We just released a new challenge today ❗ GPT-2 (120M) Transformer Block Compose multiple kernels into a full transformer block. The first of many upcoming challenges focused on real-world inference optimization. Write your solution in CUDA, Triton, PyTorch, JAX, Mojo, or CuTe DSL and benchmark it on state-of-the-art GPUs like the H100, H200, and B200, and more.

@vikhyatk @sasuke___420 @JohnThilen @willccbb Leetgpu is disappointing. Tensara is actually quite good but could use far more problems. How they score Leaderboards is a bit iffy though.

@sasuke___420 @JohnThilen @willccbb there's no good one for gpus, someone has to make one i did leetgpu for a bit. gpu mode also hosts contests. but really just go and make vllm a little faster

Sorry, I just can't take any programming language seriously that teats unused variable, or unused import, as a hard error. Such a nightmare to prototype in. Feel free to use them if you like fake feeling of being productive when you comply with the linter.

How it feels trying to keep up with feature requests for @LeetGPU
tetsuo.cpp (no slop)@tetsuo_cpp

Oh, you're writing CUDA kernels? Everyone's on Triton now. Just kidding, we're all on Mojo. We're using cuTile. We're using ROCm. We have an in-house DSL compiler targeting the NVGPU MLIR dialect but wait, Tile IR just dropped so we're going to target that instead. Our PM is on TileLang. The team lead was on CuTe but now she's back to handwriting PTX. If you're not on Pallas, you're ngmi. Our intern is building on TT-Metalium for our Wormholes. Our CFO approved an order for some big chungus wafer-scale chips so now we're porting our kernels to CSL. Our CTO is working on a kernel-less graph compiler so we won't need to write kernels anymore. Our CEO thinks we're talking about the Linux kernel. We're building Claude for dogs.

I wired up a tiny actor runtime in Go, pumped 10M messages through it, and got ~30M ops/s. It’s not production-stable yet, but the pattern feels right. In Go, the actor model is simply: “one goroutine owns some state, and you only touch that state by sending it messages over a channel.” No locks, no shared mutable state, no random goroutines poking into your structs. --- Core idea - Each actor = 1 goroutine + 1 mailbox (chan Msg) - Actor has private state inside the goroutine - Other parts of the program never access that state directly – they just Send(msg) - The actor loops forever: for msg := range inbox { handle(msg) }

I'm sold on the actor model. After some struggling, finally cracked it. This is the max, It's not stable but stable enough and it gives a good feeling :-). [test_throughput_actor_model] total_messages=10000000, iterations=1, elapsed=0.334s, throughput=913.88 MiB/s, ops=29.95 M ops/s (min=29.95, max=29.95)

When querying databases in Go, use & with rows.Scan() to pass addresses, not values. Scan() needs to write directly into your struct fields. From my Build Your First Go App course...follow for updates

@0xlelouch_ Use a WaitGroup instead of a done channel

Nice. Let me share a small go function to understand language semantics. Backpressure and coordination using channels. Channels are not just for passing data The jobs channel also slows down the producer because it has a buffer of only 2. If workers fall behind, the producer blocks. That’s backpressure for free! Goroutines scale downward just as cleanly as upward You launch a few workers and the language handles all the scheduling for you. No mutexes, no condition variables. Completion coordination is trivial The done channel lets main wait for all work to complete without any complex thread management.

where should I go after leetgpu? I just did my first 3 problems and I'm thinking another implementation of mnist might be a good next step
