I am using nvfortran 23.11 and Cuda 12.3 - just updated both. Previously, I was able to use cudaGetDeviceProperties as in: istat = cudaGetDeviceProperties(prop, 0) if(istat /= cudaSuccess) then write(,) ‘GetDe
In this chapter, we examine the opportunities presented by the new CUDA programming environment for advanced solver techniques in the context of physics simulation. The involved numerics have not been a major problem on the previous GPU generation, but the missing flexibility with...

Our experience implementing kernels in CUDA is that the most efficient thread configuration partitions threads differently for the load phase and the processing phase. The load phase is usually constrained by the need to access the device memory in a coalesced way, which requires a specifi...
1. Using Inline PTX Assembly in CUDA The NVIDIA® CUDA® programming environment provides a parallel thread execution (PTX) instruction set architecture (ISA) for using the GPU as a data-parallel computing device. For more information on the PTX ISA, refer to the latest version of ...
