?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.
