We are running mixed userspace 64/32bit (all kernels 64bit) linux 1.0.10  
cluster for our daily operations for months now without issue.

can I have a mix of 32 and 64 bit machines in a cluster?

I can't imagine why this would be a problem but I wonder if anyone has
experience with running a mix of 32 and 64 bit nodes in a cluster.

(I'm not going to do this in production, just trying to make use of the
gear I have for my local system).

Thanks.

Java abstracts you from all these problems. One thing to look out for
is JVM options do not work across all JVMs. For example if you try to
enable

32bit machine the JVM fails to start.
