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

[William Sit]

I was trying to solve a homogeneous parametric linear system
(9 by 9) with 18 parameters that Dhagash Mehta
<address@hidden> recently sent me. The
coefficient matrix is:

(1) -> )library PLEQN
   ParametricLinearEquations is now explicitly exposed in
frame initial
   ParametricLinearEquations will be automatically loaded
when needed
(2) -> amat := [[-a[1, 2, 1, 1] - a[2, 1, 1, 1] - b[1, 1, 1,
3] - b[1, 1, 3, 1],
 a[1, 2, 1, 1], -b[1, 1, 1, 3], a[2, 1, 1, 1], 0, 0, -b[1,
1, 3, 1], 0, 0],_
  [a[1, 2, 1, 1], -a[1, 2, 1, 1] - a[1, 3, 1, 2] - a[2, 2,
1, 2] - b[1, 2, 3,2],
 a[1, 3, 1, 2], 0, a[2, 2, 1, 2], 0, 0, -b[1, 2, 3, 2], 0],_

  [-b[1, 1, 1, 3], a[1, 3, 1, 2], -a[1, 3, 1, 2] - a[2, 3,
1, 3] - b[1, 1, 1, 3]
- b[1, 3, 3, 3], 0, 0, a[2, 3, 1, 3], 0, 0, -b[1, 3, 3,
3]],_
  [a[2, 1, 1, 1], 0, 0, -a[2, 1, 1, 1] - a[2, 2, 2, 1] -
a[3, 1, 2, 1] - b[2, 1,
2, 3], a[2, 2, 2, 1], -b[2, 1, 2, 3], a[3, 1, 2, 1], 0, 0],_

  [0, a[2, 2, 1, 2], 0, a[2, 2, 2, 1], -a[2, 2, 1, 2] - a[2,
2, 2, 1] - a[2, 3,2
, 2] - a[3, 2, 2, 2], a[2, 3, 2, 2], 0, a[3, 2, 2, 2], 0],_
  [0, 0, a[2, 3, 1, 3], -b[2, 1, 2, 3], a[2, 3, 2, 2], -a[2,
3, 1, 3] - a[2, 3,2
, 2] - a[3, 3, 2, 3] - b[2, 1, 2, 3], 0, 0, a[3, 3, 2, 3]],_

  [-b[1, 1, 3, 1], 0, 0, a[3, 1, 2, 1], 0, 0, -a[3, 1, 2, 1]
- a[3, 2, 3, 1] -b[
1, 1, 3, 1] - b[3, 1, 3, 3], a[3, 2, 3, 1], -b[3, 1, 3,
3]],_
  [0, -b[1, 2, 3, 2], 0, 0, a[3, 2, 2, 2], 0, a[3, 2, 3, 1],
-a[3, 2, 2, 2] -a[3
, 2, 3, 1] - a[3, 3, 3, 2] - b[1, 2, 3, 2], a[3, 3, 3, 2]],_

  [0, 0, -b[1, 3, 3, 3], 0, 0, a[3, 3, 2, 3], -b[3, 1, 3,
3], a[3, 3, 3, 2],-a[3
, 3, 2, 3] - a[3, 3, 3, 2] - b[1, 3, 3, 3] - b[3, 1, 3,
3]]];

(2) -> psolve(amat)

   >> System error:
   The storage for CONS is exhausted.
Currently, 82689 pages are allocated.
Use ALLOCATE to expand the space.

Can any one tell me how to increase the space? Exactly how
big is one page? I have 2GB RAM. Is it possible to allocate
the max to Axiom (under Windows XP)?

Thanks.

William
