.SH NOTES
|
|
Packit Service |
c5cf8c |
MPI_Aint_diff produces a new MPI_Aint value that is equivalent to the difference
|
|
Packit Service |
c5cf8c |
between addr1 and addr2 arguments, where addr1 and addr2 represent addresses
|
|
Packit Service |
c5cf8c |
returned by calls to MPI_GET_ADDRESS. The resulting address is valid only at the
|
|
Packit Service |
c5cf8c |
process that generated addr1 and addr2, and addr1 and addr2 must correspond to
|
|
Packit Service |
c5cf8c |
locations in the same object in the same process. The difference is calculated
|
|
Packit Service |
c5cf8c |
in a manner that results the signed difference from addr1 to addr2, as if the
|
|
Packit Service |
c5cf8c |
process that originally produced the addresses had called
