HPLinpack 2.2  --  High-Performance Linpack benchmark  --   February 24, 2016
Written by A. Petitet and R. Clint Whaley,  Innovative Computing Laboratory, UTK

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

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      :    8192 
NB     :    4096 
PMAP   : Column-major process mapping
P      :       4 
Q      :       1 
BCAST  :  1ringM 

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

- 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
