--restore-with-cpu=RESTORE_WITH_CPU
cpu type for restoring from a checkpoint
--gpu_core_config=GPU_CORE_CONFIG
configure the GPU cores like ['Fermi', 'Maxwell']
--total-mem-size=TOTAL_MEM_SIZE
Total size of memory in system
--num-dirs=NUM_DIRS
--clusters=CLUSTERS   Number of shader core clusters in the gpu that GPGPU-
