| 50 | An explanation of the input/output parameters follows: |
| 51 | T/V : Wall time / encoded variant. |
| 52 | N : The order of the coefficient matrix A. |
| 53 | NB : The partitioning blocking factor. |
| 54 | P : The number of process rows. |
| 55 | Q : The number of process columns. |
| 56 | Time : Time in seconds to solve the linear system. |
| 57 | Gflops : Rate of execution for solving the linear system. |
| 58 | |
| 59 | The following parameter values will be used: |
| 60 | |
| 61 | N : 40220 |
| 62 | NB : 200 |
| 63 | PMAP : Row-major process mapping |
| 64 | P : 2 |
| 65 | Q : 2 |
| 66 | PFACT : Right |
| 67 | NBMIN : 4 |
| 68 | NDIV : 2 |
| 69 | RFACT : Crout |
| 70 | BCAST : 1ringM |
| 71 | DEPTH : 0 |
| 72 | SWAP : Binary-exchange |
| 73 | L1 : transposed form |
| 74 | U : transposed form |
| 75 | EQUIL : yes |
| 76 | ALIGN : 8 double precision words |
| 77 | |

| 80 | - The matrix A is randomly generated for each test. |
| 81 | - The following scaled residual check will be computed: |
| 82 | ||Ax-b||_oo / ( eps * ( || x ||_oo * || A ||_oo + || b ||_oo ) * N ) |
| 83 | - The relative machine precision (eps) is taken to be 2.220446e-16 |
| 84 | - Computational tests pass if scaled residuals are less than 16.0 |
