Hello, 1. Thank you Mark for the new master version. It builds perfect now:
virtual:~/SIMH/build-master/markpizz-simh-a280dd2 # make BIN/vax if test ! -e BIN; then mkdir BIN; fi gcc -std=c99 -U__STRICT_ANSI__ -g -I . -DUSE_NETWORK -DUSE_TAP_NETWORK -D_GNU_SOURCE -DSIM_ASYNCH_IO -DUSE_READER_THREAD VAX/vax_cpu.c VAX/vax_cpu1.c VAX/vax_fpa.c VAX/vax_io.c VAX/vax_cis.c VAX/vax_octa.c VAX/vax_cmode.c VAX/vax_mmu.c VAX/vax_stddev.c VAX/vax_sysdev.c VAX/vax_sys.c VAX/vax_syscm.c VAX/vax_syslist.c PDP11/pdp11_rl.c PDP11/pdp11_rq.c PDP11/pdp11_ts.c PDP11/pdp11_dz.c PDP11/pdp11_lp.c PDP11/pdp11_tq.c PDP11/pdp11_xq.c PDP11/pdp11_ry.c PDP11/pdp11_vh.c PDP11/pdp11_cr.c PDP11/pdp11_io_lib.c scp.c sim_console.c sim_fio.c sim_timer.c sim_sock.c sim_tmxr.c sim_ether.c sim_tape.c sim_disk.c -DVM_VAX -DUSE_INT64 -DUSE_ADDR64 -I VAX -I PDP11 -o BIN/vax -lrt -lpthread -lpcap I have added to vax.ini on Ultrix set cpu idle=ULTRIX and on VMS set cpu idle=VMS and here is the result on ULTRIX V4.5 (Rev. 47) # uname -a ULTRIX ultrix 4.5 0 VAX sim> sh cpu CPU, idle=ULTRIX, idle enabled, stability wait = 20s, minimum sleep resolution = 2ms, 256MB, HALT to console ...and VMS $ sh sys /noproc OpenVMS V7.3 on node VAX 20-SEP-2011 06:33:43.99 Uptime 0 01:02:01 sim> show cpu CPU, idle=VMS, idle enabled, stability wait = 20s, minimum sleep resolution = 2ms, 256MB, HALT to console ...and indeed it works perfect for the VMS client PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 4815 root 30 10 323m 77m 5232 S 11 1.0 2:34.99 /root/SIMH/vms/bin/vax but not for Ultrix.

That did not help either on Ultrix client, while the VMS client was nicely running consuming just about 10-15 % of the CPU. Mark, can I help you somehow to solve this idle issue with Ultrix client? 2. >The boot setting are stored in the simulated NVRAM. Simh only updates >this file when you exit Simh.

Now it boots as it should :) Thank you very much for all help.

I have > tested the "set cpu idle" command but the CPU is still in 100% usage The, as yet unreleased, code which you are now using has a different (I believe more robust) idle implementation for the VAX simulator. I believe that the current code will work correctly on most host systems given a host clock tick which is less than 10ms. The real issue is the minimum resolution on sleeping (1ms is good, 10ms isn't so good). The current code has a more robust means of determining the minimum sleep resolution. What version of Ultrix are you using? You should be using: sim> set cpu idle=Ultrix I just updated the code to display the minimum sleep resolution when you enter the command: sim> show cpu idle Please try the latest version to display the minimum sleep interval and let me know your Ultrix version.
