SGI IRIX

To find out how much swap space has been allocated and is currently being used, use the swap command:

% /sbin/swap -s
total: 1.55m allocated + 124.47m add'l reserved = 126.02m bytes 
used, 250.94m bytes available

To find out how much swap space is in use while you are running TotalView:

1. Start TotalView with a large executable:

       totalview executable

2. Press Ctrl-Z to suspend TotalView.
    
3. Use the following command to see how much swap space TotalView is using:

       /bin/ps -l

   For example, in this case the value in the SZ column is 584 pages. 

        F S   UID   PID  PPID  C  PRI NI  P     ...
    b0 T 14694 26236 26271  5   62 20  *  ...

   Use the following command to determine the number of bytes in a page:

       sysconf PAGESIZE

To add swap space, use the mkfile(1M) and swap(1M) commands. You must be root to use these commands. For more information, refer to the on-line manual pages for these commands.
