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

HPLinpack 1.0a -- High-Performance Linpack benchmark

-- January 20,

2004

Written by A. Petitet and R. Clint Whaley, Innovative

Computing Labs.,

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: 12000

NB : 200

PMAP

: Row-major process mapping

P

:
