要旨

In this thesis we look at a performance bottleneck of running molecular dynamics code on GPGPU devices (specifically the CUDA platform), namely random memory access into global graphics card memory. We offer a solution that involves reordering memory blocks in order to enable more memory reads from the local cache (shared memory) instead of the global memory. For determining a memory block order that sufficiently increases performance a space-filling curve was used. Significant performance increases for higher filling fractions were observed with a molecular dynamics simulation that was written from scratch.
