Hi all,
	on running some largish problems with octave on a sun, I find it
crashes catastrophically with a virtual memory failure in 'new'.  Any
ideas on how to get around this? 

I thought at first that it was the lack of grabage collection because it
would happen after a sequence of about 20 or so 360x360 singular value
decompositions (SVD).  However, it happens immediately after just one
640x640 SVD (plus a heap of smaller though substantial subsiduary
computaion).  Unfortunately, I really need to do these 640x640 problems
and almost certainly need to solve ones twice as big again.  Any
suggestions? 

On a different matter, I would also like to solve some really big problems
using octave on an IBM SP2 MIMD supercomputer.  Has anyone got any advice
on porting octave? 
                                     Tony      :-{)}
