Compaq versions

On the Compaq Alphaserver DS20, and probably on most other Compaq machines, you must ensure that the maximum stack size is sufficient to run ADF1999. As a user you can use a command like:

to adjust the maximum stacksize. The here displayed value is reasonable. A default of 2048 would be too small.

Note that you should do this before starting ADF and also before starting the PVM daemon. Preferable is, of course, to set this in your login-shell or, even better, system-wide.

ADF will crash with memory errors if the stack size limit is too small.
