Greetings all; Sorta one of those days to hibernate, 3" of snow blowing all over, 19F etc in north central WV today.
So I'm sitting here with a couple ssh sessions going to that box, motor power off etc. I found that installing ksysguard give me a remote system monitoring facility, and am hoping its not lying to me. My base_thread is 20,000 now, which would I would think, show up as several percent of the 2nd cpu, the red line in the ksysguard system tabs display. When linuxcnc isn't running, I see, possibly at 10 second intervals, a barely visible spike to perhaps 0.5%, with isolcpus=1 in effect I've no clue what that might be. With linuxcnc running (without the taskset launch), and carving the logo, I see an occasional spike to perhaps 2% at about that same 10 second interval. And a spike to maybe 5% if I do something in axis like adjust the feed override slider. With a 20 microsecond base thread, and a 3 microsecond reset timing set in the .hal file, ISTM that core 2's usage should be higher that that. I do see in this utilities process list, an 'rtkit' that is caught using 2 or 3% very occasionally. And the hal_manual_tool_change shows up too. Keyboard response from here of course includes the network lags, but seems good enough that at a .28ipm jog rate, I can jog it half a thou with a quick tap on an arrow key. This, with a 30 microsecond base thread on the old machine, would not have been possible because it would run on for several seconds after the key was released. Whether I get the same results from its local keyboard remains to be seen and may be the result of running axis on a remote display & not burning cpu cycles for the local display since this boxes nvidia driven display is probably 20x faster than that machines intel based display is. >From this I get the impression that an additional box with good gfx might be a huge advantage even if the network cable was only 6 feet long. Discussion? Am I using the wrong tools to track this? In which case what tool should I be using?
