#WINRAR VS WINZIP ZIP#

And I haven’t seen any previous threads discussing zip type compression algorithms in CUDA. I believe someone pointed out on the first page that you could split a big stream into many sections and compress them all separately in parallel which then digressed into texture caches and then finally got on to Larrabee… Still, no one here is going to do all your homework for you. Assuming you can do the compression on the GPU, the PCIe transfers are likely to be a big bottleneck.Īre you compressing many independent streams at once, or just one big stream? Thousands of streams in parallel could be done in CUDA without too much trouble. But I’ll start with a few questions to get you thinking about where some bottlenecks might be.Ĭorrect me if I’m wrong, but aren’t file compression routines basically disk I/O bound? What gain would you hope to see using CUDA? Or are you thinking of speeding compression on data that is already in memory? In this case, you are going to be limited by the PCIe bandwidth: copying the data out to the GPU and back again at ~4 GiB/s. I’m no expert in file compression myself, so I can’t offer you any great ideas on putting it on the GPU off the top of my head. Unfortunately, tmurray is the closest thing we have to a moderator right now, and he was participating in the discussion on Larrabee External Media
