[mpich-discuss] Amazon ec2 Windows machine

[Nicholas Sgro]

Hi all,

I am trying to run the example cpi.exe across 2 amazon ec2 instances
running windows. I have different problems depending on the channel I
choose. If I try nemesis, I get the following error:

Fatal error in MPI_Init: Other MPI error, error stack:
MPIR_Init_thread(392).................:
MPID_Init(139)........................: channel initialization failed
MPIDI_CH3_Init(38)....................:
MPID_nem_init(196)....................:
MPIDI_CH3I_Seg_commit(366)............:
MPIU_SHMW_Hnd_deserialize(324)........:
MPIU_SHMW_Seg_open(863)...............:
MPIU_SHMW_Seg_create_attach_templ(763): unable to allocate shared memory -
OpenFileMapping The system cannot find the file specified.

If I try to use shm, cpi.exe uses 100% of the processors on both machines,
but makes no progress and I have to cancel the job.

I am attaching logs from smpd from both machines from the runs with nemesis
and shm.

I don't have any experience with mpich, so I have no idea what the problem
is. Any guidance would be appreciated.

Thanks
