When I am trying to call the function:
dim3 grid(300, 300 , 1);
dim3 threads(1024, 1024, 1);
hashScan_cuda2<<< grid , threads>>>
the code dosnot work, But when I trying to run:
dim3 grid(300, 300 , 1);
dim3 threads(1024, 1, 1);
hashScan_cuda2<<< grid , threads>>>
The code runs well.
2) how can I run the:
Max dimension size of a thread block (x,y,z): (1024, 1024, 64)
Max dimension size of a grid size (x,y,z): (2147483647, 65535, 65535)
- And what is and how to do it?
(multiple host threads can use ::cudaSetDevice() with device simultaneously)
