######################################################################## This is the DARPA/DOE HPC Challenge Benchmark version 1.2.0 October 2003 Produced by Jack Dongarra and Piotr Luszczek Innovative Computing Laboratory University of Tennessee Knoxville and Oak Ridge National Laboratory See the source files for authors of specific codes. Compiled on Tue May 20 at 19:12:12 Current time (1216990442) is Tue May 20 14:54:02 2008 Hostname: 'cresco2x091.vlancresco' ######################################################################## ============================================================================ HPLinpack 1.0a -- High-Performance Linpack benchmark -- January 20, 2004 Written by A. Petitet and R. Clint Whaley, Innovative Computing Labs., UTK ============================================================================ 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 : 471680 NB : 312 PMAP : Row-major process mapping P : 4 Q : 256 PFACT : Right NBMIN : 4 NDIV : 2 RFACT : Crout BCAST : 1ringM DEPTH : 1 SWAP : Mix (threshold = 64) L1 : 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 checks will be computed: 1) ||Ax-b||_oo / ( eps * ||A||_1 * N ) 2) ||Ax-b||_oo / ( eps * ||A||_1 * ||x||_1 ) 3) ||Ax-b||_oo / ( eps * ||A||_oo * ||x||_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 Begin of PTRANS section.
