Thanks, Reid. Read that, but after having rebooted the computer and
with no program opened, I got the same problem. That is a fact that I
am using an old computer with not so much RAM.

Dumb question - does this program require a lot of memory? Could the system
run out of resources when you start the program so the system needs to kill
it off in order to have enough resources to keep running?

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...!
