The QUDA is a library for calculating in lattice QCD on GPUs. This includes optimized Dirac operations and many fermion solvers and CG implementations have been provided. More details can be found at QUDAs github.
QUDA_RESOURCE_PATH is where several tuning files will be generated on the first run. This can be stored anywhere with read/write permissions are available. They are used on all subsequent runs for that system.
The first run on each system/configuration can take up to 2-3x longer due to generating these tuning files. It is recommended to run the provided QUDA benchmark once, to generate these tuning files, before processing a workload.
