《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...
The following code example shows how runtime JIT LTO can be used in your program. Generate NVVM IR usingnvrtcCompileProgramwith the-dltooption and retrieve the generated NVVM IR using the newly introducednvrtcGetNVVM. ExistingcuLinkAPIs are augmented to take newly introduced JIT LTO options to a...

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: Each stream copies its portion of input array hostPtr to array inputDevPtr in device memory, processes inputDev...

If this code was put in the same CU file along with the code of the first example, specify the entry point name this time to distinguish it. k = parallel.gpu.CUDAKernel("test.ptx","test.cu","add2"); Before you run the kernel, set the number of threads correctly for the vectors ...
1.6. CUDA 5.5 ‣ Linux makefiles have been updated to generate code for the AMRv7 architecture. Only the ARM hard-float floating point ABI is supported. Both native ARMv7 compilation and cross compilation from x86 is supported ‣ Performance improvements in CUDA toolkit for Kepler GPUs (...
