It looks like hugemem is a redhat thing... I don't know if it is
easy/possible to have it under debian. These kernels are generally heavily

But even with this patch, a signle process will be limited to less than 4G of
memory. As the hugemem kernels have switching overhead check if you really
can't work in another way.

Yes, you really need a 64-bit system for a single process to
efficiently use more than 1 (or is it 2?) GB or memory.

The consensus elsewhere seems to be that it's actually 3G per process, but that's still not enough for this application. Oh well....
