[mvapich-discuss] messege truncated

[Justin]

The message means mpi received a message larger than the buffer size you 
specified.  Namely in this case the buffer length is '-514665432'  thus 
any length of message would be bigger than it.  What I find odd is the 
parameters you are sending MPI_Recv.  You are sending a count of 
'945075466'  are you really sending a message that is a gigabyte in 
size?  It might be possible that the count is being converted to a 
signed int causing it to wrap to a negative number.  Check the size that 
you are specifying for the buffer.  It is odd that you have it specified 
to be a GB in size when you are only receiving 2 bytes.
