This is fixed as of r21208. Thanks for reporting it! Ralph On May 11, 2009, at 12:51 PM, Anton Starikov wrote: Although removing this check solves problem of having more slots in rankfile than necessary, there is another problem. If I set rmaps_base_no_oversubscribe=1 then if, for example:

Re: [OMPI users] *** An error occurred in MPI_Init

What versions of BLCR and Open MPI are you using? Have you tried to checkpoint/restart a single (non-MPI) application with BLCR? BLCR ships with some examples, and I would suggest trying to make sure those work before moving onto Open MPI. Typically this type of failure is the result of BLC

Re: [OMPI users] Please help me with this simple setup. i am stuck

It looks like you have a heterogeneous setup -- the error is complaining that the executable you compiled on one machine will not run on the other because the executable format is different. You'll probably need to have different executables compiled for each node (there's probably other wa

That configure option does work, but you appear to be on a system that has SLURM installed - yes? Are you planning on running with SLURM? Building --without-rte-support will remove a lot more than just the allocator and mapper. You have to be on a system like a Cray that has its own launch,
