21) Message boards : Number crunching : Panic Mode On (89) Server Problems? (Message 1575047)
Posted 3 days ago by Profile HAL9000
I would love to see one computer download gig worth of work. I wonder how long it would take to process a week on latest hardware running 24 7

Do you want a GB of MB work or AP work. Because a machine doing CPU & GPU can have 1.6GB of AP very easily when they are being produced. For MB 1 GB would be around 2700. Which was about the size of the 10 day queue on my 24 core server before the limits & when we were on MB v6.

Something that might be good to include would be price range categories.
Perhaps separated by 500 increments.
$/£/€ 499.99 & under
$/£/€ 999.99 - 500.00
$/£/€ 1499.99 - 1000.00
$/£/€ 1999.99 - 1500.00
$/£/€ 2499.99 - 2000.00
$/£/€ 2999.99 - 2500.00
Then larger values as the amount increases
$/£/€ 3999.99 - 3000.00
$/£/€ 4999.99 - 4000.00
$/£/€ 5999.99 - 5000.00
$/£/€ 14999.99 - 10000.00
$/£/€ 19999.99 - 15000.00
$/£/€ 24999.99 - 20000.00

This is interesting..

http://www.pcworld.com/article/2686115/nvidia-unveils-its-all-new-geforce-gtx-980-and-gtx-970-graphics-processors.html

the TDP for the GeForce GTX 980 with 4GB is just 165 watts.


Another article say 195W. Either way, that's still pretty good reduction

Despite the lower power consumption, Nvidia says the GTX 980 will deliver 5 teraflops of single-precision compute performance

24) Message boards : Number crunching : Max temp for getting the normal life out of a video card? (Message 1574476)
Posted 4 days ago by Profile HAL9000
I'm getting too hooked on this stuff. I just bought a dell with a r9 260 as my graphic card and I just swore the other day I wanted out of the dell hook up.
But I saw this pretty little thing for a nice price and I just had to do it.
Didn't even have a choice. That's it, no more stuff.

You might want some ointment. As it seems you have been bitten by the bug.

Interesting stair-steps on the Crickets right now.


Yes, in Daily Graph. But when looking at Monthly Graph I see transfers are going back to "normal" and above it, no more AP frenzy???

Just my guess...

If you look at the monthly graph you can see our "normal" AP frenzy traffic. Which is often about 200Mb. The past few weeks there was an uptick in the inbound, first small and then larger, and outbound even went up over 400Mb at one point. It looks odd even on the yearly graph.
26) Message boards : Number crunching : ntpckr questions (Message 1574465)
Posted 4 days ago by Profile HAL9000
My understanding is.. they got a donated, spec-built server specifically for ntpckr to be run, but shortly after firing that process up, it just about crippled the science database, so it was turned off.

Then work (and more hardware donations) began on improving the I/O throughput for the database, and we now have the hardware for the database server that can handle immense I/O loads, and then it was discovered that the I/O limitations are the software itself (or the drivers for the hardware), which needs tweaking and fine-tuning, or for alternatives to be found and tested and eventually deployed.

This is the stage where I believe it still is. I believe it was generally decided that the database software was not particularly designed for a database as large as what we have, so we are in "uncharted territory" so to speak.


However, I have suggested once before that if ntpckr is such a load on the database, why not use a copy of the weekly back-up and put it directly on the ntpckr machine and let it chew through that for however long it takes for it to get "caught up," and then throw an incremental update to the database at it and it will chew through that in short order, maybe do one more incremental update, and from there, it should be able to handle "near real time" with minimal impact.

But.. I don't know if that's even a feasible option or not.

I think Matt had mentioned they were looking into splitting the DB into smaller chunks. So that they could actually work with it.

I only run one task at a time. The temps are 58-64C. The fan on the r7 I leave at 100% since it runs fairly quiet. The 7770 fan is usually around 70%.

I think Hal told me to only run one task at a time on my cards, if I remember correctly, but it was kind of hectic back then. You get the problem where the gpu's get slowed down by those heavily blanked tasks and have to rely on the pace of the cpu's.

Even if it was someone else. For these range cards it is probably good to run only 1 AP at a time. If the non blanked tasks are keeping the load up pretty high more than 1 isn't really a benefit. Also when mixing GPUs you either have to setup for the slowest one or run multiple instances of BOINC.

