http://www.zdnet.com/article/microsoft-starts-pushing-windows-10-as-a-recommended-update/

Microsoft is stepping up its Windows 10 push by making the OS a 'recommended' -- though not required -- update for Windows 7 and 8.1 users, beginning February 1.

I think at least one of my machines is perfectly safe from the Windows 10 "update".

Since BOINC doesn't have a boinccmd.exe option to adjust CPU usage on the fly I did this.
-Make copies of cc_config.xml with desired <ncpus>N</ncpus> value
cc_config.1 = <ncpus>1</ncpus> cc_config.2 = <ncpus>2</ncpus> cc_config.4 = <ncpus>4</ncpus> cc_config.all = <ncpus>-1</ncpus>


-Have a script to copy desired cc_config over cc_config.xml & then tell BOINC to update.
copy cc_config.2 cc_config.xml /y boinccmd --read_cc_config


You could then automate the whole process.
set boincdir=z:\BOINCdata pushd %boincdir% copy cc_config.2 cc_config.xml /y boinccmd --read_cc_config start /wait notepad.exe copy cc_config.all cc_config.xml /y boinccmd --read_cc_config

Your post slready contains my answer HAL9000.

I wasn't sure how much of that was true & how much was sarcasm.
But it seems you have removed BOINC for now. Which means you are not longer having the issue.

Well Alf, It is Alf, right? I clearly stated what the problem was and what I was seeing. Very clearly. That is what the original post was. Nothing about Lunatics, anyone named Nez, no conspiracy theories, no pretending to be anything, no personal attacks, none of that. We will wsit while you reread it.... ....... ...... .... [*hums completely off tune*]
So, I clearly stated what I saw as the problem and what I wanted. Very clearly. Since then, I got rid of the v7 problem by destroying the v7 work units it kept downloading. Unconventional but effective! And done without conspiracy theories involved! [*wolf whistles*] It did happen to involve my hard drive being destroyed and not downloading BOINC again to the laptop yet, and factory reset destrying everything on my phone, but the damned v7 units are gone. 8)

Are you still having the problem of v7 tasks being downloaded? Did you manage to abort the v7 tasks your machine did download?

Hi folks! I just tripped over AP WU 2027678046, which I was assigned to crunch. Those two identical intel GPUs trashed the WU for exactly the same reason and they also failed with several other WUs. Maybe developers should take a look.

Intel has a habit of releasing new drivers that do not work well for some BOINC projects. There are several older iGPU drives that are known to have issues with SETI@home & Einstein. So a driver issue could be one possible reason.

Both of those hosts are using HD 4600 iGPUs on Windows 10. One is an i5-4690K with driver 10.18.15.4256 the other is an i5-4570 with driver 20.19.15.4331. They both had an issue at the same spot for that WU. ### Restart at 44.14 percent.

You might want to save a copy of the wu file for the devs. They may want to have a look at why the app choked on that file.

I have had a bit of a (slightly one sided) talk with David about this.

His answer to me is true, but a bit besides the point I was making. Haven't heard back yet on my latest proposal. ;-)
When a scheduler request asks for zero seconds of CPU, there are many possible reasons.
Project prefs are one.
Or the CPU queue might be full.
The scheduler request doesn't say what the cause is.
Not worth changing this.

It does seem to be a rare enough occurrence that digging into why it sometimes happens wouldn't be a good use of time.

If a seti program crashes it can reveal your username by listing your user path in error report. I have seen that happen.

Most people who register here do so with the name they're using on their computer, as by default that's what the web site will look for and use. Only those that go into their account and edit other account info know they can change their forum and Account name.

Also, a lot of the error paths are from the system that compiled the science application, so in that case the path can give the application developer's name.
Or indeed if the user compiled the app themselves, their name.

It is true that BOINC writes certain log files to C:\Users\Windows account username\AppData\Roaming\BOINC\, but as far as I know that path is never shown in app crashes. BOINC crashes are registered in the stderrdae.txt log file that's written into the BOINC data directory, which on Windows XP and 2000 is written to C:\Documents and Settings\All Users\Application Data\BOINC, and in Windows Vista through 10 to C:\Programdata\BOINC\, thus not giving a path with a username in it either.

Not saying it's not true, mind.

I have seen my windows username appear in a Stderr output from a crash dump before. Not that I really mind. Anyone can call call me what whatever they like. I imagine there are some that would prefer that not to happen.

The helium drives are meant for sequential reads/writes. They have pretty good performance for doing backups, but fall flat on their face when you do small, random seeks on them.

If you want a fast mechanical platter drive, you'll want 10k or 15k RPM, but the down-side is that the cost/gb is not that great.

I know the WD Black 4TB drives do about 175MB/sec read and about 150MB/sec write, thanks to the high data density. Those are pretty good speeds for 7200rpm.

