Clint Whaley, Innovative Computing Laboratory, UTK Modified by Piotr Luszczek, Innovative Computing Laboratory, UTK Modified by Julien Langou, University of Colorado Denver ================================================================================ 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 : 286848 NB : 384 PMAP : Row-major process mapping P : 4 Q : 4 PFACT : Left NBMIN : 2 NDIV : 2 RFACT : Left BCAST : 2ring DEPTH : 1 SWAP : Spread-roll (long) L1 : no-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 2021-03-05 13:43:18.665 2021-03-05 13:45:12.054 ================================================================================ T/V N NB P Q Time Gflops -------------------------------------------------------------------------------- WR02L2L2 286848 384 4 4 113.39 1.388e+05 -------------------------------------------------------------------------------- ||Ax-b||_oo/(eps*(||A||_oo*||x||_oo+||b||_oo)*N)= 0.0000080 ......
