Some Fedora Core and RHEL-based Linux distributions use pre-linking.
As far as I remember SuSE does not use it while some versions of CentOS (which is based on RHEL source code) could use pre-linking.


>Three years ago I  used SuSE (10.1 or 10.2) too. However at some moment SuSE started to run unknown process. In some minutes after I killed him, it was again running and speed of calculation decreased in 2-3 times. Nobody could understand what for this process is started and what it does. Then I have quarrelled about Linux :-).

Most likely, it was started by the cron daemon. :)

>As for my CPU model I have on 48-core machine four 12-core AMD Opteron Processor 6180 SE 2.50 GHz and CentOS. This system is not so friendly to the user and I would prefer to replace it, if there is more suitable system. I cannot to install driver for CUDA in CentOS (strange problem…).
