Re: [Axiom-developer] How to allocate more space for Axiom on Windows

[William Sit]

Thanks, Waldek. I tried as you suggested; the allocate produces a system
error unless I use a very small number. Nonetheless, the CONS type space
seems to have 200000 even though there is an error message.

However, when I run the computation, it stops again. So I am not sure if
I got any extra space that way (the max page is still the same) or it is
some other type of memory that needs to be increased.  I am limited to
131072 pages (using (room), as suggested by Gregory Vanuxem -- Greg,
thanks for the docs). So it looks like 512MB. I am using a precompiled
version on Windows. I have no idea what gcl I am using.

I also tried the commands from SI but the run always quit after using up
the pages (but there is still plenty of physical memory).
