One of many very important aspects in global ocean and atmosphere modeling is the type of grid used, as well as the accuracy of the grid. In the new MPAS model, we are using Spherical Centrodial Voronoi Tessellations (SCVTs) as the grids we do our computations on. These grids must be generated by some type of software, and can get quite large when we are thinking of realistic model runs. Sometimes these grids can take days to generate due to the accuracy we want for the grid. To help speed up this process, I have implemented an SCVT generator that works on a graphics processing unit, using OpenCL. This talk will explain the basics of SCVT generation, as well as the numerical methods used in this code,and will give a brief explanation OpenCL code used, as well as the potential benefits.
