ttsem

Runs Triton kernels from their IR on the CPU and checks every launch (races, out-of-bounds, per-pass validation). Found silent torch.compile miscompiles without a GPU.

Run the tests of your Triton kernels on a machine with no GPU and get the faults a GPU run hides: a write past the end of a tensor, two program instances that touch the same element with at least one of them writing it, an operation with an undefined result. Each one fails its test at the line of your kernel. Memory nobody wrote is filled with NaN instead, so a read of it shows up in the values. ttsem compiles every launch with Triton's own frontend and executes the IR it produces on the CPU.
