Hi,

I'm new to MPI and parallel processing in general. I have to
pack slices of 
several arrays. One natural approach seems to be to define
user 
types with MPI_TYPE_VECTOR and pack them defining a new type
with 
MPI_TYPE_STRUCT. I am able to use both of them separately,
but when 
trying to create new type consisting of vector-type
structures I get:

1 - MPI_RECV : Message truncated
p1_30689:  p4_error: : 14
rm_l_1_30690:  p4_error: interrupt SIGINT: 2

Are there some limitations of the supported types or I am
missing 
something else. How can I interpret the above message.

I will appreciate any help. Thanks in advance.

P.S. I am using MPI1.1 on a Linux cluster.
