The p?copy routines perform a copy operation with distributed vectors defined as
sub(y) = sub(x),
where sub(x) and sub(y) are n-element distributed vectors.
sub(x) denotes X(ix, jx:jx+n-1) if incx=m_x, and X(ix: ix+n-1, jx) if incx= 1;
sub(y) denotes Y(iy, jy:jy+n-1) if incy=m_y, and Y(iy: iy+n-1, jy) if incy= 1.
(global) The length of distributed vectors, n≥0.
(local)
Array, size (jx-1)*m_x + ix+(n-1)*abs(incx)).
This array contains the entries of the distributed vector sub(x).
(global) The row and column indices in the distributed matrix X indicating the first row and the first column of the submatrix sub(X), respectively.
(global and local) array of dimension 9. The array descriptor of the distributed matrix X.
(global) Specifies the increment for the elements of sub(x). Only two values are supported, namely 1 and m_x. incx must not be zero.
(local)
Array, size (jy-1)*m_y + iy+(n-1)*abs(incy)).
This array contains the entries of the distributed vector sub(y).
(global) The row and column indices in the distributed matrix Y indicating the first row and the first column of the submatrix sub(Y), respectively.
(global and local) array of dimension 9. The array descriptor of the distributed matrix Y.
(global) Specifies the increment for the elements of sub(y). Only two values are supported, namely 1 and m_y. incy must not be zero.
Overwritten with the distributed vector sub(x).
