[R] computational capacity of Linux network

[Vadim Ogranovich]

Hi, This is not an R question per ce, but I feel like this is a right
community to ask it.

As a part of our work we run a lot of non-interactive computational jobs. To
increase the throughput we would like to distribute the load over the entire
network and we are looking at Linux network as a platform. Ideally we would
like to be able to submit a job to the network, rather than to a computer,
and let the "network" to figure out the resource to run the job on.

I'd like to hear from those people who have had an experience of working in
such an environment. Specifically
* what system (Red Hat, etc.) was used? What kind of software was used for
load balancing? 
* How big is the USER overhead to set such a job comparatively to running a
command from shell? How reliable and convenient error reporting is if the
job fails?
* how much of sysadmin time is required to maintain such a network?
* any other comment.

Please reply directly to me and I'll post the summary.

Thanks,
Vadim
