How do I change data size (matrix and vector simensions) for the tests?

Only HPL and PTRANS matrix sizes can be changed directly in the hpccinf.txt input file. The remaining tests use the size of the HPL matrix to adjust the size of their input data. For example if the size of the HPL matrix is 1 GiB then each of the three vectors used by STREAM will be 0.333 GiB.

Only HPL and PTRANS matrix sizes can be changed directly in the hpccinf.txt or hpccmemf.txt input files. The remaining tests use the size of the largest HPL matrix to adjust the size of their input data. For example, in a sequential run, if the size of the HPL matrix is 1 GiB then each of the three vectors used by STREAM Triad will be 0.333 GiB, PTRANS matrix will be 0.5 GiB, the FFT vector size will be 125 MiB, and each of the three matrix sizes in DGEMM will be 333 MiB.
