================================================================================ HPLinpack 2.2 -- High-Performance Linpack benchmark -- February 24, 2016 Written by A. Petitet and R. 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 : 8192 NB : 512 PMAP : Column-major process mapping P : 4 Q : 1 PFACT : Right NBMIN : 32 NDIV : 2 RFACT : Right BCAST : 1ringM DEPTH : 1 SWAP : Spread-roll (long) L1 : transposed form U : 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 1.110223e-16 - Computational tests pass if scaled residuals are less than 16.0 ================================================================================ T/V N NB P Q Time Gflops -------------------------------------------------------------------------------- WC11R2R32 8192 512 4 1 0.71 5.167e+02 HPL_pdgesv() start time Web Apr 22 00:00:00 2026 HPL_pdgesv() end time Web Apr 22 00:00:00 2026 --VVV--VVV--VVV--VVV--VVV--VVV--VVV--VVV--VVV--VVV--VVV--VVV--VVV--VVV--VVV- + Max aggregated wall time rfact . . : 0.32 + + Max aggregated wall time pfact . : 0.30 + + Max aggregated wall time mxswp . : 0.19 Max aggregated wall time laswp . . . : 0.37 Max aggregated wall time update . . : 0.00 Max aggregated wall time up tr sv . : 0.00 -------------------------------------------------------------------------------- ||Ax-b||_oo/(eps*(||A||_oo*||x||_oo+||b||_oo)*N)= 0.0002689 ......
