?trrv2d
Receives a message from the process into the trapezoidal matrix.
Syntax
call itrrv2d( icontxt, uplo, diag, m, n, a, lda, rsrc, csrc )
call strrv2d( icontxt, uplo, diag, m, n, a, lda, rsrc, csrc )
call dtrrv2d( icontxt, uplo, diag, m, n, a, lda, rsrc, csrc )
call ctrrv2d( icontxt, uplo, diag, m, n, a, lda, rsrc, csrc )
call ztrrv2d( icontxt, uplo, diag, m, n, a, lda, rsrc, csrc )
Input Parameters
icontxt |
INTEGER. Integer handle that indicates the context. |
uplo, diag, m, n, lda |
Describe the matrix to be sent. See Matrix Shapes for details. |
rsrc |
INTEGER. The process row coordinate of the source of the message. |
csrc |
INTEGER. The process column coordinate of the source of the message. |
Output Parameters
a |
An array of dimension (lda,n) to receive the incoming message into. |
Description
This routine receives a message from process {RSRC, CSRC} into the trapezoidal matrix A. This routine is globally-blocking, that is, return from the routine indicates that the message has been received into A.
