[font=“Franklin Gothic Medium”]Hi Everyone,
GEFORCE GTX 465 NVIDIA Graphics CARD
PENTIUM CORE 2 DUO 64 Bit Processor.
I’m currently working on a Stereo Vision Algorithm. The basic steps are
- Upload the data
- Perform the computation
- Download the result
after downloading the result, I’m finding that the result is just “filled” with zeros.
So I’ve written a small snippet which allocates an array of size equal to the number of threads. Using memset(), i’m setting all the entries to “0”. In CUDA kernel, each thread just places it’s ID in the array location indexed by ID.
in other words, a thread with ID = “N” does this
array[N] = N;
But after downloading, the array is just filled with zeroes.
Please let me know, what could the possible cause.
Thanks for your time.
