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

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.
