CrossprodAllocator allocates and populates the input to the
matrix cross product dense matrix kernel for the purposes of conducting a
single performance trial with the CrossprodMicrobenchmark function.
The matrices or vectors corresponding to the index parameter must be
allocated, initialized and returned in the kernelParameters list.CrossprodAllocator(benchmarkParameters, index)DenseMatrixMicrobenchmark specifying various parameters
