Embodiment 1
[0063] By applying the access control method of the concurrent queue access control strategy PDACS in the parallel platform Cilk of shared memory multiprocessors, and making a comparative experiment with the original Cilk parallel platform, the experimental test set adopts the standard test set of MIT Cilk, and the experimental environment platform is a An Inspur server with an intel xeon phi 7110P series processor has a total of 61 processor cores. After enabling CPU hyperthreading, it has a total of 244 logical processor cores, which can support concurrent execution of 244 physical threads. Server operation The system is RedHat Linux 6.3.
[0064]Use the MIT Cilk test program to test the execution time of the test program on the Cilk parallel platform and the PDACS parallel platform under 244 threads respectively. The compiler used when compiling the test program is For C++ Composer XE 2013 SP1, the compile-time optimization level option is -O2. The test results show that t...
