The importance of developing standards for computational and message passing interfaces is discussed. 0. You will need to add this subdirectory to the library search path of your compiler (typically via the LD_LIBRARY_PATH environment variable or the -L option to your compiler) and link to the library itself with -lcp2k. The benchmark results reported herein may need to be revised as additional testing is. To allow a comparison to other libraries, parameters for the benchmark of the pgemm_ssb function are selected, such that the same operation can be expressed in a p?gemm call through a ScaLAPACK interface. I am confused that a call to the ScaLAPACK TOOLS routine SL_INIT initializes the process grid and routine Cblacs_gridinit( &ictxt, "Row", nprow, npcol ) is also for initializing a grid (I saw that in fortran sample code). This is done by BLACS and grid setup. Packaging Guide.
