[Emc-developers] exploring the LinuxCNC 'burden' on my BeagleBone Black

2013-06-06 Thread Kent A. Reed
Gentle persons:

My interest has been tweaked by several remarks made about performance 
on the BeagleBone Black. I've started a page 
(https://sites.google.com/site/manisbutareed/beaglebone-black-linuxcnc) 
and to kick it off posted some gross characterizations of the burden 
imposed by various LinuxCNC GUIs and use of SSH/X11 Forwarding.

This has been a little something to keep me busy in the wee hours

It's interesting that ssh for the X forwarding is a big chunk of your 
CPU utilization.  Have you tried switching ssh form the default 3des 
cipher to blowfish?  It's much faster.

[Emc-developers] Rockhopper revisited

2013-06-06 Thread Gene Heskett
Greetings Guys;

Someone mentioned that rockhopper can make .pdf
s somehow, and those of coarse can be scaled.

Since I now own an HL3170CDW color laser printer, what steps does it take 
to do this, blowing my lathe .hal file up into at least a 6 page output?

Progress on the lathe, it seems I bought a dud controller on ebay, blown in 
a manner similar to what I did with the first one.  So rather than pour 
more money down that rat hole, I've ordered one that uses HEXFET's, good 
for 25 amps, runs dead silent.  Nominally $150, some outfit in Wisconsin 
makes it.  And I've located the rest of the chips to shotgun the C41, so 
maybe I'll be turning the spindle motor again by Monday evening.

Thanks for any help on rockhopper.

Cheers, Gene

very interesting writeup! very much in line with my observations

I have so far run with a remote X display directly  (i.e. without ssh 
tunneling) by setting DISPLAY on the bb and enabling connect on the X server, 
so no sshd overhead but more involved startup

also interesting to note - the core parts (milltask and the interpreter 
embedded therein, plus rtapi_app and usercomps) use negligable CPU compared to 
GUIs

Re: [Emc-developers] exploring the LinuxCNC 'burden' on my BeagleBone Black

2013-06-06 Thread David Bagby
Hi Kent,
I was your dev list post and noticed that your blog link says that 
you're running the starter kit from Michael on a BBB and that it's a 3.8 
kernel with Xenomai etc.  I  was about to build a 3.8 for the BBB etc, 
but decided to ask Michael where to find whatever he's already built.
He responded that there would not be a 3.8 for a couple of weeks - so 
I'm confused.

Can you point me to the source of the software load referenced in your blog?
Dave

Opps! Shot from the hip without reading the nice summary Kent put

There's more to come in the details that I haven't posted yet. Despite 
blowfish and arcfour both being faster---it must be true, I read it on 
the Internet---they don't substantially aid here. The issue may be 
clouded by the ARM chip which I suspect isn't tweaked the way many x86 
chips are, and the algorithms in the OpenSSH routines, which I suspect 
may have been tweaked for x86. There were differences to be sure, just 
no home runs.

  The ciphers I forced my SSH client to select using the -c option were

 -c (default) aes128-ctr
 -c arcfour256
 -c arcfour128
 -c arcfour
 -c blowfish-cbc

I also ran throughput tests between the hosts, using 'dd' to generate 
very large files of zeros in memory (to avoid benchmarking the file 
system) on the BBB and piping them through ssh to one of the x86 hosts. 
Haven't had time to post the numbers.

I did not see any significant advantage to using compression (-C 
option), either. That's a technique often used in WAN communcations, 
whereas my hosts are communicating over a single LAN segment.

Regards,
Kent

Gene,

fwiw

try pdfposter or posterazor or poster or scribus
all available from synaptic
i may have lots of repositories enabled
but one of those oughtta be availble to you
all of the print huge posters on std letter paper ready to be taped together
i dont print stuff anymore , but when i worked on big hal diagrams
i used similar tools and taped the sheets together

yes, a big problem with such diagrams is size and scale
when its small enough to overview you cant see the problem point
when you can see the problem point you cant see the overview
:|

maybe some of the newer 'lensing' code may help ( fisheye zooms a bit, 
leaving the overall view as well )

btw svg is zoomable/panable so maybe you could use a good svg viewer 
rather than a pc of paper. up to you.

also organizing hal work in 'sheets', hierarchically, like old orcad, helps

regards
tomp

2013-06-06 Thread Gene Heskett
On Thursday 06 June 2013 18:55:24 EBo did opine:

 rockhopper?
 
