similar to: foreach hangs when using doMPI on Windows with Microsoft MPI

hello all i am busy testing some code that will be used for parallel computations on a Moab cluster. I have written a C++ program and am linking it with R using the .C command - this works correctly. Extracts of the r code (as well as the *.sh file) is included below. I am able to run the code successfully if I remove all of the doMPI commands. i.e. outs=.C("prog1", all of the

Hi all, I'm trying to use a parallel script on a 20 node cluster, 8 processors per node. Each node has a name, e.g., "vm0000", "vm0001", etc. Within a foreach loop, I would like R to tell me what node it is actually running on. How can this be accomplished? Thanks! require(doMPI) cl <- startMPIcluster(16) registerDoMPI(cl) x <- foreach(i = 1:16) %dopar% { <some

I'd like to announce the availability of the new "doMPI" package, a parallel backend for the "foreach" package, which acts as an adaptor to the "Rmpi" package. The package has been uploaded to CRAN and is now available. Like the "doSNOW" package, "doMPI" allows you to execute foreach loops in parallel using "Rmpi" as the underlying

Hello, I'd like to add a wiki page for the HP Pavillion DV7-2250ED laptop. The proposed position would be http://wiki.centos.org/HowTos/Laptops/HP/Pavilion-DV7-2250ed I'd like to add the steps needed to install, and what's needed to get wireless working (and anything else that pops up after that).

I'm attempting to run a rather complex routine that involves a few loops, and even some use of foreach and doMPI. I just added another external loop and now get this error message. Error in { : task 3 failed - "NA/NaN argument" Is there a way to debug what is causing this error or where? I really have no idea what "task 3" is? Thanks Jim

Hello My name is Marcin, I am pleased to write here ; -) a have some problems with syslinux. I hope that you will help. On my company we use the syslinux from a long time. Now we use the sys(pxe)linux 4.06 and working very well. Yesterday i starting collect the needed files for syslinux 6.02 BIOS on virtualbox 4.3. I test everything, memtest, Windows PE, ubuntu etc.. everything works well. I

Question 1: I have a long list of variable names such as first <- c("one","two","three") and what I want to do is create a list of lists ... where the names of each of overall lists components are "one","two", and "three". This is the same result as second <- list(one=list(),two=list(),three=list()) Is there a way to exploit

i think there ara two ways of relate products and categories , basically i want to fix one product(e.g hp dv7....) to some categories (notebook,17"notebooks...) i made a table named categorization(incuding category_id,product_id fields) then in models i write these codes below class Product < ActiveRecord::Base has_many :categories, :through => :categorizations

Hi there. I had a quick look through the archives, and I spotted a similar issue being reported in October, but no resolution, unfortunately.

CPU: Intel i7, BIOS: InsydeH2O version: F. 12 With syslinux 4.06, it boots flawlessly. With syslinux 6.01 and 6.02, the

Hi Thanks for confirmation about syslinux 6.02 requirements. I see small misunderstanding. A used word "Syslinux 6.02 BIOS" mean the respective syslinux binary files from "/bios" subdirectory for PC's with Legacy PXE or PC's with PXE where CSM mode is enabled. Some idea where is the issue? Do the syslinux 6.02 working well from PXE on multiple PC's in your place?

Thank you very much Steve. Your suggestion works perfectly -- at least with doSEQ, doMC and doMPI.

I?m trying to achieve small scale parallelism, where tasks take 1-5 seconds and make fuller use of consumer hardware. Its not a HPC-worthy computation but even laptops these days come with 4 cores and I don?t see a reason to not make

It frequently runs out of memory, even when there is plenty of available memory on the system and even plenty of free process virtual address space. This tends to happen far more often when allocation a number of large objects
