Lattice QCD GPU Inverters on ROCm Platform
Yujiang Bi, Yi Xiao, WeiYi Guo, Ming Gong, Peng Sun, Shun Xu, Yi-Bo Yang · EPJ Web of Conferences · 2020
The open source ROCm/HIP platform for GPU computing provides a uniform framework to support both the NVIDIA and AMD GPUs, and also the possibility to porting the CUDA code to the HIP-compatible one. We present the porting progress on the Overlap fermion inverter (GWU-code) and also the general Lattice QCD inverter package - QUDA. The manual of using QUDA on HIP and also the tips of porting general CUDA code into the HIP framework are also provided.
