You can still run 32bit software under a 64bit system, LeSC is already
using a 64bit system. The only problem is that python/perl/etc. are
64bit so if your software provides 32bit libraries that are loaded
from the interpreters it will fail. The solution is to provide 32bit
versions of python/perl/etc. and put them in front of the path for
the lcg queues (I guess that you can even start the job with setarch
i686 so that even uname -a will tell you are running in 32bit).
That of course will stop 64bit software that wants to use the interpreters
with their own libraries but thats uncommon for now but you can always
get extra queues that use the system ones. Users will have to choose
the right queue but it is better than not supporting everything.
I am sure David can provide more details about the LeSC setup which
is already running this way.
Cheers,
Kostas
