- 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 : 28800
- NB : 192
- PMAP : Row-major process mapping
- P : 2
- Q : 2
- PFACT : Right
- NBMIN : 4
- NDIV : 2
- RFACT : Crout
- BCAST : 1ringM
- DEPTH : 1
- SWAP : Mix (threshold = 64)
- 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 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
