v3.0

Visualizers are fun, but sometimes debugging kernels requires more than looking at tensors... We rewrote the architecture of Triton-Viz to support new analysis clients and DSLs!

On top of the visualizer, we've added two new analysis clients:

• Profiler: Flags performance hazards like non-unrolled loops, inefficient mask usage, and missing buffer_load optimizations.
• Sanitizer: Symbolically checks tensor memory accesses for out-of-bounds errors.

Just add one decorator and pick your client:

@triton_viz.trace("tracer")
# OR
@triton_viz.trace("profiler")
# OR
@triton_viz.trace("sanitizer")

In addition, we added experimental AWS NKI support so you can debug Trainium kernels with just your CPU.

See the examples folder to see how to run your own kernels.
