.SH "SUNOS 4 DIFFERENCES"On multiprocessor machines, the amount of time the processors spend ina spin lock is displayed along with the other processor statepercentages. The percentages shown for processor states are averagesacross all processors. A process in run state also has its currentprocessor displayed in the STATE column, for example "run/2" indicatesrunning on processor 2. There is an extra column in the processdisplay indicating which processor each running process is assignedto. Information about physical memory is displayed on the memorystatus line, but information about virtual memory is not available.Due to incompatabilities in kernel data structures, a top executablecompiled on a Sun 4 multiprocessor architecture machine (sun4m) willnot run correctly on a uniprocessor architecture machine (sun4), andvice versa. You will have to compile and maintain separate executablesfor these architectures. Yeah, I don't like it either.Some processes may show up with a resident set size (RES column) largerthan total virtual memory size (SIZE column). This seems odd at first,but is a consequence of shared libraries: shared memory is counted asresident but is not counted in total size.The SunOS 4 port was written by William LeFebvre.
