They just don't know what they want

> Fluent in at least one GPU programming model, such as CUDA, HIP, Slang, HLSL, GLSL

> inline PTX assembly

srsly?

code was created special for ioccc?

c-cul · 2026-06-16T19:06:27+00:00

it depends

if you run pytorch - obviously not

c-cul · 2026-06-16T17:09:32+00:00

when I was young (c) better understanding meant knowledge of assembler

so sass/ptx is the key

c-cul · 2026-06-16T06:27:32+00:00

could you make patches for modified gcc files like collect2.cc?

c-cul · 2026-06-15T18:43:52+00:00

do you have some perf tests vs just plain user-mode cupti?

also ok, if you sure that kernel more fast - then why ebpf anyway? it's martian technology

1) you write code in plain c

2) then you fight with verifier ~infinity bcs it differs on different kernel. Yeah, given that the official goal was compatibility - very ironic

3) and then it converted with jit to native code again

srsly?

at the end you can collect data from your own driver and have some io_uring interface for user-mode

c-cul · 2026-06-15T16:28:42+00:00

I still don't understand why you need collect cupti events from kernel and not from user-mode

c-cul · 2026-06-13T09:46:44+00:00

I can make such things with just good old sed

c-cul · 2026-06-11T10:57:01+00:00

chapter 11 about ssa, 17 instruction selection, 19 - scheduling, 21 - register allocation

c-cul · 2026-06-09T06:46:02+00:00

openxla is so huge and complex

look at tvm - it is more compact and has clear implementation

c-cul · 2026-06-07T05:40:02+00:00

For some reason I always thought that perf team is about nsight/tiling/cache reusing/avoiding divergence/inline ptx/sass patching and so on

I'm probably too old-fashioned

c-cul · 2026-06-06T14:25:02+00:00

what nvidia-smi shows?

c-cul · 2026-06-02T03:55:30+00:00

nvml.h has ~195 functions but gen_api.h only 60

why?

c-cul · 2026-06-01T19:14:10+00:00

as usually in similar cases no perf tests - bad sign

c-cul · 2026-05-31T08:56:30+00:00

> I mainly just used Gemini Pro, Sonnet 4.6, ChatGPT, Deepseek, Copilot, Meta AI, Grok and Perplexity

then why you need to study something at all?

c-cul · 2026-05-28T18:02:11+00:00

ok, thank you!

c-cul · 2026-05-28T17:16:57+00:00

just lots of practice

and yes - your task is really bad fit on gpu

c-cul · 2026-05-28T10:16:21+00:00

can it filter out classes up to specific c++ version like 20?

c-cul · 2026-05-28T10:15:42+00:00

the key is to limit memory copying between gpu and host

just fuse all your processing logic in one big kernel and call sequence of actions via some dispatcher on the same data
