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 : 926208
NB : 384
PMAP : Column-major process mapping
P : 8
Q : 10
PFACT : Left
NBMIN : 4
NDIV : 2
RFACT : Left
BCAST : 1ring
DEPTH : 0
SWAP : Binary-exchange
L1 : no-transposed form
U : no-transposed form
EQUIL : no
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 2.220446e-16
- Computational tests pass if scaled residuals are less than 16.0
