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 accelerated the most computational intensive parts (80\%--95\%) of BLAST on NVIDIA GPUs with the CUDA programming model. Several 2D and 3D problems were tested and achieved an overall speedup of 4.3 on 1 M2050.
