CUDA QUESTIONS

Allocate constant memory
Allocate constant memory
I wish this helpful for you Unfortunately the __ constant __ must be in the same file scope as the memcpy to the symbol, and in your case your __ constant __ is in a separate .cu file.The simple way around this is to provide a wrapper function in you

CUDA: cudaMemcpy only works in emulation mode
CUDA: cudaMemcpy only works in emulation mode
I wish this helpful for you You should check for errors, ideally on each malloc and memcpy but just doing it once at the end will be sufficient (cudaGetErrorString(cudaGetLastError()).Just to check the obvious:

Transferring data from CPU to GPU and vice versa where exactly?
I wish did fix the issue. The cudaMalloc function allocates a requested number of bytes in Device global memory of the GPU and gives back the initialised pointer to that chunk of memory. cudaMemcpy takes 4 parameters: Address of pointer to the destin

Can a new thread block be scheduled only after all warps in previous thread block finish?
Can a new thread block be scheduled only after all warps in previous thread block finish?
With these it helps No, more than one thread block can be scheduled on one multiprocessor if there are sufficient resources.Yes, TB0 and TB1 can be scheduled on the same SM, resources permitting - although I would not call that "by interleaving warps

CUDA: How many default streams are there on a single device?
Any of those help By default, CUDA has a per-process default stream. There is a compiler flag --default-stream per-thread which changes the behaviour to per-host-thread default stream, see the documentation.Note that streams and host threads are prog

Can CUDA store 8 unsigned char data in parallel
this will help Just expanding comments into an answer:Every older version of the compiler I tested (8.0, 9.1, 10.0) will emit two st.global.v4.u8 instructions in PTX (i.e. two 32bit writes) for the uchar_8 assignment at the end of your kernel. CUDA 1

What's the differences between the kernel fusion and persistent thread?
may help you . The idea behind kernel fusion is to take two (or more) discrete operations, that could be realized (and might already be realized) in separate kernels, and combine them so the operations all happen in a single kernel.The benefits of th
