[OMPI users] segfault issue - possible bug in openmpi

2008-10-03 Thread Daniel Hansen
I have been testing some code against openmpi lately that always causes it to crash during certain mpi function calls. The code does not seem to be the problem, as it runs just fine against mpich. I have tested it against openmpi 1.2.5, 1.2.6, and 1.2.7 and they all exhibit the same problem. Also

Interesting. I ran a loop calling comm_spawn 1000 times without a problem. I suspect it is the threading that is causing the trouble here. You are welcome to send me the code. You can find my loop code in your code distribution under orte/test/mpi - look for loop_spawn and loop_child. Ral

Eric, In the 1.3 and some of the latest 1.2.X versions tuned is the default component for collectives. However, the tuned currently in the trunk are optimized for high performance networks (such as IB or MX), and they do not deliver the best performance on slower devices such as Ethernet.
