GGML_ASSERT Failed During Benchmarking Dummy Model on Apple Silicon Mac.

Description

Error when running the llama-bench tool on a dummy model, as specified in readme. Failed assertion in ggml.c relating to tile number for parallel processing.

Steps to Reproduce

git clone --recursive https://github.com/microsoft/bitnet BitNetRecreate
cd BitNetRecreate
conda activate bitnet-cpp
python setup_env.py --hf-repo 1bitLLM/bitnet_b1_58-large -q tl1
python utils/generate-dummy-bitnet-model.py models/bitnet_b1_58-large \
    --outfile models/dummy-bitnet-125m.tl1.gguf --outtype tl1 --model-size 125M
python utils/e2e_benchmark.py -m models/dummy-bitnet-125m.tl1.gguf

Erroneous output

.../BitNetRecreate/3rdparty/llama.cpp/ggml/src/ggml.c:12696: GGML_ASSERT(ne0 % n_tile_num == 0) failed

Further Exploration

To diagnose, I added print statements after line 12695 of ggml.c. These showed that the ne0 value is as expected, but the n_tile_num value is 0, leading to the assertion error.

I tested with model sizes 125M and 350M. The only instance when the program doesn't crash is when creating a new model type '700M' with identical parameters to the original bitnet_b1_58_large model.

Comienza con los comandos de reproducción y ejecuta utils/e2e_benchmark.py con los modelos dummy generados de 125M y 350M en Apple Silicon. Inspecciona el cálculo del número de teselas alrededor de la línea 12696 de 3rdparty/llama.cpp/ggml/src/ggml.c y la invocación de llama-bench mostrada en el error. Se considera terminado cuando los benchmarks de los modelos dummy afectados se completen sin el fallo de GGML_ASSERT.
