I actually do average my RAC on my machines by pulling the data from statistics_setiathome.berkeley.edu.xml.



Yay, how I can do that?

I read the statistics_setiathome.berkeley.edu.xml file and pick out the values for <host_expavg_credit></host_expavg_credit> & I count the number of records to get the number of days.

There are probably better ways to do it, but I am just doing it with dos .bat scripting.

RAC(Recent Average Credit) is calculated very simply. Credit on the other hand uses a random number generator.

As you are using the stock apps I am guessing you want referring to the app_config.xml.

Let MemTest86 run at least 6 passes, you may get 2 or 3 passes without any errors but as the test continues the memory will warm up more and this is where errors may occur.

Cheers.


It has finished 6 passes with NO Errors so far , I will let it finish the 7th pass just to make sure...
It is almost 3/4 done with the 7th pass anyway.
This is really starting to be frusterating .
Something is causing this problem...

EDIT:
Ok , The screen shows 3 hrs and 40 min , Pass 8 , error 0 .

I guess that means it is on the 8th pass now... With NO errors so far.

This is with the old ram still in PC.

Not the NEW Ram...

I'm at a dead end...
I'll talk to Corsair tech tomorrow and see what I can do then...

I am running a memory test on some memory that was flagged as being bad by one of my other servers. As I replaced the pair and didn't mark which DIMM it was want to find the good one. However after running a memory test on it for the past week the software hasn't flagged the memory as bad yet.

Did I miss a note earlier, or am I the first to mention here that a 7th pfb_splitter is now online?

As of this writing, ~290,000 MB and 0 AP ready to send.

As of the 10 May 2013 16:00;34 Status Update, there were, indeed, 7 pfb-splitters shown and "Running", but only 6 were splitting MB. pfb-splitter 0 may still be in "proof" testing, or splitting for Beta.

Beta has its own status page. So I don't see why they would start a splitter for beta and put it on the main project status page.

Oddly enough beta seems to still be running mb splitters instead of pfb.

You could use PXE to boot an OS from a networked machine. Most NIC's I see these days for normal desktop systems can be configured for this. In the event you find hardware that doesn't support it you could maybe use a small flash drive to boot from and then load your preferred network OS image. I would expect many of the Intel Atom & AMD APU boards would support this. You can download the manual for the board to verify.

Another option would be to use a bootable CD/DVD or flash drive to load up your preferred OS. Then map a network drive to your networked machine for a working directory.

BOINC only writes to the local disc at intervals, IIRC the default is 60 seconds. So I would not expect disc activity to effect it much. I have BOINC on the same drive as all of my OS ISO images at work. With several machines pulling data to install OS's at the same time I have not seen any issues with BOINC on it.

Yes, I realised at work, this morning that XP was going to limit my choices and I'd be looking at something like the same Cat Suite I'm currently running (11.12) on my 4890, and I also had problems with the later Cat 12's drivers. I'm running quite an old version of SDK on the 4890...so I'd better look at running something a little less ancient!

It is also looking increasingly likely that before too long, I'll have to commit to something like Win7 64 bit....maybe dual-boot using a second drive, to keep the capability of still running all my XP32 progs. A pity in a way, as XP Pro has proved to be extremely stable for me.



I havn't found a program yet that I ran on XP that won't run on Win7 (both 32 & 64 bit) so you should be fine. ;-)

Cheers.

Sometimes Windows7, or Vista, may prompt with a message saying something like "This application has known compatibility issues, are you sure you want to use it". I just check the box for don't tell me thing again and hit yes. Otherwise I also haven't had any issues running apps.

However the 64-bit OS's will no longer run any 16-bit applications. So if there are some old 16-bit apps you are fond of you would need to dual boot for that purpose. Anther option would be to use a VM or something of that nature.

Do not be disturbed. The reason(s) that the Cricket graph is relatively low is because (a) AP units ready-to-send is zero, (b) the flurry of "shorties" has passed, thankfully, and (c) the Berkeley Boys are not currently pushing data from the offices at the top of the hill to the "co-location" on main campus.
This goes to show that if the SETI endeavor were still only MB (that is, no AP application), the bandwidth of the old connection was just barely adequate to do the job.

One or two years ago when just normal AR MB tasks were going out the 100Mb connection was sufficient. With bandwidth generally between 60-80Mb. The addition of higher computer power does seem to fit with the higher "base load". With more and more powerful hardware coming out it will be interesting to see how it reflects on the bandwidth. The implementation of larger workunits will also be interesting to see.

All is working well here at present, although Boincstats still has not received a stats dump since Monday.

Perhaps it will kick off at the usual time this afternoon.

The dump files are still currently dated Monday "06-May-2013 16:19". So in a few hours we shall see if they are updated.

