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 : 2363136 NB : 192 PMAP : Column-major process mapping P : 41 Q : 80 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 ================================================================================ T/V N NB P Q Time Gflops -------------------------------------------------------------------------------- WC00L2L4 2363136 192 41 80 9058.40 9.71234E+05 HPL_pdgesv() start time Sun Sep 19 09:11:09 2021 HPL_pdgesv() end time Sun Sep 19 11:42:07 2021 -------------------------------------------------------------------------------- ||Ax-b||_oo/(eps*(||A||_oo*||x||_oo+||b||_oo)*N)= 0.0018537 ......
