Hi, I understand ShortRead::FastqStreamer will read chunks in parallel depending on the value of ShortRead:::.set_omp_threads I see this discussed here: https://stat.ethz.ch/pipermail/bioc-devel/2013-May/004355.html and nowhere else. It probably should be documented in ShortRead. Possibly this has already changed for I am using still R 3.1.0. I thought I'd check. Oh, and, in my

In pvec(list(1, 2), FUN, mc.cores=2) FUN sees integer() arguments whereas pvec(list(1, 2, 3), FUN, mc.cores=2) FUN sees list() arguments; the latter seems consistent with pvec's description. This came up in a complicated Bioconductor thread about generics and parallel evaluation https://stat.ethz.ch/pipermail/bioc-devel/2012-October/003745.html One relevant point is that a

Hello all, I upgraded my R workstation, and to my dismay, only one core appears to be used during intensive computation of a bioconductor function. What I have now is two dual-core Xeon 5160 CPUs and 10 GB RAM. When I fully load it, top reports about 25% user, 75% idle and 0.98 short-term load. The archives gave nothing helpful besides mention of snow. I thought of posting to HPC, but this system
