21) Message boards : Number crunching : WinXP EOS -> it's really unsafe after April 08, 2014? (Message 1500557)
Posted 12 days ago by Profile HAL9000
If your PC is on 24/7 with a router then you are pretty well protected from inbound attacks. Someone could find an exploit in your router, but do you replace your router just because the maker stops releasing new firmware for it?

If there was a big exploit that could be used to cripple XP machines there is no good reason why someone would wait until after the 8th to attack it. Microsoft often takes weeks, months, or never bothers to patch something once it has been publicly known. Companies that are still using embedded XP have service contracts to have their OS's patched anyway.

As far as getting bad things from the web. Your browser is your first line of defense. If something gets to your machine then they used an exploit in the browser or your settings allowed it in.

I'm not sure why you are not getting any updates. The machine we use in the lab at work to copy CD/DVD's is running XP & gets them regularly. I have it setup to prompt when there are updates. So I can uncheck the microsoft malicious software thing.

The only safe computer is one that isn't connected to power.
Also XP has a declining market share. So that makes it a less desirable target all of the time.

On 16 April, my new build will commence to replace the dead i7/930 (Intel i7/4770K, AsRock Extreme4, Win7 ultimate(64-bit), 4 x 2GB Corsair Vengence ram, 1 x EVGA GTX660SC @ 2GB, 2 x Samsung 840Pro 128GB SSD, 1 x WD 250GB HDD, 1 x UltraX4 1200 watt PSU, BOINC 7.3.15(x64), Lunatics 0.41). The GPU will be processing 2 x AP OpenCL, or 2 x MB, or 1 x AP & 1 x MB depending on availability. I will be adding another GPU as soon as possible.

I've read most of the posts on incorporating the IGPU into OpenCL processing along with GPUs, but what I've not seen are experiences concerning what happens when games or DVDs are being used. I normally have suspended GPU processing when doing either of them to prevent stuttering, etc., and there have been times when my bowser has froze because of GPU processing. My questions are -- Wouldn't it be better to use the IGPU exclusively as the monitor, ignoring it in BOINC, so that the AP/OpenCL processing will not be interrupted during those times that games/DVDs are being used?

On my i5-4670K HTPC I have the HD5750 connected to the TV via HDMI & not running any tasks. Then I have 3 CPU + the Intel GPU running. No monitor on the Intel GPU. Sometimes when watching youtube, or videos using VLC, I have to pause all processing. As there is stuttering or the video pauses for several seconds while the audio continues on.
I am starting to think the memory bandwidth is getting maxed out or something of that nature.

Thanks for the reply,
On both of my i5-4670K machines I am using the Intel graphics for crunching. Initially I didn't plan on even enabling the built in GPU but then saw how efficient they were.
On my gaming machine I run 4 CPU + the Intel GPU. Then on my HTPC I run 3 CPU + Intel GPU. I free up a CPU on that system because of the various thing I do slow down SETI if I run 4+1. For both system I use the PCIe card for the display.

Are the Intel GPU's you mentioned the integrated ones, or plug-in cards?
What plug-in GPU cards are in your boxes?
No dummy plugs are needed on the Intel connectors.

What OS are you using?
Did you need to do anything special for the system to recognize both GPU's?
It is also only doing MB instead of MB+AP like my gaming box.

I am doing both MP and AP workunits on all 4 of my boxes.
Thanks, Ron

They are the integrated GPU's. Intel has not made an add-in card in quite a long time IIRC.
For the add-in cards I have a Radeon HD6870 & HD5750 at the moment. Both are running Windows 7 x64 like your machines. You can get the full machine specs from the links I put in the previous post.
Also if you need help on adding the Intel displays for BOINC to detect them. Try this quick write up I did with images.

New, cheaper, 64-bit MinnowBoards coming out from Intel too. Including GPUs on die. Whether they'll be any use for s@h, I don't know...

I wonder if they will update the Galileo as well. You can get one of those for ~$50 right now.

According to the graphs, Results received in the last hour remain fairly steady, Awaiting validation is fairly steady, yet in my account the Pending validation continues to climb, significantly.

