This PR inherits commits originally introduced in PR #67. The discussion of some of the details can also be found there. The list of changes is as follows: 1. Introduces a CMake build option for GPU support (specifically, CUDA support) in RandLAPACK. This is enabled with ``-DRequireCUDA=ON``. 2. Introduces rl_cuda_kernels.cuh - file contains various utility GPU functions, including some BLAS and LAPACK-level routines. 3. Introduces rl_cqrrpt_gpu.cuh, - a GPU version of CQRRPT. Note that since many parts of CQRRPT (including sketching) do not (currently) have GPU versions, the data offload happens inside of the algorithm. The input data is expected to be located on a CPU. 4. Introduces rl_cqrrp_gpu.cuh - a GPU version of CQRRP algorithm, which accepts data allocated on a GPU. 5. Includes tests for the functions from the above files and benchmarks (living in test space) for CQRRP algorithm. In the future, these should be moved into benchmarking space (built separately). For now, we can avoid running these with the rest of the tests by using `ctest --gtest_filter=-*bench*`. Issues #77 - #80 are related to this PR. --------- Co-authored-by: Riley John Murray <[email protected]> Co-authored-by: Riley John Murray <[email protected]> Co-authored-by: Max Melnichenko <[email protected]> Co-authored-by: rileyjmurray <[email protected]>

Better yet, we remove benchmarks from the test infrastructure.
