Abstract :
The BLAST code implements a high-order numerical algorithm that solves the equations of compressible hydrodynamics using the Finite Element Method in a moving Lagrangian frame. BLAST is coded in C++ and parallelized by MPI. We accelerate the most computationally intensive parts (80%-95%) of BLAST on an NVIDIA GPU with the CUDA programming model. Several 2D and 3D problems were tested and a maximum speedup of 4.3x was delivered. Our results demonstrate the validity and capability of GPU computing.
