[Swift-user] Do you have any resource for learning about SwiftR?

Be mindful that Beagle now has a new ALPS and scheduler. It looks like the new ALPS is behaving differently from the old one. For example, the -N flag -- one MPI per node -- seems to be broken and ignored by ALPS, while perl now seems to be capable of running multiple MPI jobs per node (before there was no way of making it do that or at least we never found one and neither did Cray).

I did not have time to test either because I work someplace else today, so this is just little more than hearsay, I might be able to do it tomorrow. I plan to try to make Rmpi work and then move on from there.

>>The SwiftR documentation is currently at:
>>  http://www.ci.uchicago.edu/wiki/bin/view/SWFT/SwiftR
>>which also provides a quick start guide at:
>>  http://www.ci.uchicago.edu/wiki/bin/view/SWFT/SwiftRQuickstart
>>Further examples and some performance measurements are at:
>>  http://people.cs.uchicago.edu/~tga/swiftR/
>>And more examples are available with ?SwiftR help once you load the package:
>>> source("http://people.cs.uchicago.edu/~tga/swiftR/getSwift.R")
>>I just built an R-2.13.1 release on Beagle with plain gcc, which I think *should* be runnable in parallel on worker nodes. (Not yet tested though).  This R should be capable of running SwiftR.  Im hoping that Tim cam verify this soon. We'll likely need an additional SwiftR server name and config for Beagle and other Cray systems.
>>We'll try to consolidate the SwiftR documentation in a user guide on the Swift in the future. Tim, can you do a quick check of the documentation to make sure its still correct and that it points to the latest SwiftR package?
