Hi Pavel,

We use:
- RHEL 6.1, physical & virtual, and RHEL MRG-R 2.0 both with x86-64. 
- EPICS 3.14.12.2.
- Control System Studio (CSS) 3.1.
It works fine.

We prefer configuring controllers without CSS to avoid users starting BOY/BEAST on controllers (for resources reasons) but we also use RHEL for servers and operator stations.

Cheers,
Franck

Pavel,
The popular OS for soft IOC is Linux-x86 and x86_64, WinXP_32 (can't comment on Win7, or 32/64 bit support).  For real-time: vxWorks, RTEMS, and a few years back there was a RHEL-based RedHawk Linux.  We use RHEL here for corporate reasons, but CentOS is supposed to be the same (only better/more current).

I'd be interested to hear what others say about CSS being better under Windows; I know it runs on Linux, and I vastly prefer to avoid Windows for controls applications.  Does CSS run on MacOS?

The IOC doesn't have a GUI, only a command line terminal.  The GUI (e.g. CSS) runs on a client machine.  Depending on your IOC's application, it should be OK to run the client (CSS) and server (IOC) on the same physical box.  Although, I have never done that.

-ps
