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(,) ‘GetDevice k…
CUDA Toolkit 12.4 introduced a new nvFatbin library for creating fatbins at runtime. Fatbins, otherwise known as NVIDIA device code fat binaries, are containers that store multiple versions of code to store different architectures. In particular, NVIDIA uses them to bundle code for different GPU...
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 ...

This section describes how to use the GPU virtualization capability to isolate the computing power from the GPU memory and efficiently use GPU device resources.You have p
The CUDA device function in this file operates as follows: All threads copy the relevant part of the input grid into shared memory, including the halo. The threads synchronize with one another to ensure shared memory is ready. Threads that fit in the output grid perform the Game of Life ...
