Hi,

When we try to run CMU Lisp on a Dec Alpha we get the following
message:

-- Unable to obtain requested swap space
mmap: Not enough space


We have 120mb swap and 64mb RAM installed. Does anybody have an idea
of how much more memory we might need? 

Thanks in advance,

Lael

rm /sbin/swapdefault

This changes memory allocation policy so that more memory than
availiable can be malloced/mmaped. CMU CL allocates more than it needs
on startup, about 260 MB. Only a fraction of those pages will actually
be used. So, if you cannot change you paging policy, you have to have
200 MB swap and 64 MB RAM for CMUCL plus whatever you need in
addition.
