Are there any compression programs (e.g. gzip, 7zip, xz) that can use GPUs to accelerate compression? I've been playing with a 5.7 GB qcow2 image of an OpenStack instance, and with xz using extra options I could get the file compressed to only 1.6 GB, but it took almost 2 hours to get that, compared to ~10 minutes when the compressed file size was 4.5 GB. It got me to wondering if any programs use GPUs to speed it up. I saw some discussion around NVIDIA's CUDA library (Compression library using Nvidia's CUDA). Has anything been developed since then?

Well, there is new WinZip, uses GPU by OpenCL. You need to test to see if is good to you.
