So I guess we are safe to run ATLAS 32 bit code on RHEL4 64 bit.

Hi Wei and Bob,
I got this confirmation that things should be OK on RHEL4 as long as the 32 bit compatibility libraries are installed.

PS Bob if you didn't ask me about RHEL4, then please ignore this email.

I see no reason why this shouldn't work. You ask specifically about 32-bit mode, and as long as they have the necessary RPMs to run the kit in this mode, I would have thought that development should have worked as well. There are know problems with 64-bit mode but development should work for that as well (or as badly) as it does at CERN.
