I was kind of curious about that myself, so I re-ran it with no spec
file.  Here's its ps output:

  PID USER     PRI  NI  VIRT   RES   SHR S CPU% MEM%   TIME+  Command
  9704 reid      20   0 1724M   892   704 S  0.0  0.0  0:00.00 ./algencan

That 1724M looks a little scary.  (I have 4 GB here.)

I don't speak fortran too well, but the code does seem to allocate
some decently hefty amounts of memory, such as this:

      double precision nl(nmax),c(mmax),rho(mmax)

where mmax is 500000.  There must be others, too.  Maybe you don't
want to run this thing on your low memory machine...!