Yeah EBo, it draws logic diagrams of what you have wired up in your .hal 
files.  But my lathe has so much stuff, that by the time I load its 
generated output into inkscape, and zoom in to where I can actually read 
the box titles, is about 2 feet high  pushing 6 feet wide, so if I want to 
print it, I need to run it thru a poster maker, tiling the image onto about 
15 sheets in landscape mode.

With that, I hope to see what I may have thats dead ended and can be 
removed, easing lcnc's workload in the servo-thread.

 Hi Kent, I was your dev list post and noticed that your blog link
 says that you're running the starter kit from Michael on a BBB and
 that it's a 3.8 kernel with Xenomai etc.  I  was about to build a
 3.8 for the BBB etc, but decided to ask Michael where to find
 whatever he's already built. He responded that there would not be a
 3.8 for a couple of weeks - so I'm confused.
 
 Can you point me to the source of the software load referenced in
 your blog? Dave

Michael's Xenomai stuff is currently living here:

http://static.mah.priv.at/public/beaglebone/starterkit/

The README has details on 'installation' (basically dd the raw image
to a 4G+ SD card, or extract the boot and root tar.gz files into
appropriate partitions).

I'm not sure exactly which version Kent used, but the latest and
greatest version (which is what I'm using):

Apply boot-new.tar.gz over the boot partition

Get the 3.8.13xenomai-bone20 kernel from the deploy/ directory and
install as follows:

extract 3.8.13xenomai-bone20-firmware.tar.gz in /lib/firmware
extract 3.8.13xenomai-bone20-modules.tar.gz in /
extract  3.8.13xenomai-bone20-dtbs.tar.gz in /boot/uboot/dtbs
the  3.8.13xenomai-bone20.zImage file goes to /boot/uboot/zImage

Michael is working on getting xenomai patched kernels into the
existing official kernel builds for the 'Bone, and I've been looking
at modifying RobertCNelson's image creation scripts to try and make a
LinuxCNC image that works similar to the Debian and Ubuntu SD images.

 very interesting writeup! very much in line with my observations

 I have so far run with a remote X display directly  (i.e. without ssh 
 tunneling) by setting DISPLAY on the bb and enabling connect on the X server, 
 so no sshd overhead but more involved startup

Because X11 Forwarding works so reliably, is so easy to set up, and is 
so the right thing to do for people who worry* about network security, 
I just use it automatically. This is my first situation where its 
performance became an issue.

For those who want to run in what I called naked X11 mode, there's a  
bit of magic needed if you are running your XServer on Ubuntu. Not only 
do you need to allow it to accept X connections, typically by invoking 
'xhost XClient hostname/IP' or 'xhost +' if you are lazy, but you also 
have to set it to allow connection via TCP. Ubuntu (well, actually 
Gnome) makes this unaccountably hard in its attempt to do everything for 
you. The traditional setting in /etc/X11/xinit/xserverrc is overruled by 
a setting in gdm.schemas.

You can prove this by changing xserverrc to allow TCP (eg., delete 
'-nolisten tcp' from the invocation) and restart gdm. Run 'ps ax' and 
note that X started with the 'nolisten tcp' option despite you just told 
it not to.

In Ubuntu 10.04LTS, at least, this tweak works:

In /etc/gdm/gdm.schemas, change 'true' to 'false' in the following stanza

 schema
   keysecurity/DisallowTCP/key
   signatureb/signature
   defaultfalse/default   --- here I've already changed 
'true' to 'false'
 /schema

Save and restart gdm using, for example, 'sudo service gdm restart'.


 also interesting to note - the core parts (milltask and the interpreter 
 embedded therein, plus rtapi_app and usercomps) use negligable CPU compared 
 to GUIs

For all my runs with the AXIS GUI, milltask was number two on the hit 
parade, consuming roughly 28 percent of CPU time and 3.1 percent of 
memory. With the other GUIs it was always less than 5 percent of CPU, 
more typically 2-3 percent, as were hal_manualtoolc and halui across the 
board. I looked at every task down to 'top' which always consumed about 
1 percent of CPU and 0.3 percent of memory. I was tired and only took 
the time in this first cut to report on the two that most concerned me. 
Details later, maybe.

