[OMPI users] mpi_init waits 64 seconds if vpn is connected

I am having a problem on my linux desktop where mpi_init hangs for approximately 64 seconds if I have my vpn client connected but runs immediately if I disconnect the vpn. I've picked through the FAQ and Google but have failed to come up with a solution. Some potentially relevant information: I a

Re: [OMPI users] Problem with mpiexec --cpus-per-proc in multiple nodes in OMPI 1.6.4

Thank you, Ralph. I will try to use a rankfile. In any case, the --cpus-per-proc option is a very useful feature: for hybrid MPI+OpenMP programs, for these processors with one FPU shared by two cores, etc. If it gets fixed in a later release of OMPI that would be great. Thank you, Gus Correa

Re: [OMPI users] Problem with mpiexec --cpus-per-proc in multiple nodes in OMPI 1.6.4

I've heard this from a couple of other sources - it looks like there is a problem on the daemons when they compute the location for -cpus-per-proc. I'm not entirely sure why that would be as the code is supposed to be common with mpirun, but there are a few differences. I will take a look at it

Dear Open MPI Pros I am having trouble using mpiexec with --cpus-per-proc on multiple nodes in OMPI 1.6.4. I know there is an ongoing thread on similar runtime issues of OMPI 1.7. By no means I am trying to hijack T. Mishima's questions. My question is genuine, though, and perhaps related to his

Hmmm...okay, let's try one more thing. Can you please add the following to your command line: -mca ras_base_verbose 5 -mca rmaps_base_verbose 5 Appreciate your patience. For some reason, we are losing your head node from the allocation when we start trying to map processes. I'm trying to track

[OMPI users] 32-/64-bit library problem in openmpi-1.7rc8r28176 and openmpi-1.9r28175

Hi today I tried to build openmpi-1.7rc8r28176 and openmpi-1.9r28175 on "Solaris 10, x86_64" and "Solaris 10, sparc" with "Sun C 5.12". I used the following commands for openmpi-1.7.x and similar commands for the other package: ../openmpi-1.7rc8r28176/configure --prefix=/usr/local/openmpi-1.7_64_

Re: [OMPI users] Possible bug in OpenMPI 1.6.3 in selecting v4 or v6 network addresses on the same adaptor

Hi, You can use the btl_tcp_disable_family and oob_tcp_disable_family MCA parameters to disable the use of a specific IP family addresses. Set both parameters to 6 to disable IPv6 or set them both to 4 in order to disable IPv4. Kind regards, Hristo > -Original Message- > From: users-bou

[OMPI users] Possible bug in OpenMPI 1.6.3 in selecting v4 or v6 network addresses on the same adaptor

Hi I've been fighting trying to run comparitive test of IMB using OpenMPI 1.6.3 on the same node using an Intel Truescale card and the onboard Ethernet. Turns out that all of the problems were due to the IP v6 addresses being firewalled on the nodes but OpenMPI was trying to use the IPv6 add
