Hi, I have some surprising trouble installing the gputools package. This is a linux box running Fedora with an Nvidia GeForce GTX 260 card and R 2.12.1 I had gputools running on it for the past several months. Wanting to update to the newest version, I simply executed install.packages("gputools") from within R. This should mean that the problem...

Hi, I'm trying to install a module - gputools - and keep getting compile time errors about missing R.h Does anyone know where this file can be found? Thanks!

I tried to use gpuCor function in the gputools package of R to calcuate the pairwise correlations of a matrix of 40,000 columns. Becuase there would be memory issues if I use the whole matrix at a time, I splitted the matrix into submatrix of 10,000 columns and then calculate the pairwise correlation of different submatrices. There are altoget...

Hi All, I have been reading about general purpose GPU (graphical processing units) computing for computational statistics. I know very little about this, but I read that GPUs currently cannot handle double-precision floating points and also that they are not necessarily IEEE compliant. However, I am not sure what the practical impact of this limitation is likely to be on computational

...elp, this post is not critical. it is more curiosity. Integration: for me, I want to substitute the basic statistical functions with GPU versions: mean, var, sd, lm, lm.summary, sort, order, quantile (, and maybe lapply with plain arithmetic functions). one of these functions is already in gputools (gLm). I did not see the others, but some functions (like mean) may well be used internally. is there an R GPU library that can swap-and-replace these eight functions "seamlessly and transparently"? Benchmarks: I wonder what the typical speedup for these functions are in mainstream sy...

...the user to run a function that detect the OS and presence of CUDA, and download the appropriate shared library file. The problem is as long as there are C code in src/, it will not pass CRAN check. Also, that seems to violate some CRAN policies. The other is simply to follow what packages like gputools/rpud/etc. and have only source package on CRAN, and provide Windows binaries off CRAN (perhaps with a note in the README on where to download them). We'd very much appreciate any pointer. Best, Andy Andy Liaw Biometrics Research, Merck Research Laboratories PO Box 2000 RY34-300 Rahway, NJ...

Hi all, If a package suggests another package in its description, you can check it at runtime with requires. How do you do check if a package is available without loading it, if you only want to access one function in the package namespace.

I've noticed that the implementation of Kendall's Tau in R is O(N^2). The following reference describes how it can be done in O(N log N): A Computer Method for Calculating Kendall's Tau with Ungrouped Data William R. Knight Journal of the American Statistical Association, Vol. 61, No. 314, Part 1 (Jun., 1966), pp. 436-439 http://www.jstor.org/pss/2282833 I'm interested in

Hello I am fortunate (or in really big trouble) in that the research group I work with will soon be receiving several high end dual quad core machines. We will use the Ubuntu OS on these. We intend to use this cluster for some extensive modeling applications. Our programming guru has demonstrated the ability to link much simpler machines to share CPUs and we purchased the new ones to take

Hi there, Moving this request for info over from an R-HPC-SIG list thread as the issue is less HPC than something that has bitten me as a result of trying to install HPC (read CUDA) R packages. Background to this is that I have both a Ubuntu host for a Tesla card that some researchers are looking to do CUDA-related R computation on, and a prototype, RHEL-based, cluster that is being used to

My question is based on a project I have partially done, but there is still something I'm not clear. My goal is to create a R package contains GPU functions (some are from Nividia cuda library, some are my self-defined CUDA functions) My design is quite different from current R's GPU package, I want to create a R object (external pointer) point to GPU address, and run my GPU function
