FMS Printing Parameter IPRDV

Data Type

Default Value

DESCRIPTION:

The following is a detail description of each option. The value of IPRDV you specify is obtained by adding together the numeric value of each option you select. Because these numeric values are a power of 2, they have the effect of setting bits in IPRDV.

• 0
  No output from vector-diagonal-vector multiply is printed.

• +1
  Start and stop timing is printed. The following is an example:

   START OF VECTORS-DIAGONAL-VECTORS MULTIPLY
   END   OF VECTORS-DIAGONAL-VECTORS MULTIPLY.
   TIME(SEC): CPU   =       2.484,        WALL=       2.516
  

• +2
  Timing information for each vector group is printed. The following is an example:

   F M S     V E C T O R S   -   D I A G.   -   V E C T O R S     M U L T I P L Y
   <----FUNCTION--->   <--VECTORS-->     <-CPU  TIME(SEC)->     <-WALL TIME(SEC)->
                       FIRST    LAST     DELTA        TOTAL     DELTA        TOTAL
   V*D*V MULTIPLY          1      54     1.668        1.668     1.749        1.749
   V*D*V MULTIPLY         55     100     0.795        2.463     0.849        2.598
  

• +4
  The {X} and {Y} vectors are printed before multiplication.

• +8
  The output matrix [F] = {X}T[D]{Y} is printed.

• +16
  The {X} vectors are printed after diagonal multiplication, {X}T[D].

• +64
  The diagonal matrix [D] is printed.

• +1024
  The actual performance achieved in Megaflops is printed. This computation is based on an actual count of the number of floating point operations (adds and multiplies) required and the actual time spent.

CAUTION: For large problems this parameter can produce a lot of output. You can use the FMS Parameters NEQPR1 and NEQPR2 to create a window on the matrix and vector terms printed.
