Hello, Now that both PC and Mac have 64-bit CPU capable of addressing several gigabytes of RAM, will bioconductor be able to take advantage of this new feature without a major revision? I remember having a trouble trying to process 100+ chips at once due to limitation in addressable memory, so I'm curious. Shinichiro Wachi

Hi Shinichiro Wachi, we've been running bioconductor on a 64 bit HP-UX machine for a while. And that is nice since it indeed gives you lots of RAM (in our case, up to 96 GB). The only issue is to get all the compilers and necessary libraries in 64 bit versions when you compile R and install bioconductor. There are -to my knowledge- no inherent limitations with R or bioconductor.

Since I always compile from source, I was able to take advantage of the larger memory address space once I figured out the proper compiler options and no code changes to R or Bioconductor.
