[OMPI users] Unable to find the following executable

Hi there, I am new to using mpi commands and was stuck in problem with running a code. When I submit my job through a batch file, the job exits with the message that the executable could not be found on the machines. I have tried a lot of options such as PBS -V and so on on but the problem

Re: [OMPI users] Error when using OpenMPI with SGE multiple hosts

More than OGE uses external bindings. We have tested it using some tricks, and in environments where binding is available from the RM (e.g., slurm). So we know the basic code works. Whether or not it works with OGE is another matter. On Wed, Nov 17, 2010 at 9:09 AM, Terry Dontje

This is due to the interface defined for MPI_File_write that specifies an integer for the length. The positive value of an integer are coded in hexadecimal from to 7FFF FFF and negative values are coded from 8000 to . (7FFF is exactly 2^31-1). Pascal Ricardo Reis

Hi, I'm interested in what is expected from OGE/SGE in order to support most of your scenarios. First of all the "-binding pe" request is not flexible and makes only sense in scenarios when having the same architecture on each host, each involved host is used exclusively for the job (SGE
