Hi all, Henrik Bengtsson has done some fantastic work with {future} and, more importantly, greatly improved constructing and deconstructing a parallelized environment within R. It was with great joy that I saw Henrik slowly split off some functionality of {future} into {parallelly} package. Reading over the package?s README, he states: > The functions and features added to this package are

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

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)

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.

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. Error: unprotect_ptr: pointer not found Error: argument to 'findVar' is not an environment

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",

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

Dear XAPIAN developers, I was using xapian to index large than 13 million document about Q & A(Quora similarly). I will share some performance data about indexing and searching, and I will seek some help for improving performance of searching. My computer has 8 i7 at 3.4G CPU and 16G memory, ubuntu 16.04. Dataset include about 13M document, each document will be cut into 35 term(Chinese

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

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

Hello, I am trying to see if the hypervisor can be used to detect deadlocks in the guest VMs. My goal is to detect if a guest OS is deadlocked, and if it is, then create a clone of the deadlocked OS without the locking condition, and letting the clone run. While the clone runs I am hoping to generate some hints that could tell me what caused the deadlock. I simulated a deadlock/hang

I met with the Propeller team today (we work for the same company but it was my first time meeting two members on the team:) ). One thing I have been reassured: * There is no general disassembly work. General disassembly work would assuredly frighten off developers. (Inherently unreliable, memory usage heavy and difficult to deal with CFI, debug information, etc) Minimal amount of plumbing work

Guys, I''m designing an application currently that will ultimately be implemented in either Rails or php5 (most likely Rails). While I''ve coded many PHP (pre-5) applications in the past, OO support was so weak that my OO designs were never truly divorced from the limitations of the language, thus I never had to consider this problem. The question is: how does Rails (and how do
