[MPICH] error in MPI_Waitall

[Rajeev Thakur]

Signal 11 means there was a segmentation fault; that is, the program
accessed a memory location that it was not assigned. It is most likely a bug
in your code.

Subject: [MPICH] error in MPI_Waitall



Hi,
 
I am trying to run an MPICH2 application over 2 processors on a dual
processor x64 Linux box (SuSE 10). I am getting the following error message:
 
------------------------------
Fatal error in MPI_Waitall: Other MPI error, error stack:
MPI_Waitall(242)..........................: MPI_Waitall(count=2,
req_array=0x5bbda70, status_array=0x7fff461d9ce0) failed
MPIDI_CH3_Progress_wait(212)..............: an error occurred while handling
an event returned by MPIDU_Sock_Wait()
MPIDI_CH3I_Progress_handle_sock_event(413):
MPIDU_Socki_handle_read(633)..............: connection failure
(set=0,sock=1,errno=104:Connection reset by peer)
rank 0 in job 2  Demeter_18432   caused collective abort of all ranks
  exit status of rank 0: killed by signal 11
------------------------------
 
The "cpi" example that comes with MPICH2 executes correctly. I am using
MPICH2-1.0.5p2 which I compiled from source. 
 
Does anyone know what the problem is?
 
cheers
steve
