can anyone provide a simple example of launching mpich distribution application with SGE? and explain the integration of MPICH3 with lsf, sge....? Thanks, Shuwei On Mon, Jun 25, 2018 at 3:15 PM, Shuwei Zhao <[email protected]> wrote:

Hi,

I'm a bit confused by the correct way for interacting mpiexec with sge. here is my original way of interacting mpich2 with sge successfully but failed with mpich3.

1. using qsub submit 2 subjobs at the same time: qsub -P bhosts - pe mt 1 ./myscript qsub -P bhosts - pe mt 1 ./myscript 2. Using lock file handle to a temporary file to decide master and slave. 3. Both master and slave echo host name to a hosts file. 4. run mpiexec -n 2 -f hosts ./mybinary(this one always fail) 5. I tried to change command in 4th to mpiexec -launcher sge -n 2 -f hosts ./mybinary but also fails.

as mpiexec -help says, mpiexec will automatically interact with resource manager like sge, lsf, I'm a bit confused about the right way to interact with sge. do you know what's wrong with my application?

Thanks, Shuwei
