Hello Everyone,

   We have recently purchased a server which has 64GB of memory running a 64bit OS and I have compiled R from source with the following config

./configure --prefix=/usr/local/R-2.9.1 --enable-Rshlib --enable-BLAS-shlib --enable-shared --with-readline --with-iconv --with-x --with-tcktk --with-aqua --with-libpng --with-jpeglib

and I would like to verify that I can use 55GB-60GB of the 64GB of memory within R. Does anyone know how this is possible? Will R be able to access that amount of memory from a single process? I am not an R user myself but I just wanted to test this before I turned the server over to the researchers..

Thanks!
