OpenACC

And they identified that perfect hashing and the compact hashing.

So they implemented in OpenCL and we wrote this portable GPU implementation, the perfect hashing and the compact hashing implementation for the computational meshes in the different implementation including CUDA, HIP, Cocos, Raja, OpenACC, OpenMP, SQL, around eight implementations and we compare the perfect hashing with the compact hashing.

So this is the computational mesh and this is the refined mesh, adaptive mesh and this is the refined mesh and this is the sparse matrix corresponding to this fine mesh and then means this can be stored in the hash table and perfect hash table to space to save the space this can be stored into the compact hash table.

So, and this means for these computational structures, we need the, for computation, we need to look for the neighbors, top right-left neighbors.
