Process to Incorporate Functions from {parallely} into base R's {parallel} package
FWIW, there are indeed a few low hanging bug fixes in 'parallelly' that should be easy to incorporate into 'parallel' without adding extra maintenance. For example, in parallel::makePSOCKcluster(), it is not possible to disable SSH option '-l USER' so that it can be set in ~/.ssh/config. The remote user name will be the user name of your local machine and if you try to

Process to Incorporate Functions from {parallely} into base R's {parallel} package
If these are easy changes, maybe someone will incorporate them. You'll make the argument stronger for doing that if you can explain why it's better to do that than to keep them in parallely.

Parallel R expression evaluations
Hi all, I am using R-3.0.1 under Linux platform to embed R into my C++ code. I am facing an error while executing more than 1 R-expressions parallelly. I am executing round(X) and abs(X) parallelly on a set of 50 input rows which resulted in segmentation fault after getting the following errors.

Packages sometimes don't update, but no error or warning is thrown
Hey everyone, Thanks for all the input. It's happening again. This time for the packages "DBI", "parallelly", "segmented", "survival", "V8". So, RStudio shows updates for those and updating them via RStudio leads to this output: ``` > install.packages(c("DBI", "parallelly", "segmented", "survival",

How to add points to two plots parallelly ?
I am looking for ways to add points to three different plots in parallel. I generate three scatter plots and name them as s3d1, s3d2 and s3d3 s3d1<-scatterplot3d(mtcars[,3],mtcars[,4],mtcars[,5],main="common",pch=20) s3d2<-scatterplot3d(mtcars[,3],mtcars[,4],mtcars[,5],main="common",pch=20)

Regarding Issue Running Parallel Computing on Linux RHEL version 8
Hi Team, I am writing to bring to your attention an issue we have encountered following the recent update of our Linux server from RHEL 7 to RHEL 8. We have an R script designed to create demand forecasts utilizing parallel computing on the Linux server. Before the version update, the script executed successfully within approximately two hours. However, since updating to RHEL 8, the script has

Parallel computing: how to transmit multiple parameters to a function in parLapply?
Hi R-developers In the package Parallel, the function parLapply(cl, x, f) seems to allow transmission of only one parameter (x) to the function f. Hence in order to compute f(x, y) parallelly, I had to define f(x, y) as f(x) and tried to access y within the function, whereas y was defined outside of f(x). Script: library(parallel) f <- function(x) { z <- 2 * x + .GlobalEnv$y # Try to

I am currently using R-2.3.1, and Cygwin to run R on Windows xp. ssh and all are working fine, When I try to create a socket connection as makeSOCKcluster(c("localhost","localhost")), it just waits for the other prcess on localhost to get created and respond.

I feel like I may be one or two non-obvious steps away from getting it all working, but I'm stuck. If anyone can shed some light on this (I believe Prof. Tierney stated that he has successfully run a

Opening more than 1 R console in Windows
Hi all, I recently found out that R does not utilize fully the Duo Core capability when you only run one instance of R. I did some number crunching today and it seems that if I only open 1 R console, it uses 50% of my CPU (either 50-50 or 100-0 on 2 cores). Then, I open the second instance and divide the work into two parts, and run them parallelly, they seems to utilize 100% of my CPU. So, my

[LLVMdev] [RFC] Parallelization metadata and intrinsics in LLVM (for OpenMP, etc.)
Hi, Sorry for the hiatus, busy time at my university. :) After a false start and some (hopefully cogent) thought, I am now of the opinion that it will be better to have llvm natively support a somewhat different notion of parallel computation and have the frontend lower OpenMP directives (and possibly other such things) into the same. In short, I propose a intrinsic based approach which hinges

static pdf vignette
Dear all, In my package I have a computational expensive Rnw file which can't pass R CMD check. Therefore I set eval=FALSE in the Rnw file. But I would like to have the pdf vignette generated by the Rnw file with eval=TRUE. It seems to me a static pdf vignette is an option. Any suggestions on this?

Another issue using multi-processing linear algebra libraries
I also have this questions for this. I wonder if R initiates a system environment or options to instruct the packages on the number of cores to use? It doesn't have to be mandatory for now, but at least package maintainers can have shared consensus and start to adopt this humble settings rather than abusing parallel::detectCores() to max out the number of threads by default. > On Aug 7,

long vector support
All, At first glance, a recent commit to R-devel ( https://github.com/wch/r-source/commit/2c182014ecc8c2407a89092c9162d86046bd18da) appears to be related to long vector support. But as Henrik Bengtsson points out at https://github.com/HenrikBengtsson/Wishlist-for-R/issues/97#issuecomment-562659134, writeBin() still prohibits long vectors. Are there any plans to add long vector support to R
