Hi, All, 

I met with an issue that when run mpich-3.2.1 with SGE grid. After reading the wikipage https://wiki.mpich.org/mpich/index.php/Using_the_Hydra_Process_Manager, I tried to run a 4 process application on SGE but still get the following error:
    "error: executing task of job 151347 failed: execution daemon on host "host1" didn't accept task"
"error: executing task of job 151347 failed: execution daemon on host "host1" didn't accept task"
"error: executing task of job 151347 failed: execution daemon on host "host1" didn't accept task"

Here is the list of commands I tried to run:
mpiexec -n 4 - f  machine_file ./my_executable
mpiexec -rmk sge -n 4 -f machine_file ./my_executable
mpiexec -launcher sge -n 4 -f machine_file ./my_executable
mpiexec -rmk sge -launcher sge -n 4 -f machine_file ./my_executable

Has anyone can share with me successful experience on running mpich in sge? Or can anyone point me how to fix this error? 

Appreciate your help ahead!

Thanks,
Shuwei
