Full_Name: Emmanuel Charpentier Version: 1.6.1 OS: Linux 2.4.20 / Debian Woody Submission from: (NULL) (80.15.78.96) rsprng depends on libraries available in the "genesis" package. However, even when Genesis is installed, the installation of the source package fails for not finding rsprng.h. It turns out that Debian installs it in a subdirectoru of /usr/include, and that the rsprng packages assumes that it is...

Suppose I want to use *snow*, according to some reference, I need to use *rsprng* as a generator. Does this generator relay on seed as well? But it seems to me that if I do not use rsprng, it is also fine. ## code without rsprng ## testfun <- function(){ a <- rnorm(5,0,1) return(a) } library(snow) cl <- makeCluster(5,type="SOCK") clusterCall(cl,...

When I try to install Rmpi, it has a dependency rsprng which, as its description says: Provides interface to SPRNG 2.0 APIs I installed it on Mepis by installing the appropriate debs with minimal drama. In the rpm world of Fedora, no such luxury. Installing rsprng fails because: checking sprng.h usability... no checking sprng.h presence... no che...

Dear R-users, Does anyone of you have binary files for the packages rpart.permutation, snow and rsprng. I would like to use them in my classification tree. I know they are still at the 0.x development stage, though. Where can I get information on how to compile tar.gz files? I'm using windows XP with R 2.1.0. Thanks, Jan -------------------------------------------------------------------- Jan...

...hat is, I want each distributed process to recreate exactly the same random numbers that it did before; I assume SPRNG assures the streams are independent betweeen processes. Here's what I did, trying to stick within SNOW to avoid trouble (from memory): lamboot start up R library(snow) library(rsprng) library(rmpi) cl<-makeMPIcluster(11) clusterSetupSPRNG(cl, seed=123) clusterEvalQ(cl, source("mycode.R")) r<-parSapply(cl, seq(1000), function(i) doMyThing())) Any comments on that? For example, would sticking to Rmpi and using parSim make sense (I'm not using seq(1000) for a...

...number of 32 bit integers. The code for PutRNGstate(), for example, uses them in just that way. While the dominant model, even on 64 bit hardware, is probably to leave int as 32 bit, it doesn't seem wise to assume that is always the case. I got into this because I'm trying to extend the rsprng code; sprng returns its state as a vector of bytes. Converting these to a vector of integers depends on the integer length, hence my interest in the exact definiton of integer. I'm interested in lifetime because I believe those bytes are associated with the stream and become invalid when the...

Although this query was inspired by distributed random number generation, one of the questions (#2 below) is a single-machine issue. I call C++ code from R to generate simulated data. I'm doing this on a cluster, and use rmpi and rsprng. While rsprng randomizes R-level random numbers (e.g., from runif), it has no effect on the C code, which is completely SPRNG and MPI ignorant. Currently I generate a seed to pass into the C code, using as.integer(runif(1, max=.Machine$integer.max)-.Machine$integer.max/2) It seems to work. Any c...

Hello All, I'm trying to install rattle from source on a AMD64 machine running etch. I have two packages installed from the etch backport (r-cran-rodbc and r-cran-rsprng) but all the rest installed from source. I'm trying to install rattle, but install.packages("rattle", dependencies=TRUE) Tries to install rggobi, which complains about the version of libggobi. Does this mean that there isn't a way I can install rattle on etch? * Installing...

From reading on http://sprng.cs.fsu.edu/ 'rsprng' provides just opposite of what I want, 'rlecuyer' is a bit to technical for me, but I think it also doesn't give identical seed for parallels.

...the period really related to 2^32, or is it dependent the architecture, 2^64 for 64 bit R and 2^32 for 32 bit R? I noticed there are several packages related to RNG- please direct me to a vignette/R news article/previous post if this has been covered ad nauseum. I have skimmed vignettes/docs for rsprng package, RNG doc in base, setRNG package, mvtnorm package vignette (Or am I setting myself up to write a current RNG doc?) (directed to Gregory Warnes) I found a presentation by Gregory Warnes from 1999 addressing these same questions (and uses a "collings generator" in some C code). h...

...m working using Rmpi with the model of 1 R master and n C slaves. What I am trying to do is have each of the C slaves generate a random number from U[0,1], and then have the master collect all n numbers as a vector and output it. However even doing this is rather over my head. I'm trying to use rsprng and sprng, but I am sure what I am currently doing is wrong. I enclose a first attempt. Any suggestions would be appreciated. Thanks in advance. Faheem. ************************************************************************* ran...

...ed the function so that replicate is used to call the clusterCall function (ie. replicate(2, clusterCall(cl, runif,2),simplify=F) ) and resolved the random number issue. However, this also involves much more communication between master and slaves and results in slower computation time. Will rsprng fix this problem? Is there a better way to do this without using replicate? I hope this is somewhat clear. Thanks, Mike
