Hi all,
I have a program that executes a communication loop similar to this one:
1:for(int p1=0; p1
Hello,
I think that my problem:
http://www.open-mpi.org/community/lists/users/2012/05/19182.php
is similar to yours. Following the advice in the thread that you posted:
http://www.open-mpi.org/community/lists/users/2011/07/16996.php
I have tried to run my program adding:
-mca btl_openib_flags 305
I have tried to add "-mca btl_openib_flags 305" and it worked ^^. Now I
am trying to understand why and which is the impact in performance.
Thank you anyway for your suggestion,
Jorge

I hope this one is completely right:
1: for(int p1=0; p125) cout<<"p1("<25) cout<<"p1("<25) cout<<"p2("<25) cout<<"p2("< At 11:52 04/05/2012, you wrote:

Don't worry ;).
I simplified the core of the problem just to make it easier to

Yes, with 1.4.4 was worse (it hanged in a previous part of the real code
with communications also involved) but with 1.4.5 it still hangs :( .
Now I see that in the first post there is another mistake :S , the
