similar to: Parallel code runs slower!

Hi all, I would like to parallelize some R code and would like to use the 'foreach' package with a foreach loop. However, whenever I call a function from an enabled package outside of MASS, I get an error message that a number of the functions aren't recognized (even though the functions should be defined). For example: library(foreach) library(doSMP) library(survival) # Create the

Dear R-List member, I have a problem when I'm trying to save two arrays from a foreach-loop. I'm also not sure whether this is possible or just my inexperience. However, this works perferctly fine with a for-loop. Here is an example code - any help is much appreciated!!: ############ n.vpn = 2 n.run= 3 # create to empty matrices sme = matrix(NA,4,n.vpn) test = matrix(NA,4,n.vpn) #

Hello LLVM people, Our customizable TTA target [1] is capable of having plenty of registers and register file ports to improve instruction level parallelism and reduce spills. It's totally up to the designer of the particular TTA processor how much the processor has registers and register file resources along with other TTA components. We have ported LLVM 2.1 to produce an intermediate TTA

Hello, Attached is a trivial patch to increase the max number of physical registers in LLVM from 1024 to 16384. In our TCE toolset we allow the designer to choose the number of registers in the designed TTA processors freely, and recently while experimenting with using TTA for a GPU design we have bumped into this limit several times. What has made matters a bit worse for us is that we need to

Hello, Can someone please commit this patch? Thanks.

Hi all, I think this master's thesis from our group could be of interest. It describes the "bridge" between the LLVM codegen and our custom TTA codegen in TCE: a runtime retargetable architecture description file driven LLVM compiler backend. The thesis might be useful also for people implementing backends for LLVM in general. http://tce.cs.tut.fi/doc/Compiler.pdf If you have any

Some might have noticed that REvolution Computing released the doSMP package to the general public about a month and a half ago, which allows multiple cores to be accessed for parallel computation in R. Some of our physical habitat calculations were taking an extraordinary amount of time to complete and required over-weekend runs, which prompted our interest in this package. What follows

Hi, Would it be possible to set tbgen to be installed with llvm? For our project http://llvm.org/ProjectsWithLLVM/#tta-tce it would be very helpful, because our tools generate compiler backend plugins in the fly for each customized processor and plugin generation needs tbgen for handling td files. Because of tbgen not beeing distributed, our users cannot use llvm from their favorite

Hi list, I was testing out the "doSMP" package from REvolutionR in my regular R2.11.0 installation and I got the following error message.? Well, one obvious thing is that R2.11.0 was built using "i386-pc-mingw32" which is different from what revoIPC used.? I could just use REvolutionR, but all my R peripherals were set up to work with the regular R2.11.0.? So, I really want

I am trying to get remote extensions to work correctly with agents. I have ackcall=yes and have agents logged in to extension 101 using agentcallbacklogin with extension 101 defined as: exten => 101,1,Dial(Zap/3/18165551234,20,tTA(custom/presspoundtoanswer)) This setup works great on local and/or voip channels, but on zap channels, the zap channel answers immediately as soon as it goes off

Hello, I'd like to use package 'doSMP'. But I can only found source codes in the CRAN. I tried to build source code using 'r CMD build doSMP' in the source directory, the following error is shown: ERROR: dependencies 'foreach', 'iterators', 'revoIPC' are not available for pack age 'doSMP' So, i tried to install dependency packages. But I

Hello dear list, I just noticed that: Package ‘doSMP’ was removed from the CRAN repository. http://cran.r-project.org/web/packages/doSMP/index.html Does any one know the reason for this? Is this a technical or a legal (e.g: license) issue?

Hi all I recently started to write a matrix exponentiation operator for R (by adding a new operator definition to names.c, and adding the following code to arrays.c). It is not finished yet, but I would like to solicit some comments, as there are a few areas of R's internals that I am still feeling my way around. Firstly: 1) Would there be interest in adding a new operator %^% that performs
