Hi,
MPI_Allreduce works for me with MPI_INTEGER8 for all OpenMPI
versions up to 1.4.3. However, with OpenMPI 1.5.1 I get a
failure at runtime:
[proton:23642] *** An error occurred in MPI_Allreduce: the reduction
operation MPI_SUM is not defined on the MPI_INTEGER8 datatype
[proton:23642] *** on
Is that what it reports on the remote node?
I am guessing you are just using ssh to launch remotely -- try this:
ssh othernode env | grep PATH
Ensure that the answer you get back is what you expect. Sometime shell startup
files do different things if they're invoked interactively vs.
The exact contents of the environment variables as reported by 'env' are:
PATH=/usr/lib/qt-3.3/bin:/usr/kerberos/sbin:/usr/kerberos/bin:/usr/lib/ccache:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin:/usr/lib/openmpi/bin:/home/mpiuser/bin
LD_LIBRARY_PATH=/usr/lib/openmpi/lib

Hello,
Please don't worry about this for now, the problem stems from
iptable rules. But, I still think putting usb0 into the reject
list should disable the ip-address associated with it.

Hello,
I am working on a distributed array data structure built on top of the one-sided

hi folks,
sorry to insist, i'll be glad if someone could point out the relevant
piece of info I missed.
these huge memory consumption cannot be explained easily on the user
side, especially since it's only seen on the master process node...
thanks,

I'm trying to setup a small cluster of 2 nodes.
Both nodes are running Fedora 11 Kernel 2.6.29.4, have the same user
mpiuser with the same password. Both of them have their env vars set
as follows in /etc/profile itself:
PATHusr/lib/openmpi/bin
LD_LIBRARY_PATH
