To run a larger LINPACK benchmark that uses more nodes, CPU cores, or memory, you will need to replace the existing HPL.dat file next to the xhpl binary with a new customized file.

Should see a bunch of tests on the screen, with the following summary at the end: Finished 864 tests with the following results:Ĩ64 tests completed and passed residual checks,Ġ tests completed and failed residual checks,Ġ tests skipped because of illegal input values. Download scientific diagram LINPACK (25000 tests) benchmark across tested infrastructures. The result of a successful compile should be the creation of the executable located inside the program directory " bin/GNU_atlas/xhpl" Program Execution - Basics If you screw up and get an error when compiling, make sure to clean out old compilation garbage before trying again: make clean_arch_all arch=GNU_atlas With the announcement of the current TOP500 list on Jat the International Supercomputer Conference ISC12 in Hamburg, the IBM Sequoia rose from 17th place to first place in the LINPACK benchmark list of the most powerful computers in the world. (satlas is the single-threaded version of Atlas, while tatlas is the multi-threaded version)Ĭompile for that specific architecture. Further, libcblas.a is deprecated - use libtatlas.so instead. We'll be using the MPI compiler wrapper (mpicc) directly which provides this functionĬhange 4: The BLAS variables () need to point to the correct locations. Make the following changes to the Makefile:Ĭhange 1: ARCH needs to match the name of the Makefile:Ĭhange 2: TOPdir needs to be set to the folder containing the makefileĬhange 3: Clear out the MPI variable.
