It is possible when converting to formats like DIA that the conversion will be unsuccessful. At that point the tuner in TuneMultiply should be assigned with timings in a way that they will be discarded later on (std::numeric_limits<double>::max()??).

In addition, the RunFirstTuner should be able to discard formats like that from the best format selection process.

• Update README.md with the project description and purpose.
• Add BUILD.md and provide build instructions and flags.

The high level interface at:

does not include the vectors used in the multiply operation and we are allocating those under the hood as dense vectors. Need to change the interface to something like:

template <typename ExecSpace, typename DynamicMatrix, typename Vector, typename Tuner>
void tune_multiply(DynamicMatrix& mat, const Vector& x, const Vector& y, Tuner& tuner)

The benefits from doing so are two-fold:

1. Avoid possible interface duplications in the case the multiply is either between matrices or other sparse vectors
2. Avoid the allocation of memory under-the-hood

• Change IO routines such that the trees loaded in DecisionTreeTuner and RandomForestTuner are binary files
• Random forest configuration is loaded from a single file instead from a directory