Posted 10 days ago by Profile HAL9000
Ok, it's now at around 33% being 1057 hours into the WU. This is not working. I'm thinking that maybe even a shortie wouldn't make it for the deadline it'd be given.

Damn. :(

If someone gets the resend sent Friday and sits on it. Then you might still make it.
A Normal AR task might finish within the 7.5 weeks, but it looks like a VLAR's wouldn't be able to reliably make it in time. :(

I am using CAT 11.12 with my HD6870. I did try some of the CAT 12.x drivers, but ended up going back. As I was having some weird playback issues when using VLC. Some kind of dropped frames or stuttering. I haven't bothered with any newer ones since.

The current apps are built on SDK 2.6. So until that requirement changes I probably don't bother looking at the newer drivers.
I figure if it isn't broke, don't fix it.

Okay, panickers, what say you now?

MB ready to send is now upward of 245,000, still with only 6 splitters running. (FWIW, AP ready to send is about 2,000 with all its splitters running.)

Can we still say the MB/PFB splitters can't keep up with demand? Or is something else going on that's been causing the ready number to be so low recently?

Not convinced. They had real problems when (a) no AP was available, and (b) the MB work was mostly shorties. They are keeping up now with a better ratio of long/short MB tasks and the AP tasks. For example, I've received 364 tasks in the last 24 hours per BOINCTasks (staying at limits for the period). That number was ranging from 700 to 800 when we got almost all shorties, no AP, and the ready to send was depleted. Maybe there was a fix, but I'll wait and see.

I am wondering if they were perhaps stress testing the new pfb splitters. Then again it could have been since the number of results & wu's to purge had reached such a large number the creation rate was being limited to prevent the db choking again.

Sorry guys. I'm getting all the WU's right now.
5/6/2013 9:00:12 AM SETI@home Scheduler request completed: got 79 new tasks

That was one of my machines first request after getting "Not requesting tasks: project is not highest priority" all weekend and running down its queue. I have to saw BOINV 7 can really be pants about work fetch. Giving it didn't even check the 2nd project since the 30th of last month.

I saw that a few times, but wasn't sure if it was my old phone or the app doing it. I restarted my phone or the app and after the next checkpoint it corrected itself.

However the author of the app(s) might still be monitoring this thread: Seti android app.

If not you could submit a bug report on their website.

For some time I have been wanting to do something like this as well. Sadly I have not got around to it. It would be nice to have something to look at when I see one of my 5 i7-860 machines suddenly climbing in RAC when the other 4 are not, or when an obviously slower machine overtakes a faster one.

Posted 15 days ago by Profile HAL9000
Why I am running Lunatics 0.40 release, cpu and gpu. It works. Software without installation instructions does not work, obviously.

Using the optimized applications is targeted for the "advanced user" I would say. The installer packages they put a lot of work into helped branch out to less advanced users.

The updated apps released without installers are more along the lines of "advanced user" & the documentation provided with them reflects as such. If you do not feel comfortable with the level of instructions provided with the releases. Then the best option for you is to wait until the next packaged installer release.

The application obviously works & there are a number of people willing to assist in getting it up and going.

If you do want to use it you might want to try "I'm having trouble getting '_____' to work" instead of "This @$#&! doesn't work". I'm sure the later is not appreciated by those that spend their free time releasing these apps for us.

It is a game of hungry hungry hippos right now it would seem. With my 24 core box reporting a 3 hour queue it looks like it will be doing some PG work today once maintenance starts.

One shouldn't take XP support quite so lightly around here. From what I understand, someone around here is about to release software that doesn't support XP. As for Raistmers' new AP App, not only does it support XP, it also still supports my ATI 4670 in XP. Soon, you will see threads about missing XP support...

XP will be dropped for stock app. We can't load our undermanned SETI staff with support that AMD itself already dropped completely. They refuse to do anything (uninstall utility for example) for XP. As for HD4xxx btw.
So, we will try to keep XP compatibility while it will cost not too much. But after only already released binaries will remain...

When XP support is dropped, will we be allowed to Merge our XP Hosts to a different machine? I already tried to merge the XP from my Mac to a Windows PC, it didn't work. I will not be buying another version of Windows for my old Mac. So, I would of liked to have transferred the Host to a real Windows PC. Or even better, when OSX GPU Apps are finally released, merge my Mac' XP to OSX Lion on the same machine, that would work...for me :-)

You can not merge dissimilar hosts. However you can move your data to a new machine if you wish to maintain the machine ID.

Thanks for including XP in your new App.

What!? We get experience points crunching with OpenCL apps. Can I level up my Seti skill and crunch faster? :p

Yes we do. After a given amount of time you can unlock the Epic Power Bill achievement.
