description         High Performance Computing Linpack Benchmark
long_description    See how your machine compares to the TOP500! \
                    HPL is a software package that solves a (random) dense linear \
                    system  in double  precision (64 bits) arithmetic on \
                    distributed-memory computers. It can thus be regarded as a \
                    portable as well as freely available implementation of the \
                    High Performance Computing Linpack Benchmark.
