Hi, this is the first time I write in this forum. I’m Alessandro, an italian student of computer engineering. I have a little problem
when I do this:
block_size = 128;
int num_block = t/block_size;
Search<<<dimGrid,dimBlock>>>(da, da2, p_res, lun_par);
When “t” is a relatively small number (then also num_block is a small number), like 10000, 20000, but also 100000, it works well.
but when it is for example 10 millions, the gpu do not generate 10millions/block_size blocks but less!
Why? There is a limit in the number that I can pass to dimGrid()???
