Abstract. We present FATSEA, a functional and performance evalua-
tion simulator written in C++ to handle kernels written in the CUDA
programming language aimed for GPGPU computing. FATSEA takes
a Parallel Thread eXecution (PTX ) code as input, which is a device
independent code format generated by the Nvidia CUDA compiler, to
validate results and estimate performance on Nvidia platforms. This pa-
per shows results on a G80-based architecture for a set of well-known
kernels to illustrate the usefulness of our framework while performing a
preliminary validation for the tool.
