리눅스에서 명령어를 가지고 아키텍처 식별방법
CPU 아키텍처는 물리적 소켓/ 프로세서 갯수, 프로세서당 코어갯수, L1/L2/L3 Cache, NUMA(Non-UNIFORM MOMORY ACCESS) 구성등이 해당됩니다.
총 6가지 방법으로 정리하였습니다.
# git clone https://github.com/rrze-likwid/likwid.git
# cd likwid
# make ; make install
# likwid-topology -g
likwid-topology: Display the NUMA and cache topology.
likwid-perfctr: Display the hardware performance counters of processors.
likwid-features: Display and change hardware prefetch control bits on Intel Core 2 processors.
likwid-pin: Pin a multi-threaded application to a specific CPU.
likwid-bench: Benchmarking tool for rapid prototyping of threaded assembly kernels.
likwid-mpirun: script enabling CPU pinning of MPI and MPI/threaded hybrid applications.
likwid-perfscope: Frontend for likwid-perfctr which allows real-time plotting of performance metrics.
likwid-powermeter: Tool for accessing RAPL counters and query Turbo mode steps on Intel processor.
likwid-memsweeper: Tool to clean up ccNUMA (cache-coherent NUMA) memory domains.
