	)

Only left sketch is supported for now

Only randomization is supported for now

TODO: Read the entries!

Run the test for elemental matrices

Depending on which sketch is requested, do the sketching

Set up the iterative solver parameters

Solve the exact problem

Solve the sketched problem---change to using the sketched regressor

Check the quality of the solution

Finalize Elemental

Run the test for CombBLAS matrices

Depending on which sketch is requested, do the sketching

int int_params[NUM_INT_PARAMETERS]

This file cannot be built without CombBLAS and Elemental both being present. The accompanying CMakeLists.txt checks for both libraries to be available.
