OS on the server

I made some benchmarking at my computer today.
The test was to see how much Marwin would gain if I started using the 64bit version of Ubuntu. From Marwin's perspective it would definetly be a big gain, on the positions that I tested he was 86%-112% faster (after a recompile) than the 32bit version. The 32bit version of Marwin was unaffected by the change of OS.
The question I have now is: Does the server run 32bit or 64bit versions of CentOS?

I run 32-bit Debian and I don't know how to cross-compile programs to 64-bit architecture. Though Badger would probably gain a lot too, as it uses full-board bitmaps all the time.

Clueless gets roughly the same speedup going from 32bit to 64 bit.
This year's tournament was run on a 32 bit OS. Hopefully next year's will be on a 64 bit OS.

The nice thing is that you don't have to. Because all programs that is compiled as 32-bit programs will run just as good in a 64-bit OS, at least that's what I've heard and it worked for Marwin.
But the programs that get compiled for the 64-bit arch will gain by being able to use the hardware to the fullest, at least bit-board-bots. And you could recompile the bot at the server if Omar has the compiler for your language.
