[OMPI users] MPI_Allreduce for MPI_INTEGER8 in 1.5.1?

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. non-

[OMPI users] Problem with running MPI programs on machines with multiple interfaces

Hello, I have two mahcines each having 3 live interfaces: lo, eth0 (interanet) and usb0 (internet). eth0 cannot access usb0 on the other machine (and vice-veras). Now, when I try to run the MPI program with these two hosts I cannot get any output, even --mca

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, éloi On 01/03/2011 09:57 AM, Eloi Gau
