摘      要：With the widespread utilization of multicore processors,operating systems face new challenges on *** lock mechanism used by current monolithic OSs makes some critical modules encounter performance bottlenecks caused by lock *** contention in Linux process lifecycle management results in process Creation,execution and termination(CET) scaling poorly with core count *** from the centralized fashion of Linux,this paper presents a Distributed process management model(DPMM) on microkernel for better *** kernel functions are distributed into message passing servers running on different *** splits the shared data including Process control blocks(PCBs),page pools and buffer caches into these cooperating *** actions including PCB creation/deletion,page allocation/freeing,executable loading and scheduling can be parallelized without *** micro-benchmarks show that DPMM achieves nearly linear performance growth on process CET and outperforms Linux and Minix3 on a 32-Core machine.
