Are there plans to develop a GW search CUDA application?

Hi all,

I would like to ask whether there is any CUDA GPU application for the gravitational waves search being under development, or whether there are any plans to develop it in the future. (If I understood it correctly currently there is only the Arecobo Binary Pulsar search CUDA application).
I know that for ABP search there are some inefficiencies caused by the GPU memory architecture/allocation - would it be also the case with the GW search algorithm? Or is the GW search algorithm completely unsuitable for GPU calculations?

Thanks for answers.

I don't know but the GW search app uses hand-optimized assembler-code. I believe a GW search CUDA app would have the inefficiencies too.

Actually we did make a CUDA

Actually we did make a CUDA app for S5R6. The problem is just that with the current algorithms this isn't any faster than running on the CPU.

For the next run that should start right after S5R6 (about three months left) we're working on a new, faster application that will perform better on GPUs (and CPUs, too).

Thanks Bernd for the information and also for your responsiveness, both are encouraging.
I'll keep my fingers crossed that the new GPU app is faster and will contribute to enhance project's computing power.
