| | 8 | An explanation of the input/output parameters follows: |
| | 9 | T/V : Wall time / encoded variant. |
| | 10 | N : The order of the coefficient matrix A. |
| | 11 | NB : The partitioning blocking factor. |
| | 12 | P : The number of process rows. |
| | 13 | Q : The number of process columns. |
| | 14 | Time : Time in seconds to solve the linear system. |
| | 15 | Gflops : Rate of execution for solving the linear system. |
| | 16 | |
| | 17 | The following parameter values will be used: |
| | 18 | |
| | 19 | N : 19360 |
| | 20 | NB : 220 |
| | 21 | PMAP : Row-major process mapping |
| | 22 | P : 2 |
| | 23 | Q : 2 |
| | 24 | PFACT : Left |
| | 25 | NBMIN : 4 |
| | 26 | NDIV : 2 |
| | 27 | RFACT : Right |
| | 28 | BCAST : 1ringM |
| | 29 | DEPTH : 0 |
| | 30 | SWAP : Mix (threshold = 64) |
| | 31 | L1 : transposed form |
| | 32 | U : transposed form |
| | 33 | EQUIL : yes |
| | 34 | ALIGN : 8 double precision words |
| | 35 | |

| | 38 | - The matrix A is randomly generated for each test. |
| | 39 | - The following scaled residual checks will be computed: |
| | 40 | 1) ||Ax-b||_oo / ( eps * ||A||_1 * N ) |
| | 41 | 2) ||Ax-b||_oo / ( eps * ||A||_1 * ||x||_1 ) |
| | 42 | 3) ||Ax-b||_oo / ( eps * ||A||_oo * ||x||_oo ) |
| | 43 | - The relative machine precision (eps) is taken to be 1.110223e-16 |
| | 44 | - Computational tests pass if scaled residuals are less than 16.0 |
