...mation that I think may be pertinent to solving the problem. The following is therefore a bit lengthy, but I think complete (as far as I'm able to tell from the existing documentation). It's organized into sections roughly by the topic tested.

...ent to snow. Also uses MPI underneath. - Rmpi: Probably. Should definitely work for my needs, only question is if it's the best choice. Is it stable, complete, robust, etc.? - rpvm: Maybe. Should be equivalent to Rmpi, but MPI is much more popular on clusters than PVM these days. - NetWorkSpaces: Maybe. This looks like a rather mature and well-supported multi-language TupleSpace implementation, so it could certainly be made to work. Passing all my large R data objects back and forth solely as strings seems very unappealing, but the docs hint that it includes direct (or at leas...

...a notice that the server is migrating. Has this work been discontinued? Anyone using this? I see RScaLAPACK is still available, from reading the above it seems that was bundled with taskpR. Does it function without the other components? (Guess I'll try it and find out :) C. Sleigh & "NetworkSpaces" I see that SCAI (Scientific Computing Associates) offers a parallel R package based on something they call NetworkSpaces and "Sleigh" (inspired by Snow). They sell services around the product but it is open source. They have an enhanced version that they sell & support. http:/...

Hi all I am trying to backup via ssh the complete contents of a hard drive, but I'm running into some trouble. The source is an ext3 drive on an Ubuntu 9.10, and contains various files with sizes ranging from several KB to 5GB to a total of approximately 250GB. The source is a modified LaCie NetworkSpace 500GB on which I've opened a new root user and installed tools such as ssh and

Hello, The problem I'm working now requires to operate on big matrices. I've noticed that there are some packages that allows to run some commands in parallel. I've tried snow and NetWorkSpaces, without much success (they are far more slower that the normal functions) My problem is very simple, it doesn't require any communication between parallel tasks; only that it divides simetricaly the task between the available cores. Also, I don't want to run the code in a cluster, just my...

...(e.g. mclust). REvolution Computing developed all of the code in ParallelR (except for the bundled GPL packages Stephen mentions), and we decided to release it under our own license in REvolution R Enterprise. That said, we do already release components of parallelR, such as the underlying engine, Networkspaces (also written by REvolution Computing) under an open source licence. Also, we are likely to release some other components including foreach and iterators, to CRAN soon.

Hi, everybody. Sorry to bring up the subject again but I have visited the revolution computing web page, but its not clear when or what will be the new release be. Does anybody have information about that?. Does anybody know if the version that will be released will be validated?. I have been reading the previous mails about validation and I work in a Pharma company and validation is a big

Version 2.2.0 of package bcp is now available. It replaces the suggests of NetWorkSpaces (previously used for optional parallel MCMC) with the dependency on package foreach, giving greater flexibility and supporting a wider range of parallel backends (see doSNOW, doMC, etc...). For those unfamiliar with foreach (thanks to Steve Weston for this contribution), it's a beautiful and h...

Hello, We have created an interface between R and Hadoop so that the user can, after a fashion, interact with very large datasets using the Map Reduce programming model. We also use IBM's TSpaces to implement a shared memory implementation that can be accessed via R(somewhat like networkspaces). RHIPE uses Rserve to execute R code. Some of the functions implemented are: mrlapply - run lapply across a Hadoop cluster mrsubsetf - subset a file according to an R function mtapplyf - run a tapply on a file - mrmapreduce - run a map reduce algorithm on a file or group of files. The user p...

Dear all, I usually run R on my laptop with Windows XP Professional. Now I really want to run R on a computer cluster (4 processors) with Suse Linux Enterprise ver. 10. But I am new with computer cluster. Should I modify my functions in order to use the greater performance and availability than that provided by my laptop? Is there any R manual on parallel computations on

Hello dear R-help group (and David Smith from REvolution), I would like to perform parallel computing using R with Condor (hopefully using foreach or other recommended solutions, if available) for some "Embarrassingly parallel" problem. I will start by listing what I found so far, and then go on asking for help. So far I found the a manual by Xianhong Xie from Rnews_2005-2 (see page

Guys, I'm running R on both Windows & Linux. I'm looking at a number of packages for parallel execution. It seems that the most used packages are "snow" and "Rmpi". snow seems more user friendly, but it doesn't run on windows. I see from searching the mailing list that I'm not the first one to try it on Windows. There was a message that kind of shed some

Howdy all... Reading with interest the thread(s) about REvolution, package licensing and the requirements of the GPL. First of all, let me introduce myself?. ?I joined REvolution Computing in February, after working for nearly 4 years for Intel as an open source strategist and before that for 6 years at Sun, where I established the first corporate open source programs office. ?I'm a Member of
