2 GB at the start

Just entering the main() in a program linking to "openblas" under MSYS2 consumes 2 GB of RAM.
VMMap shows it as 16 blocks 128 MB each. Are these allocations necessary? Can they be postponed to when I really need something from OpenBLAS?

Setting these variables reduces the memory to 600 MB. It looks like 128 MB is allocated per thread in DLLMain

set OPENBLAS_NUM_THREADS=4
set GOTO_NUM_THREADS=4
set OMP_NUM_THREADS=4

This does not help either:
openblas_set_num_threads(1);

The original issue was against libllama: https://github.com/ggml-org/llama.cpp/issues/18024

Riproduci il comportamento all’avvio in MSYS2 entrando in main() in un programma collegato a OpenBLAS e ispezionando le allocazioni con VMMap. Confronta le impostazioni predefinite dei thread con OPENBLAS_NUM_THREADS, GOTO_NUM_THREADS, OMP_NUM_THREADS e openblas_set_num_threads(1). Il lavoro è completato quando si determina se le allocazioni di 128 MB per thread di DLLMain sono necessarie o possono essere posticipate.