I've been wanting to get something bigger/newer than the five 1TB Blacks I have in my external enclosure, but the reviews across all brands for anything over 2TB do not fill me with much confidence. Apparently, Quality Control is no longer a priority like it used to be. That being said.. I would recommend doing a complete system image once you get Windows installed and get all the updates and drivers you're interested in. Make the image, store it somewhere (another HDD, a flash drive that is big enough (probably 32gb), etc) so that IF the drive dies unexpectedly, when you RMA it and get the replacement, you can just reload that backup. And I would make frequent backups of the personal data that you don't want to lose.

That's the problem that I find with large-capacity drives is that when they die.. you lose so much data (unless you have backups). That's kind of why I like having 5 1TB drives, because if one dies, I only lose at most, 20% of my data, assuming none of it is backed-up (which most of it actually is).


I like the idea of SSDs, and they are getting cheaper and more capacity, but I honestly don't find a huge difference with them. Sure, system boot time is pretty quick, but once you're at the desktop.. I honestly don't notice much of a difference between SSD and the old 80gb WD Caviar that only did 35MB/sec. I guess it would be more significant if I booted-up and shut down frequently, but I generally go 15-40 days between restarts. So.. yeah, SSDs are nice, but cost/gb still isn't close to what mechanical drives have to offer. Not yet, at least. Give it another year or two and we'll start seeing 3 and 4TB SSDs for $300-400.

As far as I know WD is the only manufacture to ever make SATA drives over 7200 RPM. Which is my I mentioned SAS drives for 10K & 15K previously. Something like the a Seagate ST1200MM0158 (1.2TB 10000 RPM 128MB Cache SAS 12Gb/s) might suit their boot disk needs.

I would hazard a guess that this might be for their new gaming machine being built. For games that load a lot of data while playing you really want the fastest drive access you can get. Otherwise you may have to deal with frustratingly long load times from maps or waiting for menus to open.

Like you mentioned. Losing large amounts of data when a disk dies is one of the problems with a single large disk. So for any of my personal storage over 1 TB it goes into a RAID1 or RAID5. Then I backup my OS with a disk image to my RAID storage. For my needs, & budget, I'm OK with using the "fake RAID" from the chipset controller. My current gaming machine uses an inexpensive sandisk 480GB SSD & a RAID5 array using 3TB WD Red drives for my backup/archiving/media storage.

If you look at the Stderr output you will both of these tasks resulted in
SETI@Home Informational message -9 result_overflow NOTE: The number of results detected equals the storage space allocated.

Which are not really good results to compare. If you compare non overflow tasks you will find they average closer to 15,000 seconds for a task while you are averaging closer to 20,000 seconds.

Looking at the actual Run time instead of just the CPU time there is much less difference.
Run time CPU time 74.44 70.89 69.44 57.20


Another thing to note is since they are using their iGPU to process SETI@home work their CPU times are roughly double what they would be if using their CPU alone.

Everthings i tried in Lubuntu turns into a failure.

NO, NEVER 1 task for this gpu will, or were be loaded.

Sa 30 Jan 2016 19:24:54 CET | SETI@home | Scheduler request completed: got 0 new tasks

Is that host actually requesting GPU work?
Something like "SETI@home Requesting new tasks for CPU & ATI GPU"

On our "account" page, top right corner, there is a place for "badges".

I've only seen one badge, which is the "one percent" badge, which I have.

Are there others?

Wasn't able to find any more on this website.

Yes. There are 1%, 5%, and 25% badges.

If you want the same performance as a WD Raptor in a HDD the you will need to look at SAS drives instead of SATA. SAS drives have several spindle speed options but you would probably only be interested in 10K & 15K RPM models.
Depending on the number of SAS ports you need. You can get a SAS controller that only uses a PCIe x4 slot.

Personally I went from raptor drives to SSD. You could use 2 SSD in RAID1 if you didn't trust them. A slow SSD is still faster than the best HDD.

Posted 16 days ago by Profile HAL9000
HAL, I partly hear what you are saying. One thing I can't understand is why do I receive CPU work for MB work units when I don't have any CPU option selected for that particular profile. If you remove part of your app_info file that would mean that you couldn't use that particular application at all wouldn't it? I certainly don't want to do that

One guess I have is that somewhere in the work fetch process the server gets confused and just sends whatever it can to fulfill a request for work. Maybe it is an issue reading the users preferences from the db during the work fetch request? I haven't seen this behavior with other projects, but not many of them get their servers beaten as hard as SETI@home.

From your first post it seems like you want to run:
AP: GPU & CPU
MB: GPU
If that is correct I would only need to have those 3 apps installed.

If you like to switch CPU MB off & on then it makes sense to leave the MB CPU installed. However sometimes the server will sneak you work for other apps despite your venue settings.

