- .SH "SUNOS 4 DIFFERENCES"
- On multiprocessor machines, the amount of time the processors spend in
- a spin lock is displayed along with the other processor state
- percentages. The percentages shown for processor states are averages
- across all processors. A process in run state also has its current
- processor displayed in the STATE column, for example "run/2" indicates
- running on processor 2. There is an extra column in the process
- display indicating which processor each running process is assigned
- to. Information about physical memory is displayed on the memory
- status line, but information about virtual memory is not available.
-
- Due to incompatabilities in kernel data structures, a top executable
- compiled on a Sun 4 multiprocessor architecture machine (sun4m) will
- not run correctly on a uniprocessor architecture machine (sun4), and
- vice versa. You will have to compile and maintain separate executables
- for these architectures. Yeah, I don't like it either.
-
- Some processes may show up with a resident set size (RES column) larger
- than total virtual memory size (SIZE column). This seems odd at first,
- but is a consequence of shared libraries: shared memory is counted as
- resident but is not counted in total size.

- The SunOS 4 port was written by William LeFebvre.
