HPLinpack
1.0 --
High-Performance Linpack benchmark
-- September 27, 2000
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 :
2400 2600 2800
3000 3200
NB :
60 60
P :
1
Q :
5
PFACT :
Crout
NBMIN :
4
NDIV :
2
RFACT :
Right
BCAST :
1ringM
DEPTH :
1
SWAP : Mix (threshold = 60)
L1 : transposed form
U : transposed form
EQUIL : yes
ALIGN : 8 double precision words
----------------------------------------------------------------------------
-
The matrix A is randomly generated for each test.
-
The following scaled residual checks will be computed:
1) ||Ax-b||_oo / ( eps * ||A||_1 * N
)
2) ||Ax-b||_oo / ( eps * ||A||_1 * ||x||_1
)
3) ||Ax-b||_oo / ( eps * ||A||_oo *
||x||_oo )
-
The relative machine precision (eps) is taken to be 1.110223e-16
-
Computational tests pass if scaled residuals are less than 16.0

Finished 10 tests with the following results:
10 tests completed and passed
residual checks,
0 tests completed and failed
residual checks,
0 tests skipped because of
illegal input values.
