Hello
I have a problem of swaping....
1- The configuration of the station
my station is a COMPAQ AlphaServer DS10 617 MHz Tru64 UNIX V5.1A
with 1 Go of RAM
the configuration of the swap is:
B# swapon -s
Swap partition /dev/disk/dsk0b:
Allocated space: 98304 pages (768MB)
In-use space: 1 pages ( 0%)
Free space: 98303 pages ( 99%)
Swap partition /dev/disk/dsk1a:
Allocated space: 256000 pages (1.95GB)
In-use space: 1 pages ( 0%)
Free space: 255999 pages ( 99%)
Total swap allocation:
Allocated space: 354304 pages (2.70GB)
In-use space: 2 pages ( 0%)
Available space: 354302 pages ( 99%)
the others configurations are:

2- my problem
when I excute a C program I can't allocate a size table greater then the memory
size...
# ./a.out
try to allocate memory of 1092.727051 Mo...
1030 1030 1030 ... allocation failure 3 in f3tensor()
My question is:
Why my station can't use memory swap (2.70GB) to excute this program?
It seams like only RAM can be use...
What is wrong in my configuration ?
Best Regards
Josiane
