Some PTX instructions are only supported on devices of higher compute capabilities. For example,Warp Shuffle Functionsare only supported on devices of compute capability 3.0 and above. The -arch compiler option specifies the compute capability that is assumed when compiling C to PTX code. So, code...

NVVM IR is a compiler IR (intermediate representation) based on the LLVM IR. The NVVM IR is designed to represent GPU compute kernels (for example, CUDA kernels). High-level language front-ends, like the CUDA C compiler front-end, can generate NVVM IR....
Either separate compilation (--relocatable-device-code=true or --device-c) or extensible whole program compilation ( --extensible-whole-program ) must be enabled. Generated PTX must be linked against the CUDA device runtime (cudadevrt) library (see Separate Compilation). Example: Dynamic Para...
This example adds two doubles together in the GPU. The CU code to do this is as follows. __global__ void add1( double * a, double b ) { *a += b; } The directive__global__indicates that this is an entry point to a kernel. The code uses a pointer to send out the result in...
