patch

Some modifications regarding PMI2 and PMIx plugins.These changes, mainly done by Hongjia Cao (the original author of the PMI2 plug-in) and Yiqin Dai, reduce the PMI2 plug-in failures when running large scale jobs and reduce the time overhead steps in the PMIx plug-in. One of the changes to the PMI2 plug-in is proposed to be added to the official release.


This is a problem found by the National University of Defense Technology when applying slurm to large scale supercomputers (over 10^6 cores), and we classify the problem into five categories, of which the above problem is one.We provide a simpler patch and look forward to communicating with and contributing code to the Slurm community.  The authors of this patch are Hongjia Cao and Yiqin Dai at daiyq@nudt.edu.cn.
