Hi,
How to check triton selected which config from the list I provided?

thanks for you help in advance

Solved, i printed out the self.best_config in triton/python/triton/runtime/autotuner.py#L107.

Hi, I am going through the triton tutorial on matmul (https://triton-lang.org/main/getting-started/tutorials/03-matrix-multiplication.html#sphx-glr-getting-started-tutorials-03-matrix-multiplication-py), looking for the best_config. Could you elaborate where could I find the Autotuner object to print best_config? I tried the following but didn't work.

kernel = matmul_kernel [grid] (a, b, c, # pointers 
              a_rows, a_cols, b_cols, # size, 
              a.stride(0), a.stride(1), # strides 0: is the highest dimension
              b.stride(0), b.stride(1),
              c.stride(0), c.stride(1))

kernel.best_config.

Thank you!

Should be matmul_kernel.best_config

From readme.md hh

TRITON_PRINT_AUTOTUNING=1 prints out the best autotuning config and total time spent for each kernel after autotuning is complete.
