 .SH USE OF IN-PLACE OPTION
-When the communicator is an intracommunicator, you can perform an all-gather operation in-place (the output buffer is used as the input buffer). Use the variable MPI_IN_PLACE as the value of both \fIsendbuf\fR and \fIrecvbuf\fR. In this case, \fIsendcount\fR and \fIsendtype\fR are ignored. The input data of each process is assumed to be in the area where that process would receive its own contribution to the receive buffer. Specifically, the outcome of a call to MPI_Allgather that used the in-place option is identical to the case in which all processes executed \fIn\fR calls to
