| Rev | Line | |
|---|
| [9083] | 1 | .SH "DG/UX 5.4 DIFFERENCES" |
|---|
| 2 | The WCPU and SIZE columns are not shown, nor is the "last pid" display, as |
|---|
| 3 | this information is not available from the kernel. |
|---|
| 4 | A "processor utilization" column is added, with the heading C. This number |
|---|
| 5 | reflects a process' relative interactivity, represented by an integer from |
|---|
| 6 | 0 to 7. A process with 7 is highly interactive. A process with 0 is not |
|---|
| 7 | considered interactive, but uses mostly CPU resources. |
|---|
| 8 | The "nice" processor time is not shown, but a "io_wait" processor state is |
|---|
| 9 | added, represented the time spent waiting on I/O operations. This is |
|---|
| 10 | currently always set to zero. |
|---|
| 11 | |
|---|
| 12 | Process are considered "idle" unless they are in "run" or "wait" state. |
|---|
| 13 | Process are considered to be "system" processes if they have uid=0 and |
|---|
| 14 | ppid=1. |
|---|
| 15 | Percent CPU is not maintained by the kernel, and has to be calculated by |
|---|
| 16 | top, by dividing the difference in system+user time by the delay period. |
|---|
| 17 | |
|---|
| 18 | The DG/UX 5.4 port was written by Mike Williams <mike@inform.co.nz>. |
