[parallel] fixes load balancing of parLapplyLB
Hi, I'm trying to understand the rationale for your proposed amount of
splitting and more precisely why that one is THE one.
If I put labels on your example numbers in one of your previous post:
nbrOfElements <- 97
nbrOfWorkers <- 5
With these, there are two extremes in how you can split up the
processing in chunks such that all workers are utilized:
(A) Each worker, called multiple times, processes one element each time:
> nbrOfElements <- 97
> nbrOfWorkers <- 5
> nbrOfChunks &...

[parallel] fixes load balancing of parLapplyLB
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].
