- 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>

## CPU core binding configuration using taskset
|
|
## taskset ensures all child processes inherit the CPU affinity mask
|
|
## This forces make and all compiler processes to use only nohz_full cores (4-55, 60-111)
|
|
## Format: taskset -c 4-55,60-111 ensures processes only run on these cores
|
|
#NUMACTL_CPU_BIND = "taskset -c 0-111"
|
|
#NUMACTL_CPU_BIND = "taskset -c 16-47,64-95"
|
|
NUMACTL_CPU_BIND = "taskset -c 8-15"
|
|
|
|
## Build parallelism configuration
|
|
## Use nohz_full cores (4-55, 60-111) for compilation: 52 + 52 = 104 cores
|
|
## Set make -j to utilize available cores for faster builds
|
|
BUILD_JOBS = 96
