minor error in NVIDIA_OpenCL_BestPracticesGuide.pdf

Accelerated Computing CUDA CUDA Programming and Performance

Hi,

I’m not sure if its the right place to inform about errors in documentation - anyway I haven’t found an email for error reporting.

In NVIDIA_OpenCL_BestPracticesGuide.pdf, page 26, Listing 3.9:

[codebox]

aTile[y][threadIdx.x] = a[row*TILE_DIM+x];

bTile[y][threadIdx.x] = b[y*N+col];

[/codebox]

There’s no threadIdx in OpenCL - apparently code samples were translated from CUDA. This makes me wonder if performance tests of code snippets in documentation were performed with OpenCL or were just taken from CUDA…

You’re right I found the same when I read it.
It’s like a copy-paste problem…
