[mvapich-discuss] MPIDI_CH3U_Buffer_copy(64): Message truncated; 16 bytes received but buffer size is 16

[Hari Subramoni]

Hello Jefff,

This is a little weird. This error typically occurs when the library is
expecting X bytes of data and it got more than the expected amount.
However, from the error message it seems like the expected and actual
amount of data is the same (16 bytes).

Can you give a little more information as to the kind of application you
are running here? Could you please let us know how you built MVAPICH2? If
you can give us the output of <install-dir>/bin/mpiname -a, it will help.

MVAPICH2-1.9 is a little old. Since then, we have fixed several errors and
made several performance improvements. In this context, I would like to
check if you tried your application with the latest version of MVAPICH2
(MVAPICH2-2.0b) available from the following link?

Regards,
Hari.
