  HPLinpack 2.0  --  High-Performance Linpack benchmark  --   September 10, 2008

  ================================================================================

  An explanation of the input/output parameters follows:
  T/V    : Wall time / encoded variant.
  N      : The order of the coefficient matrix A.
  NB     : The partitioning blocking factor.
  P      : The number of process rows.
  Q      : The number of process columns.
  Time   : Time in seconds to solve the linear system.
  Gflops : Rate of execution for solving the linear system.

  The following parameter values will be used:

  N      :   25000
  NB     :     768
  PMAP   : Row-major process mapping
  P      :       2
  Q      :       2
  PFACT  :    Left
  NBMIN  :       2
  NDIV   :       2
  RFACT  :    Left
  BCAST  :   1ring
  DEPTH  :       1
  SWAP   : Spread-roll (long)
  L1     : no-transposed form
  U      : no-transposed form
  EQUIL  : yes
  ALIGN  : 8 double precision words

  --------------------------------------------------------------------------------

  - The matrix A is randomly generated for each test.
  - The following scaled residual check will be computed:
        ||Ax-b||_oo / ( eps * ( || x ||_oo * || A ||_oo + || b ||_oo ) * N )
  - The relative machine precision (eps) is taken to be               1.110223e-16
  - Computational tests pass if scaled residuals are less than                16.0

                1 tests completed and passed residual checks,
                0 tests completed and failed residual checks,
                0 tests skipped because of illegal input values.
