QDP-JIT: A QDP++ Implementation for CUDA-Enabled GPUs
Frank Winter · Proceedings of 31st International Symposium on Lattice Field Theory LATTICE 2013 — PoS(LATTICE 2013) · 2014
These proceedings describe briefly the QDP-JIT/PTX framework for lattice field theory calcula- tions on the CUDA architecture. The framework generates compute kernels in the PTX assembler language which can be compiled to efficient GPU machine code by the NVIDIA JIT compiler. A comprehensive memory management was added to the framework so that applications, e.g. Chroma, can run unaltered on GPU clusters and supercomputers.
