This is strange. Boinc is running on my Linux machine. I just happened to me watching when it suspended a PAH WU and started a new EAH WU. When it did, A small window appeared with the EAH graphics. Some kind of spinning star map. I dismissed the window and EAH produced the following:

2005-02-09 18:16:18 [Einstein@Home] Result H1_0267.9__0268.0_0.1_T09_Test02_3 exited with zero status but no 'finished' file
2005-02-09 18:16:18 [Einstein@Home] If this happens repeatedly you may need to reset the project.
2005-02-09 18:16:18 [Einstein@Home] Restarting result H1_0267.9__0268.0_0.1_T09_Test02_3 using einstein version 4.76


When the WU restarted the graphics window did not come back. I stopped and restart the core client and the graphics window also did not come back.

Remember, this is on my Linux box, not a Windows box where I believe the graphics is pretty standard.

Anyone know what's going on? Can I get the graphics back (not that I want it, since it wastes cpu cycles better left for crunching, but it would be interesting.) Anyone got a pointer to what the graphics represent (if anything)?

I know nothing of Linux, but the "spinning Star" is actually the universe, and it is the Einstein graphic. Look down the threads and you'll learn more about it.

Go here to find out about the graphic.

Charles,

Both the Linux and Mac applications that we are distributing are 'graphics capable'. However most Linux & Mac users don't see the graphics because the BOINC project has not yet done a public distribution of the BOINC manager, which is the tool that sends the 'display graphics' and 'undisplay graphics' commands to the application. We have been using and testing this tool on Linux and Mac for several months. Hopefully the BOINC project will start public distribution of this tool soon. Then Linux and Mac users can watch the graphics too!

Cheers,
Bruce

Thanks for that info. But, I wonder what happened to cause the graphics to appear like that. I'm running Boinc 4.19 on my Linux box and there is no way I know of to make them appear.


Hmmm. Makes me wonder. I know how the rpc connection works so that an external application can talk to the core client. In fact, I use a PHP application written by, I think, the fellow who puts out BoincView. I can control and monitor my boinc installation from any web browser. I'll have to dig into the code for that and the core client to see if I can get it to display graphics, too. Something to do for the weekend!

Yup, it works! From a terminal window I connected to the RPC port using telnet. Then I sent it the command <result_show_graphics> and up popped the EAH graphics. It was running an EAH WU at the time. I quickly added this option to the PHP script I mentioned above. However, by the time I did that it had switched to a PAH WU and that does not have graphic capabilities. Have to wait until it switches back to the EAH WU.

You know it never occured to me that one could just telnet in -- it's a good idea. Could you please post a brief transcript of your telnet session? It sounds like a good debugging technique for some purposes.

OK, here's how it's done. Fire up a terminal window - xterm, konsole, whatever.
What port you use depends on the versions of the core client. 4.19 and earlier use port 31416. The 4.5x, 4.6x (and maybe the recent 4.20?) use a different port 1043. Since I have 4.19, I use port 31416. This is what it looks like:

telnet localhost 31416 --I entered this
Trying 127.0.0.1... --
Connected to localhost. -- System responded with this (3 lines)
Escape character is '^]'. --
<result_show_graphics> --I entered this.
<success> --System responded. Graphics appeared
^] --control right bracket to get telnet prompt
telnet> quit --enter quit to end telnet session
Connection closed.

That was it. You do neet the telnet service enabled on your linux box. Mine was not by default. My router keeps it blocked from the Internet.

Hope this helps.

Charlie

Thanks!

BTW, this also works on the Mac and even on Windows.

> You do neet the telnet service enabled on your linux box.

Why? The telnet client should work without having a server running on the machine. In this case the boinc client should be the server that is contacted by telnet. Is there a telnet client distributed with any Linux distri that doesn't work without a telnet server?

You're right. I should have realized that. I had enabled telnet a while ago so I could reach my Linux box from another windows box on my home network. Was having some problems at the time and X would hang. (Don't worry, my router does not allow telnet through so you can't get to me from the Internet.)_

While we're talking about the graphics on Linux, I just wanted to report a couple of things.

I read the page on this site describing the graphic and how to make changes to them. As described, I can use the mouse to zoom in and out and to rotate the celestial sphere. However, the other keyboard commands listed do not seem to work.

OK, way cute!

But they always want more:

- what's the command to turn OFF this graphics window (without shutting down E@h) ?

- Is there a way to turn off the automatic rotation ? (I'm getting sphere-sick watching it move!)

The keyboard commands are working in a test version of the code but are not yet in the production version of the code.

1. simply close the graphics window. Works for me.

2. Not that I know of.

Hi !

Maybe it will a good idear, that Users who have the graphics will test them and report any problems with the graphics.

Duds that is development here and we are here to test the new Apps and things from the project, so please test the new graphics for errors and make a report, without such tests the LINUX version will never have a graphic interface ! ;-)

Ok i also prefer the commandline Version, but ... you know ;-)

I have never seen any graphic on my LINUX box ! What a shame! :-(

I just got the graphics for OS X using the directions below. Very cool, definitely seems a lot more cpu intensive than SETI (at least the old version). Anyone able to tell me about CPU terminology? What I mean is in my activity monitor for cpu I see %user, %system, %nice and %idle. I can guess at idle and user, but what is nice? I see that is primarily what boinc is using.

____________

The graphics shouldn't be CPU intensive, as they are mainly done by the graphics card, not the CPU.

You can assign priority levels to processes so that some are executed when there's nothing else to do. These processes are "nice" in the sense that they step back when there is more urgent work to do. %nice is the amount of time the CPU spends with such processes.

Maybe intensive was the wrong word. My cpu monitor is pretty much topped out, but it is all blue (nice). It seems to have very little or no impact on system performance. I've had it going all day and haven't noticed any slowdown for normal activities. Einstein is processing pretty slow, but then I'm only on a 1GHz G4. If nothing else it sure makes it look like I'm doing something really important.

Sweet! Got it working on my Mac also. Pretty cool it shows up 2 seperate windows with different graphics since I have a dual CPU G5 :)

Speaking of... is it actually doing a seperate WU on each processor??? Or is it splitting the load of a single WU across the 2 processors?

On my dual PIII 550 running Linux it just does 2 WU's at the same time ;).

Search Marker
The orange marker shaped somewhat like a gun-sight represents the current position in the sky which is being searched. The location is also noted in the lower right corner in celestial coordinates (Right Ascension and Declination). You will see this marker move from point to point as the search progresses. Details on how we search for gravity waves coming from a particular source will be linked from here sometime in the future.

The instructions in this thread don't seem to work for latest Boinc release...telnet works and it reports success but no graphics. Any other suggestion?

I am running BOINC 5.4.9 on SuSE Linux 9.3. CPU is an old 400 MHz Pentium II. I can see graphics on SETI@home, Einstein@home, BBC.climate.change.experiment if I wish but not always on QMC@home. But I rarely use this feature because it slows an already slow CPU.

Is there any chance this project will just make the screensaver ready for Mac?

It is working on Macs (both PowerPC and Intel).
