Std TCP/IP stack
it hung with an unknown but large(ish) quantity of data. when I ran just one
Bcast it was fine but Bcasts in lots in separate MPI_WORLD's hung. - All the
details are in some recent posts.
I could not figure it out and moved back to my PVM solution.

Thanks Jeff! Different subnets. All 10GigE's are on 192.168.x.x and
all 1GigE's are on 10.0.x.x

Hi,
I used a 'tee' command to capture the output but I forgot to also redirect

This is what a fresh make gave (gcc 4.1.2 again) :

ompi_debuggers.c:81: error:
Ummmthe configure log terminates normally, indicating it configured fine.
The make log ends, but with no error shown - everything was building just fine.
Did you maybe stop it before it was complete? Run out of disk quota? Or...?

My MPI version is 1.4.1. This isn't the latest but still fairly
recent. So I assume th

Thanks Randolph! That's interesting to know! What was the hardware you
were using? Does your bcast fail at the exact same point too?

Dear OMPI users,
I configured and installed OpenMPI-1.4.2 and BLCR-0.8.2. (blade01 �C

After the installation, I can see the ‘blcr’ module loaded correctly
(lsmod | grep blcr). And I can also run ‘cr_run’, ‘cr_

Hello OpenMPI developers,
I am searching for a way to discover _all_ configure options of an
OpenMPI installation.
Background: in a existing installation, the ompi_info program helps to
find out a lot of informations about the installation. So, "ompi_info
-c" shows *some* configuration optio
