For scheduling purposes, it fires every 10 milliseconds. As in Linux, this is a clock "tick." Note that 2.6 Linux uses a 1000-tick/second clock, as opposed to the 100-tick/second clock used by Solaris and by previous versions of Linux. User-level programs on Solaris can program the real time clock to fire at nanosecond granularity, rounded up by processor time-- much finer than the clock tick granularity of ten or one milliseconds. However, the program interface to use the high-resolution timers is not visible in the DDI/DKI. See clock_settime(3rt) for user-level details andusr/src/uts/common/os/cyclic.c for details on high-resolution timing in Solaris. Also note that in Solaris, you can change the value of hz or clock ticks/second by setting hires_tick to 1 and hires_hz to the desired time in the /etc/system file. The default is 1000 ticks per second. Here's an example: set hires_tick=1 set hires_hz=10000 <~--- 10000 ticks per second" Looks like Solaris can set it in user mode, too. This 'documented' tick rate would seem to meet simh's requirements without any adjustments. Does the current simh code work? If not, what does it think the tick size is? I will tell you once I work around ld: fatal: auxiliary filter option (-f, --auxiliary) is only available when building a shared object ld: fatal: flags processing errors ;) Are you getting this problem while building the simh vax? You are just typing: $ make vax Right? Yup. Please supply the output make produces while building. bash-3.2$ gmake vax lib paths are: /lib /usr/lib using libm: /lib/libm.so using librt: /lib/librt.so using libpthread: /lib/libpthread.so /usr/include/pthread.h using libdl: /lib/libdl.so /usr/include/dlfcn.h using libpcap: /usr/local/lib/libpcap.a /usr/local/include/pcap.h *** Warning *** *** Warning *** vax Simulator being built with networking support using *** Warning *** libpcap components from www.tcpdump.org. *** Warning *** Some users have had problems using the www.tcpdump.org libpcap *** Warning *** components for simh networking.

Then it builds fine. ;) - Mark
