Hi all, I am OK if we cancel too, but at the next meeting we hold, I wanted to do an update about FA-MPI work and answer questions people have about our approach to it.
Since this came up a couple calls ago.  It would be fine to wait for next call slot to do this... We are actively extending FA-MPI at this time.

I'm okay if we cancel.

On a different note, I wanted to ask the group about the error handler
for MPI_Init. As I look into the problem of MPI re-initialization, I
came across some questions, which I'm not been able to answer myself by
reading the standard:

- Since one cannot set an error handler before MPI_Init, is is expected
that MPI_ERRORS_ARE_FATAL is enabled when MPI_Init is called? If that is
the case, one can assume that if an error occurs the first time MPI_Init
is called (let's assume in the future we can call MPI_Init several
times), MPI will abort?

- Is there any situation, in which MPI_Init could return an error code
if a failure occurs?

- Is there a way to set MPI_ERROR_RETURN in COMM_WORLD before calling

I realize this was discussed in 2010, but I'm not sure if the forum
found a solution:
