Thanks to those who answered my post in the past. I have to admit that you lost me about half way through the thread. I was able to get 2 of my systems cranked up and was about to put a third system online when I remembered it was running x64 version of OS. Can I just recompile the code on the

Thanks Rueti. It works now. I just disabled firewall on all machines since Open-MPI uses random port each time. Thanks again! Danesh Reuti skrev: Hi, Am 09.04.2008 um 22:17 schrieb Danesh Daroui: Mark Kosmowski skrev: Danesh: Have you tried "mpirun -np 4 --hostfile hosts

But if openmpi is installed, I can automatically instrument my application with Vampir (ie I don't have to install vtf separately - right?) And I can view with Vampir Trace the results of my app's parallel run? -Original Message- From: George Bosilca [mailto:bosi...@eecs.utk.edu]

Well, as a quick hack, you can try adding --disable-dlopen to the configure line. It will disable the building of individual components (instead linking them into the main shared libraries). It means that you have to be slightly more careful about which components you build, but in practice

I think you're expect something that the MPI profiling interface is not supposed to provide you. There is no tool to dump or print any profile information by default (and it is not mandated by the standard). What this option does, is compile the profiling interface (as defined by the MPI

thanks for reporting the bug, it is fixed on the trunk. The problem was this time not in the algorithm, but in the checking of the preconditions. If recvcount was zero and the rank not equal to the rank of the root, than we did not even start the scatter, assuming that there was nothing to do.

Hi, If I configure openmpi with "-enable-mpi-profile" option: 1) Once build is complete, how do I specify profile name and location in the "mpirun" command? Do I have to set any flags with the "mpirun" command to view profile? 2) If vampire trace by default is built with

This worked for me although I am not sure how extensive our 32/64 interoperability support is. I tested on Solaris using the TCP interconnect and a 1.2.5 version of Open MPI. Also, we configure with the --enable-heterogeneous flag which may make a difference here. Also this did not work
