Subject: [Rd] Running R on dual/quad Opteron machines
Message-ID: <3c12769c0603060850pd3bbc73gb40a5e9f324d8050@mail.gmail.com>

Dear all,

I am managing a departmental purchase of an Opteron based
workstation/server for scientific computing on which we will be
running R.
The environment will probably be either Unix/Linux or Solaris and the
amount of RAM will be 8-16Gb, depending on the number of processors.
My main concerns are the following:

1. How much does R  benefit from passing from one processor to
two/four processor machines? Consider that the typical intensive use
of the server
 will be represented by simulation studies with many repeated loops.
2. How does R cope with parallelization and/or parallelized compiled code ?

I would be very grateful if someone could give suggestions and/or
point me to information on the above mentioned issues.

Regards,

Simone Giannerini
