@jaber23 Cycle accurate emulation feels powerful. How do you keep performance overhead low? Maybe lightweight modes could help.

@masump we're ptx-based, ptx simulation is inherently fast while still giving you cycle-accurate insights across architectures

@istiakahmad that's why we build it:D

This look great!

@malithmcrdev thanks!!

Does it help identify memory bottlenecks automatically, or do I still need to hunt them down?
Being able to leverage local LLMs for coding more efficiently is awesome.
Huge congrats on shipping this.
“GPU-native” editor + real-time profiling + H100 emulation in one place feels like a massive DX upgrade vs juggling Nsight + scripts + docs.
Really curious to see how close the emulator gets to real hardware in practice.

@patch_app Thanks Tomo<3
GPU emulation is notoriously slow. How close is your emulator’s behavior to real hardware, especially for warp scheduling and memory access patterns?
This is solving such a critical pain point in GPU development. The 98% accuracy emulator + real-time profiling combo is genuinely powerful.
Question: What's your user acquisition strategy? Are you targeting individual CUDA devs or enterprises with large-scale GPU infrastructure? Also curious about pricing model - per license or cloud-based consumption?
Love the focus on developer UX for a niche but growing market. Great execution! 💪
