LINPACK and MP LINPACK Benchmarks 10Note that the non-hybrid version may be used in a hybrid mode, but it would be missingsome of the optimizations added to the hybrid version. Non-hybrid builds are the default.In many cases, the use of the hybrid mode is required for system reasons, but if there is achoice, the non-hybrid code may be faster, although that may change in future releases. Touse the non-hybrid code in a hybrid mode, use the threaded MPI and Intel MKL, link with athread-safe MPI, and call function MPI_init_thread() so as to indicate a need for MPI tobe thread-safe.ContentsThe Intel Optimized MP LINPACK Benchmark for Clusters includes the HPL 1.0a distributionin its entirety as well as the modifications, delivered in the files listed in Table 10-2 andlocated in the ./benchmarks/mp_linpack/ subdirectory in the Intel MKL directory (seeTable 3-1):Table 10-2Contents of the MP LINPACK Benchmark./benchmarks/mp_linpack/testing/ptest/HPL_pdtest.csrc/blas/HPL_dgemm.csrc/grid/HPL_grid_init.csrc/pgesv/HPL_pdgesvK2.cinclude/hpl_misc.h andhpl_pgesv.hsrc/pgesv/HPL_pdgesv0.ctesting/ptest/HPL.datMake.ia32Make.em64tMake.ipfHPL.datHPL 1.0a code modified to display captured DGEMMinformation in ASYOUGO2_DISPLAY (see details inthe New Features section) if it was captured.HPL 1.0a code modified to capture DGEMM informationif desired from ASYOUGO2_DISPLAYHPL 1.0a code modified to do additional gridexperiments originally not in HPL 1.0.HPL 1.0a code modified to do ASYOUGO andENDEARLY modificationsBugfix added to allow for 64-bit address computation.HPL 1.0a code modified to do ASYOUGO, ASYOUGO2,and ENDEARLY modificationsHPL 1.0a sample HPL.dat modified.(New) Sample architecture make for processors usingIA-32 architecture and Linux.(New) Sample architecture make for processors usingIntel® 64 architecture and Linux.(New) Sample architecture make for IA-64architecture and Linux.A repeat of testing/ptest/HPL.dat in the top-leveldirectory10-5

It is recommended that you edit themto fit your specific configuration. In particular:• Set TOPdir to the directory MP LINPACK is being built in.• You may set MPI variables, that is, MPdir, MPinc, and MPlib.• Specify the location of Intel MKL and of files to be used (LAdir, LAinc, LAlib).• Adjust compiler and compiler/linker options.• Specify the version of MP LINPACK you are going to build (hybrid or non-hybrid) bysetting the version parameter for the make, for example,make arch=em64t version=hybrid install10-6
