gpu programming



  • I figure this isnt a bad place to ask about gpu programming. I’m working on some massively parallel programing that i’d like to port to the amd chipset to distribute the work (cuda would work but i have lots of amd cards so… yeah) . I did a bunch of googling last night and it looks like more c# programmers (which i am) use a wrapper on the c++ amp.

    can anyone give any advice for an easy how-to place to go to get some sample code and get started. anything i need to know? i saw something about pointers being a being off limits in the kernel process you pass in. i’m guessing changing the classes and their code to structs is fine. right? or is that even a real limitation.

    GPU programming is a rare skill, worth developing. The few people I’ve chatted to doing it keep things to their chest. Wolf has done a lot of good programing, kernels for mining on GPUs, if you see him around.



  • Yeaaa, so I work in a warehouse and I’d like to know if that was even English you spoke there.

    good luck though, it sounds like you’re trying to do more than bios mods on them.



  • @lcr11 it actually has nothing to do with cryptocurrency mining. i was working on a data mining thing (not even remotely related though they both say “mining” in them) and just want to go really wide with it.



  • I figured out everything i needed. the short version is I’m going to use/got working a sample of openCL . (I tested a local build on different machines each with 2 different graphic cards and all seems to work well)

    The long version check out this link https://www.codeproject.com/Articles/1116907/How-to-Use-Your-GPU-in-NET you will also need to install intel’s opencl and the latest graphics drivers on the machines you are working on. The final code seems to actually be a script that is compiled at runtime and sent in to the graphics cards. it worked on nvidia and 7990 (2 gpus) and R9 series amds so… seems to work quite well.
