apparently nvidia only supports cuda on IBM power 8 like there's no opencl support for nvidia cards on power 8 systems

I'm working on making baby's first DNN using cuda ATM, and it sucks in some ways compared to opencl like I liked being able to pass kernel source to the opencl implementation and having it JITC'd and running. Instead I have to use NVCC, which doesn't work with fedora 26 cause the gcc implementation is too new, so i have a docker container with nvcc and gcc 6 installed just to compile ptx files to run in cuda

repiv posted:isn't this what you want it only works for ptx and such. i want to load a .cu file at runtime, and aside from calling nvcc at runtime to produce a ptx, it's not possible. edit: huh, looking at that documentation, it does very much seem to say you can load the cu and get a ptx file from it that you can then call with loadmodule. kinda strange the nvidia reps at the hpc conference i was just at didn't know about it.

you should definitely be able to, all the pre-compiling stuff is motivated primarily by being able to lock people out of your source code files and, if anything, complicates matters

repiv posted:isn't this what you want ok, i started compiling my kernel with nvrtc using a jnr binding i wrote and nvrtc is demanding 32 bit library includes?? edit: i think the rpm-fusion nvidia drivers and the nvidia repo cuda drivers were interacting weird. when i went to uninstall nvidia-driver.i686 (bye steam), cuda-9-0.x86_64 got pulled in too. likewise, installing cuda-9-0 pulled in the 32 bit drivers? disabling rpm-fusion seems to have fixed things... for now edit: i'm so loving dumb. i was getting errors like my gcc toolchain was missing cause.. it is! the loving nvrtc documentation says i cannot compile standard c programs with it, just CUDA KERNELS. and so i go ahead and feed it a cu file with an int main and stdio.h and spend the rest of the night scratching my head why this isn't working

so, i'm becoming less and less interested in using nvidia GPUs for computation right now. yeah, cuda's a nice lib, and yeah, i'd love to use power 8 for what we're doing, but apparently IBM power 8 with nvidia P100s only support cuda and don't support openCL at all. I'm not talking nvidia's typical, opencl 1.2 only support, they don't support vulkan, opengl, or opencl. just cuda. getting locked into a single vendors' computation platform seems like a big mistake, and it seems like nvidia is doing this all over the place (see: nvidia refusing to work with wayland, implementing their own dumb eglstreams thing that no-one uses)

there's sort of a technical justification for eglstreams but it's still kinda dumb something about being eglstreams being able to abstract out the format of scanout buffers so that the scanout buffer can be encoded in some proprietary pixel format or layout that reduces scanout power consumption idk

it is sort of weird since nvidia is setting themselves up with antitrust issues if they actually manage to stamp amd out of the running entirely, and that seems the way it'll end up i'm going to make an effort post on my pet interest in texture compression one of these days btw

Condiv posted:(see: nvidia refusing to work with wayland, implementing their own dumb eglstreams thing that no-one uses) nvidia is 100% of the linux graphics market that makes money so it would be more accurate to talk about wayland refusing to work with nvidia, instead supporting graphics primitives that exist only in little-used drivers

amd's newest pro driver has a feature where you can ''host" and toggle between up to two consumer radeon drivers. only works with wx and vega cards though, so no extreme gaming for me.

amd have the lead in the games market, playstation & xbox both use amd hardware. i guess that is a significant percentage of profit that nvidia can't touch. this has the knock on effect that unless it's a dedicated pc game, all time/money will be spent optimising shaders for amd hardware. pc performance is secondary - go buy a faster board if you want bigger numbers.

a quick google suggests that intel are the bosses of the gpus market from their integrated stuff, and they've started on a combined radeon/intel core for laptops. i wouldnt be surprised if long term, radeon becomes the default 'hi performance' integrated gpu for cheap mass market 'gaming rigs'

Remember that u.s. antitrust policy is driven by Bork doctrine, which states that as long as consumer prices are going down, monopolies are fine  This is why Amazon continues to be allowed to exist

Plenty of people out there running without discrete GPUs because they don't need them to shuffle windows around their desktop.