I have a theory that since we don't have a linux mb cuda v8 gpu app yet, that's where most of the aps are going to

Blaming Linux is as good a reason as any but without data to back it up I would demote it to a hypothesis.

The 3 linux boxes on the first page of the top hosts list have very few AP. All of the windows boxes seem to have about double the number each linux box does.

I was just investigating my last failed unit on the same system...650ti...and it said that it had 8 spikes and 7 triplets, but bad computation. One of the completed okay units done by someone else said 8 spikes and 7 triplets but it finished fine. How does this work? If we both found the same thing, why is one bad and one okay? Just trying to learn.

Allen

When you see in the stderr_txt is not the actual result data that is being compared by the server. It is just kind of a summary.
The spikes could have been found in different places or their power levels could be to different to be a match.
37) Message boards : Number crunching : Delayed validation (Message 1760171)
Posted 16 days ago by Profile HAL9000
My account shows four SETI V.7 WUs awaiting validation that are more than a month old. Two were sent Jan. 1, one is from Dec. 28 and one is from Dec. 19 -- 6 weeks old, although the deadlines are still two weeks away.

These last two are with the same wingman.

My question is this: Is it advisable, ethical, recommended or just uncool to send my wingmen a message to get on with it already, finish the those WUs so my four validation pending WUs can be cleared?

Am I being too picky or demanding here? Should I just keep my mouth shut (at the risk that they will be invalidated because they won't get sent before the deadline)?

Just askin...

Stevie G.

A task is only marked as Invalid if the result data does not match the other tasks created for the workunit.

I had some tasks I completed in September validated last week. Because it took a few resends & timeouts to get someone to send in another good result. Which is perfectly acceptable for the project. If the project needed data back more quickly there would be shorter deadlines or other processes in place to ensure results get returned more quickly.

Am I being too picky or demanding here?

Basically yes. You are free to raise any concerns you feel you need to. This is just something many users whine about & hasn't changed over the past... when was BOINC launched?... 14ish years?

Just to double check: you are picking "HOME" before this happens, and it is set to "AP" only, "Other Work" unchecked?

EDIT: Or are you switching to default, which looks like you have it stated/set to do Any Work (all boxes checked).

Yes this happens after a switch to default from home with allow work in Boinc manager selected.

Yes you are correct I have all the projects selected but I do not have the CPU option ticked on the my default profile.I only have use CPU ticked on my home profile and I only have AP work selected.

On both the default profile and home profile I have the following: If no work for selected applications is available, accept work from other applications? set to no

I'm pretty sure what you are seeing is the same reason I get: SETI@home Message from server: Your app_info.xml file doesn't have a usable version of SETI@home v8.
On my hosts that have their venue settings configured as:


Which for me is nothing new. I've been seeing this behavior for years.
Which is why I don't truest the venue settings 100% and modify my app_info.xml to make sure I'm only running the apps I want.

The information on https://setiathome.berkeley.edu/sah_porting.php looks out of date. So you might need to get the source from lunatics if you are going to roll your own.

Since quite a while back, Lunatics sources are hosted at Berkeley too:
https://setisvn.ssl.berkeley.edu/trac/browser/branches/sah_v7_opt
or do an SVN checkout as described on the porting page.

I didn't see anything for v8. That's why it looked out of date to me.

Posted 17 days ago by Profile HAL9000
I have been running the Lunatics Intel GPU app here and the stock Intel GPU app on Beta, on an HD 4600, using the most recent driver (version 10.18.14.4264, dated 4 August 2015), without encountering any problems at all.

Thanks John, good to know that version works as well - at least for SETI.

If it's working, I'd leave well alone: but technically speaking, it isn't the "most recent". Looking on the Intel web site, I found

Version: 15.36.28.4332 (Latest) Date: 12/11/2015

Unpacking the zip, the internal documentation describes it as

Release Version: Production Version Intel(R) Graphics Driver: 10.18.14.4332 Intel(R) Display Audio Driver: 6.16.0.3174 Package: 514951 Operating System(s): Microsoft Windows* 7 64-bit Microsoft Windows* 8.1 64-bit Release Date: November 30, 2015

(separate 32-bit versions, and versions for Windows 10, are also available. The discrepancy between download version numbers/dates and driver version numbers/dates continues to irritate me.)

This is not a recommendation to upgrade: more a reminder to myself that perhaps I ought to test it, both here and at Einstein, before the next installer release.

Their versioning does leave something to be desired. From my rough observations this is what I'm finding.
15.33.xx.xxxx (driver 10.18.10.xxxx) 7th generation iGPU. Ivy Bridge, Haswell, BayTrail.
15.36.xx.xxxx (driver 10.18.10.39xx & driver 10.18.14.4xxx) 7/8th generation iGPU. Haswell & Broadwell.
15.40.xx.xxxx (driver 20.19.15.xxxx) 9th generation iGPU. Skylake.
