     tors

INPUT PARAMETERS
     A	    - The sparse matrix
     x	    - The contiguous block of input vectors
     comm   - The communication structure for A

	    - the number of input vectors
     procinfo
	    - the usual processor information

OUTPUT PARAMETERS
     b	    - on exit these vectors contain A*x

RETURNS
