>sorry, there are more complete list of my questions:
>1) Where I can get Firefly 8 beta for local machine?

You need to contact me off the list for this.

>2) Is this option (i.e. ulimit -s 2048) suitable for Linux versions of Firefly v 7.1.G?

Yes it is. Actually it affects the way how OS kernel partitions
virtual memory memory. This option may not help if your Linux distro
uses pre-linked shared libraries. In the latter case, try to google
a bit to find a way to disable pre-linking.

>3) Will be it works on FF installed on MVS-100 supercomputer of RAS Supercomputer Centre (Moscow)?

I do not know details on this particular cluster.
As I have explained this option affects OS behavior, not Firefly directly.

>4) What kind of Linux is the most suitable for 48-cores AMD computer in your opinion? Now I have CentOS-6.2-x86_64 on this PC. May be, it should replace on some other kind of Linux?

There is no good answer as it strongly depends on personal preferences.
Of Linuxes, I'd not recommend to use Debian and Ubuntu and clones.
Personally, I prefer SuSE; however, CentOS isn't bad at all.  
What is the CPU model of your 48-core system? For some models,
you may need to update kernel to get the optimal performance with Firefly.
