Possibilities of ExaGeoStat

Operations:

1. Generate synthetic spatial datasets (i.e., locations & environmental measurements).
2. Maximum likelihood estimation using dense, Diagonal Super Tile (DST), and Tile Low-Rank (TLR) covariance matrices.
3. Task-based programmin model and dynamic runtime system using HiCMA, CHAMELEON, and StarPU.
