?gesd2d
Takes a general rectangular matrix and sends it to the destination process.
Syntax
call igesd2d( icontxt, m, n, a, lda, rdest, cdest )
call sgesd2d( icontxt, m, n, a, lda, rdest, cdest )
call dgesd2d( icontxt, m, n, a, lda, rdest, cdest )
call cgesd2d( icontxt, m, n, a, lda, rdest, cdest )
call zgesd2d( icontxt, m, n, a, lda, rdest, cdest )
Input Parameters
icontxt |
INTEGER. Integer handle that indicates the context. |
m, n, a, lda |
Describe the matrix to be sent. See Matrix Shapes for details. |
rdest |
INTEGER. The process row coordinate of the process to send the message to. |
cdest |
INTEGER. The process column coordinate of the process to send the message to. |
Description
This routine takes the indicated general rectangular matrix and sends it to the destination process located at {RDEST, CDEST} in the process grid. Return from the routine indicates that the buffer (the matrix A) may be reused. The routine is locally-blocking, that is, it will return even if the corresponding receive is not posted.
