Data Type

Integer

Default Value

2

Description

This parameter controls the amount of printed output produced by calls to the matrix initialization routines RSDI, RNDI, CHDI, CSDI, CNDI and RSDANN, RNDANN, CHDANN, CSDANN, CNDANN. The print code summary table lists the values of IPRI and the output produced.

The following is a detailed description of each option. The value of IPRI 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 IPRI. The following options are available:

  • 0, No output from matrix initialization is printed.
  • +1, Start and stop timing is printed.
    The following is an example: 
     START OF FMS MATRIX INITIALIZATION
 END   OF FMS MATRIX INITIALIZATION.
 TIME(SEC): CPU   =       0.055,        WALL=       0.330
  • +2, Information about the matrix blocking is printed.
    The following is an example: 
         M A T R I X     I N I T I A L I Z A T I O N

  • +16, The matrix profile renumbering is printed from subroutine FMSPF.
  • +64, The profile you specified will be printed.
    CAUTION: For large problems this could be a lot of output.
  • +128, The profile is printed after it has been expanded for outside blocking.
    This option is only useful for profile matrices ( MFMAT=1) with outside blocking ( INSIDE=-1).
  • +256, The criteria for selecting block dimensions is printed.
    This criteria depends on the optimized kernel size NEQBLK, the matrix format MFMAT, the amount of memory MAXMD, the number of processors MAXCPU and the file striping configuration.
  • +1024, A report is printed that evaluates your profile for various compute block sizes NEQBLK and blocking patterns INSIDE. This applies to profile format matrices MFMAT=1 only. It may be useful for fine tuning a specific problem to a specific platform.
  • +2048, The matrix profile is written to file FMSLEQ and the program halts.
    This profile may later be read into program DEMO with the SPARSITY=PROFILE option. Program DEMO is useful for interactively changing FMS parameters for fine tuning.