Kent

* you can't work with computers at NIST for three decades and not be 
such. We wore belts and suspenders, so to speak. Public perception was a

Federal Information Processing Standards (FIPS). It just would not do

Internet blackhats don't try. Our firewalls were/are under constant

engineering practices. Sometimes dumb luck carries the day. We were one 
of the few major sites to sidestep the infamous Morris worm back in 1988 
but only because our principal mail server was running on VAX/VMS and 
not Unix. Sometimes not everyone gets the memo. Sometime in the 90s, we 
got hit right between the eyes by a vulnerability in Sun Solaris because 
we had Suns running on an experimental ATM (asynchronous transfer mode, 
not a cash machine) network connecting us by optical fiber to several 
universities. The ATM network bypassed the firewall. The Suns involved 
were all supposed to be in a DMZ, but dualhoming with the regular 
network was not unheard of. Naturally, security audits got more 
draconian. Designing, building, and maintaining an electronic condom is 
tough business.

 Gene,
 
 fwiw
 
 try pdfposter or posterazor or poster or scribus

Reading the descriptions, I installed scribus. It can blow it up ok, but 
when I asked for a printout, what would fit n one page at the size I had 
zoomed was all the printer gave me.  Next, I'll see if poster can deal with 
an svg file for input.  I did hit the posterazor site, but it mentions a 
trial period and never did tell me how much.  And pdfposter would need the 
thing made into a pdf to start with.

Possibly something can be worked out.  I was hoping there was a plugin for 
scibus, but if there is, its not in the buntu repo.


 all available from synaptic
 i may have lots of repositories enabled
 but one of those oughtta be availble to you
 all of the print huge posters on std letter paper ready to be taped
 together i dont print stuff anymore , but when i worked on big hal
 diagrams i used similar tools and taped the sheets together
 
 yes, a big problem with such diagrams is size and scale
 when its small enough to overview you cant see the problem point
 when you can see the problem point you cant see the overview
 
 
 maybe some of the newer 'lensing' code may help ( fisheye zooms a bit,
 leaving the overall view as well )
 
 btw svg is zoomable/panable so maybe you could use a good svg viewer
 rather than a pc of paper. up to you.
 
 also organizing hal work in 'sheets', hierarchically, like old orcad,
 helps
 
 regards
 tomp

It's deja vu all over again:-)

I just fired up Rockhopper again with the sim/axis/axis_mm config to remind
myself that it produces the halgraph image in SVG format. I saved the image
and looked inside. Right after the DOCTYPE declaration appears the
information line

Great. Graphviz graciously tells us what it thinks the image size should be
(SVG is scalable vector graphics and doesn't care). You'll have to figure
out the size of the printable area on your printer. Let's say its 8.25 X
10.75 (laugh if you must, you A4 bigots! It doesn't get any prettier
converting millimeters to points). At 72pt per inch, that's 594pt X 774pt
so the image size is roughly 3 sheets X 3 sheets.

You can use the ImageMagick suite (available through the Synaptic Package
Manager) to create a bunch of image files of the right size out of the
original SVG image:

convert -crop 594x774 halgraph.svg halgraph-%d.png

Hmmm. I get 12 images, not 9. Oh, wait, my roughly overlooked the fact
that the image is slightly wider than 3 sheets.

Anyway, there's your letter sheet-sized images. I tried to create the
images in pdf directly using convert but I got abnormally wide output
images. Similarly, I got strange results converting the png files to pdf
using convert. You could futz around some more to get good pdf conversion
or you can just print the png files directly from the Gnome Image Viewer or
whatever you're using.

As a matter of curiousity, what is the width and height information in your
halgraph.svg file? I suppose if it's big enough, convert could choke.

Kent
