Responded to a request to run 07_gemm_all_scatter across 10 GEMM shapes. The sandboxed Copilot agent environment lacks AMD GPU/ROCm access required to execute the benchmark, so no results could be produced directly.

Replied with a ready-to-use shell loop covering 10 representative GEMM shapes (varying M/N/K from 4K–16K), runnable once the self-hosted ROCm runner is active:

for shape in \
  "4096 4096 4096" "8192 4608 36864" "4096 8192 8192" \
  "16384 4608 36864" "8192 8192 8192" "4096 4096 16384" \
  "8192 4096 16384" "16384 8192 16384" "4096 16384 4096" \
  "8192 16384 8192"; do
  read M N K <<< $shape
  python examples/07_gemm_all_scatter/benchmark.py -m $M -n $N -k $K -r 2 --benchmark
done
