SET_GRID_SIZE

This procedure sets the process grid size for the parallel matrix engine.

Usage

The SET_GRID_SIZE stored procedure has the following syntax:

SET_GRID_SIZE(gridSizeRow,gridSizeCol)

Parameters

gridSizeRow: The number of rows in the process grid.; Type: INT4
gridSizeCol: The number of columns in the process grid.; Type: INT4

Returns

BOOLEAN TRUE always.

Details

This procedure is rarely needed, since nzm..initialize() typically sets the process grid size to a reasonable default value. To resize the process grid with a redistribution of currently-existing matrices use the nzm..SET_GRID_SIZE_WITH_REDISTRIBUTE procedure.

Examples

call nzm..set_grid_size(2,2);
