Hi,

I have a question:

If I have an array with negative indices, say defined as A(-5:5) in Fortran.

Can I use that for COLLECTIVE CALL, e.g MPI_Bcast, MPI_Gather without
transforming
to a new array with positive indices?

If I have my array defined as A(0:11), I find no issues.

Hope you can help me.


Thanks and best regards,

- Himadri
