Define Documentation

#define SKYLARK_SKETCH_HPP   1

This test ensures that the sketch application (for CombBLAS matrices) is done correctly (on-the-fly matrix multiplication in the code is compared to true matrix multiplication). This test builds on the following assumptions:

• CombBLAS PSpGEMM returns the correct result, and
• the random numbers in row_idx and row_value (see hash_transform_data_t) are drawn from the promised distributions.
