21) Questions and Answers : GPU applications : Astropulse ATI not stopping on PC use (Message 1365728)

(seti stops correctly its just astropulse ATI that doesn't)

Well, that shows it's not a BOINC problem, but an application problem.

Check in Windows task manager that boinctray.exe is running and make sure that your BOINC Activity is set to Run based of preferences for CPU and GPU.

I'm running 12.4 on my HD6850 - 2GB. It's been running Einstein BRP4s ever since. No problems.

Just an example as to why 7zip is great: its compression over zip.
I have a (transitioner-log) text file that's 18,991KB big. Using the 7zip archiver, I compressed it twice.
Using ZIP format, compression Ultra, compression method deflate, dictionary size 32KB, wordsize 256, this file compresses to 354KB.
Using 7zip format, compression Ultra, compression method LZMA, dictionary size 32KB, wordsize 256, this file compresses to 193KB.

We know why we use compression archivers, it's to make these files smaller on disk, but also smaller to download. I'm sure some of us don't mind if a file is 19 Megabytes or 193KB, since we have unlimited download capacity over a big download pipe. But not everyone has that, so when every byte counts towards your cut-off at the end of the month, the better compression is what counts.

I was expecting instructions along the lines of: Copy file A to directory X, copy file B to directory Y, run file D, etc.

Like this?

If you want to do anything more than bitch and moan go to the BOINC boards and talk to David and Rom.

Who aren't there, unless I ask them to come check out thread such and so. But this might be a thread I do not want to burn my fingers on.

I do maybe every other day shut down the computer, mainly just to let it cool down and give it a "break."

If your CPU gets hot, it may lack sufficient cooling, which may in turn cause crashes and work here to err. Shutting it down to let it cool down and then starting it up again won't help, as as soon as the CPU is under load again it'll heat up again. It won't get hot gradually, but almost instantly.

By hot, I mean anything under its maximum of 100° Celsius, but above its normal operating temperature of ~34° Celsius.

If this is a laptop, look at cooling pads (example given) to add external cooling to the CPU.

If it's a desktop, shut the computer down and open it up. If there's a lot of dust in there, that's causing the heat to be trapped. Removal of the dust is then adamant. Be it by yourself, if you dare, or by a computer-repair company. But the latter will charge money for that.

While at it, you may also want to see if the cooling that is on the CPU is adequate. If no fan at all, for instance, the cheapest of fans will do wonders already.

29) Questions and Answers : Windows : BOINC Not uploading/reporting (Message 1363228)
Posted 22 days ago by

BOINC will automatically report the to be reported tasks, but it does only do so at least 24 hours after the first task was ready to report. Why not do so immediately? Because it adds to the server overhead.

Reporting 1 task takes as much overhead (database reading and writing, memory usage, CPU usage) as does reporting 10 or 20 tasks. So it's more efficient to report multiple tasks.

So, then, completed work is reported at the first of:

1) 24 hours before deadline.
2) Connect Every X before deadline.
3) 24 hours after task completion.
4) Immediately if the upload completes later than either 1, 2, or 3 upon completion of the task.
5) On a trickle up message.
6) On a trickle down request.
7) On a server scheduled connection. Used, but I am not certain by which project.
8) On a request for new work.
9) When the user pushes the update button.
10) On a request from an account manager.
11) report immediately every task, if "No new Task" is set.
12) report immediately if CPU or network time-of-day override starts in the next 30 minutes. (BOINC 7.0)
13) When minimum work buffer is reached. (BOINC 7.0)

Well, that was all the advice I could offer. You see the rest of the graphics, which means that OpenGL must work correctly. Just the graphics app that doesn't seem to work correctly.

I wonder what happens if someone builds it against a newer OpenGL API.

It's a glitch in the OpenGL graphics. Normally it can be fixed by exiting the graphics/screen saver and starting them again.

But it can also happen if you set the "switch between screen savers" time too stringent. Allow for enough minutes between switches, so the OpenGL driver can initiate correctly.

And know that the graphics and screen saver are just pretty pictures, They're not required to run Seti or Milkyway@Home.

33) Questions and Answers : Unix/Linux : How to save a task if you change OS (Message 1362632)
Posted 24 days ago by

No. Tasks are registered against the computer they (are going to) run on. The computer ID that downloaded the work will also have to upload & report them.

No two computers can use the same hostID. In a computer ID the operating system is registered, so that the scheduler can send the correct science applications to that hostID. By switching from Linux to Windows you change operating system.

So the host you now run on will be getting a new hostID, due to the switch to a other OS. Meaning that the new hostID will not be able to upload any finished work registered to the old hostID.

You can either:
1. Set No New Tasks and run the cache empty, upload & report all work before switching to the other OS.
2. Set No New Tasks and abort all work in cache, then switch to the new OS.

35) Questions and Answers : Windows : requires reboot... again and again and again (Message 1362297)
Posted 25 days ago by

It sometimes happens that the RebootPending.txt file in the BOINC Programs (C:\Program Files\BOINC\ or C:\program Files (x86)\BOINC\) directory gets stuck there.

By the way, perhaps time to update to 7.0.64? It's the new recommended.

36) Questions and Answers : Windows : Boinc is using 100% of my CPU's (Message 1362016)
Posted 26 days ago by

Ageless

That's normal. It'll also do that at low priority, meaning that whatever other program asks for CPU cycles, it will get, as Seti will then use less than 100% cycles.

If you mean, it does it while I use the computer and it never did that before, then your preferences changed to from "do work when computer is in use -> no" to ".. -> yes". You can change that back to no. Default is no. Default BOINC will only allow science applications to do work when the computer is idle (no one at the keyboard or moving the mouse).

If you mean, it's started to produce errors, then you better check what's causing that. Could be heat. And heat is usually produced by a clogged up CPU fan, where dust bunnies have grown into. Can easily be gotten rid of with a can of compressed air and an old toothbrush.

And you don't really have to remove Seti when things go awry, just exit BOINC (File->Exit BOINC->Check "Stop running applications when exiting Manager?"->OK). That'll already calm things down on the CPU cores.

We don't know what your internet connection is and what else you may be doing with that internet connection. For all we know you or someone in the house is downloading or uploading Gigabytes of torrents at this time and you didn't tell the torrent program to leave bandwidth free.

The 2600 does show up in Windows though.

There it'll have drivers that make it CAL capable. It still isn't OpenCL capable, not even under Windows. So you can only run the Brook-hybrid app on it.

BOINC is only seeing the PC 4670, not the Apple card?

The Radeon HD2600XT is not OpenCL capable, only CAL capable, and that may not be / no longer supported on the Mac?

Depends on what you wanted to go do there.
See the contents of your app_info.xml? Then continue onward to C:\Programdata\BOINC\projects\setiathome.berkeley.edu\ and open the app_info.xml file in Notepad. You don't need a fancy XML editor for it.

Then if you want you can copy and paste the contents here.
