- I've recently acquired a VAXstation with 80 Mbytes of physical memory,
- and I would like to use the memory almost exclusively to run really
- big (large arrays) scientific computational code. I'm more than willing
- to sacrifice other management concerns.
-
- Unfortunately, my limited knowledge of VMS os management has prevented me from
- taking full advatage of the memory; whenever I run large executables the CPU
- spends about half its time in kernel mode, and the system also page faults an
- extraordinary amount considering there appears to be plenty of free memory as
- indicated by $show mem. I'd like my code to use all the memory available
- without resorting to faulting.
-
- Currently I've set:
- MIN_WSMAX=119531
- MIN_WSINC=1000
- and boosted up my user authorizations to:
- WSdef: 150
- WSquo: 163840
- WSextent: 163840
- Pgflquo: 163840
-
- Any advice would be greatly appreciated.