I leave the fan on my HD6870 on auto. On a hot day with the windows open the fan spins up to about 55% from 40-45%. While keeping the GPU at the same temp as when the A/C going is on. I would have to check the temp logs but I think it stays well under 60ºC all of the time.
I leave the fan on auto to hopefully get as much life out of the fan as possible. Because a dead fan is a fairly likely way to have a dead GPU.

I just wandering why they skip the 800 series.

I think maybe to cause a better separation between different segments. Like Radeon R3, R5, R9 series GPUs. Perhaps they will keep some as 700 series. Then introduce new mid range GPU as 800 series.

Yes the blue cricket line certainly has been under an unusual load over the last week or so, but then my GPU's have been doing a lot of MB shorties lately too.

Cheers.

I wonder if they are doing something with one of their other servers in the colo. As I recall they moved over all of their servers from the closet. Which included other things besides just the SETI@home gear.
A solid 150Mb, in both directions, is a lot of data the past few days.
30) Message boards : Number crunching : Computer crashes a lot (Message 1572851)
Posted 7 days ago by Profile HAL9000
As a work around until this is sorted out you could configure the machine for auto logon. That was when it crashes it will log in and restart BOINC. Running control userpasswords2 is one way you can setup the system for auto logon.

The information WhoCrashed is giving you is located in the Windows Event log. You don't really need a 3rd party application to read it, but whichever way you prefer works.

That error doesn't point to anything specific. Kernel crashes can be tricky to lock down. If you look in the windows event log are there any event prior to the crash that may show what the system was doing. Perhaps an anti-virus scan or something along those lines was running?

In another post Raistmer was mentioning it would be nice if we had a per GPU config and I made this suggestion. Perhaps one of the Lunatics forwarded it or a better idea to the BOINC devs.


I think that would be a great option if they could do it. Nice to know both of you were thinking already about that. Guess I'll wait and see if anything comes from that.

Zalster

If you are on the BOINC Alpha list you could mention it also. I would think that the more times something is mentioned the more likely it is to happen.

What about using the <coproc> inside of the app_config file. I was looking at that and trying to figure out if I could add that into the app_config and tell it if GPU 0 or GPU 1 then run this many, if GPU 2 or GPU 3 then run this.. I'm not sure how to fix it into the app_config. What I was thinking was along these lines.

<app_config>
<app>
<name>astropulse_v6</name>
<coproc>
<type>GTX 780</type>
<count>2</count>
<device_nums>0 1</device_nums>
<gpu_versions>
<gpu_usage>0.5</gpu_usage>
<cpu_usage>1</cpu_usage>
</gpu_version>
</coproc>
<coproc>
<type>GTX 750</type>
<count>2</count>
<device_nums>2 3</device_nums>
<gpu_versions>
<gpu_usage>1</gpu_usage>
<cpu_usage>1</cpu_usage>
</gpu_version>
</coproc>
</app>
</app_config>


Ok, I don't do code so I don't even know if what the above looks like is even remotely possible but that is why I am asking. Last thing I want to do is put this in the computer and have it go berzerk. Thoughts and Ideas?

You can add whatever you like to the app_config.xml. However since there is no code to read your made up values they will be ignored. With <coproc> declared twice I imagine the last one will take effect.

33) Message boards : Number crunching : various gpu card manufacturers (Message 1572708)
Posted 7 days ago by Profile HAL9000
I see now that the various card manufacturer's of video cards, Sapphire, MSI, XFX, etc. show different ratings for gpu core clock speed and single precision GFLOPS. I haven't found a source where you can compare one mfg. to another. Does anyone know if there is one and where to find it?


Do you mean like this?

http://www.tomshardware.com/reviews/gaming-graphics-card-review,3107-7.html

I think they are looking for a roundup comparison along the lines of: 10 Radeon R9 270 And 270X Boards, Reviewed. Unfortunately not a lot of review sites do very many of these kinds of comparisons.
I think mostly the manufactures don't want to show that when you pay an extra $80 for that slightly overclocked card you are only getting 0.021% more performance.

