《CUDA by Example》--chapter10 code 先来介绍CUDA中的一个函数:cudaHostAlloc(),理解这个函数,要和标准C语言中的malloc()联系起来。malloc()函数是CPU在主存中开辟内存并返回指针,而cudaHostAlloc()是cuda在主存中开辟指定内存并返回指针。cuda开辟和CPU开辟的主存有什么不同?CPU是分配可分页的(Pagable)主机内存...
p.23,25 - The #includes for this example are incorrectly shown as: #include <iostream> and #include "book.h." This has been corrected in the downloadable code package, but should read: #include <stdio.h> and #include "../common/book.h" ...

char* __cu_demangle(const char* id, char *output_buffer, size_t *length, int *status) The following C++ example code shows usage: #include <iostream> #include "/usr/local/cuda-14.0/bin/nv_decode.h" using namespace std; int main(int argc, char **argv) { const char* mangled_name ...
The libdevice library is an LLVM bitcode library that implements common functions for GPU kernels. NVVM IR 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 fr...
# Above this line, the code will remain exactly the same in the next version if tid == 0: partial_c[cuda.blockIdx.x] = s_block[0] # Example 4.6: A full dot product with mutex @cuda.jit def dot_mutex(mutex, a, b, c): ...
The following code sample creates two streams and allocates an array hostPtr of float in page-locked memory. Each of these streams is defined by the following code sample as a sequence of one memory copy from host to device, one kernel launch, and one memory copy from device to host: ...
Either the –arch or –generate-code option must be used to specify the target(s) to keep. All other device code is discarded from the file. The targets can be either a sm_NN arch (cubin) or compute_NN arch (ptx). For example, the following will prune libcublas_static.a to only ...
