- Add mpi_stub.h providing all MPI types/constants/functions as no-ops (nprocs=1, myrank=0) with memcpy-based Allreduce and clock_gettime Wtime - Replace #include <mpi.h> with conditional #ifdef MPI_STUB in 31 files (19 headers + 12 source files) preserving ability to build with real MPI - Change makefile.inc: CLINKER mpiicpx->icpx, add -DMPI_STUB to CXXAPPFLAGS - Update makefile_and_run.py: run ./ABE directly instead of mpirun -np N - Set MPI_processes=1 in AMSS_NCKU_Input.py Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