The easy way to do that is start 2 instances of Boinc on the same host, each one optimized for one of the GPU´s.

I don't think anyone except you calls that 'easy' :P - though I don't doubt it's effective, but with side-effects.

It is pretty easy to setup, but BOINC can be rather temperamental in that situation. I had a few issues the last time I was doing that with BOINC 7.0.64.
-Sometimes an instance would generate a new CPID
-Tasks run on one instance would be reported as valid on the other running instance.
-One instance would just stop running tasks with no log as to why. To get it running again all BOINC instances would have to be stopped and then started.
I figured I might try it again with a newer version at some point.
35) Message boards : Number crunching : blanked AP - faster or slower (Message 1572443)
Posted 8 days ago by Profile HAL9000
I'm not sure you could actually force BOINC to only run highly blanked tasks on one of two GPUs. Well not without constantly micromanaging the system task by task.
Any efficiency gains would probably be lost in the constant stopping and starting of tasks to try and move them around.
36) Message boards : Number crunching : crossfire or sli? (Message 1572441)
Posted 8 days ago by Profile HAL9000
Those features are used to make your collection of GPUs work as one for rendering purposes. Where the slight lag between the devices talking to one another isn't very noticeable.
In the case of BOINC & SETI@home you are preforming a separate function on each GPU. Having a single task processed across several GPUs may cause a massive slow down in processing while data moves across the PCIe. Instead of internally on the GPU.

In the past I think you actually needed to disable those features in order for BOINC to use all of the GPUs. However with newer drivers I think it no longer matters.
37) Message boards : Number crunching : I have one screw missing! (Message 1572200)
Posted 8 days ago by Profile HAL9000
OP: every single screw attaching the board to the mounting points is not 100% mandatory. Yes, you should use them all, but you don't have to. The ones around the edges are the most important, so just take one from the middle somewhere and move it to the missing one on the edge.

Sometimes not all of the stand-offs are for screws & there could be some that a guide posts.
I had forgotten about them until I was swapping out an older microATX with a mini-ITX the other night. I put the board in & looked to make sure I had 2 of the 4 holes lined up. I loosely put in 2 screw & then started to make sure the rest were lined up. I got to the post & my brain just stopped for a moment. Saying "one of these things is not like the other".
38) Message boards : Number crunching : new computer build (Message 1572193)
Posted 8 days ago by Profile HAL9000
It's been a while since I did this (mainly in the Windows 2000 and XP days), but my understanding then was that the Dell-branded re-installation CDs contained a BIOS check program. If the CD was run, and found a Dell BIOS, then the combination was automatically licensed and didn't need to go down the product key/activation route.

I still run a Dell Precision workstation which was supplied with Dell OEM XP pre-installed. I upgraded it to Vista using a Dell-supplied upgrade DVD (the hardware was already Vista-certified before I bought it - just that the OS hadn't been officially released), and I upgraded it again to Windows 7 using a Technet evaluation DVD and Technet-supplied product key. It's still running with the applications I first installed in 2006.

So it can be done, but there are so many possible permutations it's hard to predict how it will turn out in any particular case, with any particular combination of OS versions.

(My workstation went from XP Pro --> Vista Business --> 7 Ultimate. Remember that with Vista and 7, you can't mix Home and Business/Pro versions)

I have not had that happen on any systems I worked with. Perhaps it is another one of those differences in configuration between the US and UK division? As we have seen in the past with drivers supplied with their systems and such.
Perhaps it could have been retrieving the activation information from the Dell utilities partition? That is something I have always done away with when redoing a machine.

Dell puts the Microsoft OS key on the outside of the case

But that means anyone that have physical access to the computer can steal the OS key? (e.g. by making photo)

Having someones key that has been activated doesn't do you a lot of good. If you try to use an already activated key on another system. You get prompted to call MS and provide more information before activation occurs. Last time I did that it was automated, but it took ages to punch in everything on the phone keypad.

If I am reading you correctly, I would have to go thru dell and their support $. I really don't want to go that route. My last computer I built myself, which I really didn't think I could do without a failure. I wouldn't want to get in another tie-in with a hardware mfg. if I can avoid it.

Dell puts the Microsoft OS key on the outside of the case. As per Microsoft's policy for OEMs to do so.
