...doing the same stuff using bootstrapped data, so for the original there is more data and I show the arithmetic mean with standard deviation. The confirmation with the patched R was only a single instance of that series of jobs. ## Job Efficiency The job efficiency is defined as (this is what the `qacct-efficiency` tool below does): ``` efficiency = cputime / cores / wallclocktime * 100% ``` In simpler words: how well did the job utilize its CPU cores. It shows the percentage of time the job was actually doing stuff, as opposed to the difference: ``` wasted = 100% - efficiency ``` ... which, e...

Dear R-Devel List, **TL;DR:** The function **parLapplyLB** of the parallel package has [reportedly][1] (see also attached RRD output) not been doing its job, i.e. not actually balancing the load. My colleague Dirk Sarpe and I found the cause of the problem and we also have a patch to fix it (attached). A similar fix has also been provided [here][2]. [1]:
