Hi all,<br><br>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:<br><br>Fatal error in MPI_Init: Other MPI error, error stack:<br>
MPIR_Init_thread(392).................:<br>MPID_Init(139)........................: channel initialization failed<br>MPIDI_CH3_Init(38)....................:<br>MPID_nem_init(196)....................:<br>MPIDI_CH3I_Seg_commit(366)............:<br>
MPIU_SHMW_Hnd_deserialize(324)........:<br>MPIU_SHMW_Seg_open(863)...............:<br>MPIU_SHMW_Seg_create_attach_templ(763): unable to allocate shared memory - OpenFileMapping The system cannot find the file specified.<br>
<br>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. <br><br>I am attaching logs from smpd from both machines from the runs with nemesis and shm.<br>
<br>I don&#39;t have any experience with mpich, so I have no idea what the problem is. Any guidance would be appreciated.<br><br>Thanks<br><br>
