Dear all,
I wonder, if anybody experiences similar problems and if there are any simple
solutions to be suggested. We observe that R causes a lot of network traffic
and thus slows down the performance of the whole network. When tracing the
network traffic on the machine which serves the R installation via NFS, we see
thousands of requests at initialization of R processes and regular calls,
probably to shared libraries. Is there a way to compile or run R such that it
causes less load on the network?
Here is some information on our installation:
- We use a single installation of R (version 2.3.1) loaded over NFS
- there are approximately 1500 packages installed using ~8GB of disk
- We use R on a queuing system running up to 50 processes in parallel
The load on the machine which serves the R installation frequently rises up to
5 or so although it is a dedicated machine.
Any hints towards measures against network load are highly appreciated.
Thanks,
Claudio
