GPU Meeting: FFTs
Larne Pekowsky (CRA)
- CUDA FFT is a drop-in replacement for FFTW. Because of the memory bandwidth, CUDA is faster above 2^14 element FFTs in 1D. Tested on GTX 580.
- Used in LIGO data analysis.

Lionel London (CRA) – GPU Computing in Matlab
- Matlab Parallel Computing Toolbox (PCT) vs. Jacket
- PCT allows for multi-cpu and GPU computing. Limited to 12 cores on the local machine. Very high level.
- GPU computing with PCT requires an nVidia card with v1.3 compute capabilities. GPGPU with Jacket has relaxed requirements but is very expensive ($4k for 5 … Continue Reading ››

Matt Kinsey: Porting the 2D Wave Equation to the GPU
- Optimal number of threads per block is 32*n-1, where n is an integer. The best performance in the example shown was 63 threads per block.
- Minimum number of blocks per grid is 32, according to the user's guide.
- Every time a kernel is called, the memory needs to … Continue Reading ››
