Hi mpich team,
My team had a issue met in mpich-3.2.1 as Xiaopeng mentioned before. As you replied, the bug was fixed in mpich-3.3.1.
However as I installed mpich-3.3.1, finished integration and launched test.
Single machine is fine. But cross machine only doesn’t work in SGE environment while it works well in lsf.
For me it still works fine. We have no SSH in the cluster and all is started solely by `qrsh -inherit …` on the slave nodes. Master of the parallel job: 11870 ?

Processes spawned procedure
From above, we can see that process spawned like this:
Sge_execd -> sge_shepherd > mpiexec -> hydra_pmi_proxy -> my_process
From above, we can see that process spawned like this:
Sge_execd -> sge_shepherd > mpiexec -X-> hydra_pmi_proxy -> my_process
If you are able to track the pid and ppid, Looks like hydra_pmi_proxy is unable to spawn when run with mpich-3.3 on sge environment. Could you please help confirm is it a potential bug or there is something that I didn’t take care of?
Thanks,
Shuwei
