing/debugging/whatever'ing' where I can get in touch with other people directly associated with this field? In my search I found a post (http://ubuntuforums.org/showthread.php?t=869309) on this forum and I decided to take a chance here.

For those interested: I'm looking for an open source tracing visualization software (like Vampir or ITAC but... open source...) working with MPI. I thought TAU was the answer but it seems it don't come with a visualization tool. Also, there is LTT (Linux Tracing Tool) but I have to patch the kernel and it's maybe too much for what is needed.

Thanks! Sorry for the typos if any!

Maybe a bit more oriented toward hardware than what you are looking for, but still full of interesting info.

The beowulf mailing list is friendly and full of advice if you can show that you made at least a bit of research (aka googleing and list archive) first.

Hmmm, it seems a mailing list is the only way to ask questions on those specific subjects.

By the way I resolved my problem: TAU can be installed with compatibility wit slog2 format which can be then visualized with jumpshot.

Thanks anyway! ;)