Grant, with your latest upgrade it's only to be expected that your pendings will go up (take a look at the pendings of my 2 main rigs). ;-)

I was expecting it, I'm just surprised they've gone up even more. They used to be around 500 or so, then it settled down around 750, now it's up to 830.

Since the change to v7 I tend to have more valid than pending across my 30 machines.
27) Message boards : Number crunching : 780ti not faster than a GTX 580 (Message 1497959)

It depends on what they are doing to the GPU. If the kind of processing they are doing is saturating another resource then a faster GPU won't help that kind of processing.
28) Message boards : Number crunching : AMD GPU need DVI dummy plug with Win8.1? (Message 1497356)
Posted 19 days ago by Profile HAL9000
I wouldn't expect Windows 8.x to respond much differently than Windows 7.
Using Windows 7 & Cat 13.12 I do not require dummy plug to use my HD6870 when only the Intel GPU is connected to a monitor. I normally run the opposite configuration but just switch it around to test. Did manual detect & then "Try to connect anyway on: VGA".

Also the resisters for a dummy plug should be 75ohm but anything from 68-100 is acceptable. The ones shown in that link are actually 47ohm. 68ohm would be blue gray black
29) Message boards : Number crunching : 120mm fans with ~ 59CFM / 100m3/h (installed) (Message 1496747)
Posted 20 days ago by Profile HAL9000
I have taken a chance on NZXT recently. Using their Source 220 case & some of these.
http://www.nzxt.com/product/detail/94-fz-120mm-non-led-case-fan.html
I added one in my NZXT case & one in my HTPC. Which are both my i5-4670K systems.

Even if there was not grill or filer on either side of the fans. Once installed in a case I imagine they total CFM would be still be less than free air tests. However, Depending on the case design the reductions may not be all that great.

Looks like the new AP tasks are from some 2008 tapes. I wonder if these are tapes that had to much noise before, but now are able to be split with the work they did to the splitter code.

Hmmm... I was to busy at work to check if I has a bunch of pent up transfers, but all of my systems are clear on transfers and have their full set of tasks.
32) Message boards : Number crunching : If you were to start from scratch with a new build... (Message 1496063)
Posted 21 days ago by Profile HAL9000
In my test lab I use ghost images of various OS. Testing with various versions of Windows I didn't find any advantage when using one version over another. Normally I just run Windows 7 x64 on them when the machines are not needed for anything else.

Are you able to test GPU apps with those ghost images? My GPU experience - limited to NVidia cards - suggested that XP is more efficient, because of the simpler driver model.

Other than an old 8500 GT I don't have any other GPU hardware to test.

You can add my ATI host now that it's out of APs again. It was still going up from the last time it ran outta APs. As you can see it had dropped from around 30k to 7k and was still headed down last time. 30/4.3= ~7. That's about what my other ATI cards produce. Over FOUR TIMES LESS CREDIT running ATI MB verses ATI AP.

Yes, I'm leaning at MB giving only 25% of what AP gives on most ATI cards. Since I do not care at all about my RAC, I will continue this, until it levels out. That it should be bad I knew, but not this bad. It seems as if you were totally right about this. Not that I ever really doubted you.

I've run this test a few times. I have much Experience in the matter. At least with Windows, and now Linux, you can gain a few token ATI credits when the APs run out. With my Mac however it's over, nada, zip, nothing for your ATI card when the APs run out...Freefall...

Well, I'll continue, partly because I'm interested in where my particular setup levels out, and partly because I may be crazy :-)

What is this may of which you speak? I'm pretty sure we all know you are a pecan.

why the huge jump in the cricket graph with no AP being sent out??

The answer is in the post just before yours. Looks like a shorty storm. Hope you have your wellies on.

It's just spiked up to 683.09 Mbits/sec

Whatever it is, it's more than shorties - and it isn't AP either. Other speculations would be making old data available to other researchers at other universities, or a local copy of Eric's speech video going viral.....

The jump from 100Mb to 300Mb could have been from shorties, but after looking at the haveland stats for the turn around rate it appears perhaps not.

If my observations have shown me anything I expect the RAC to drop below the average daily credit amount and then slowly come back up to level out. So bottoming out around 6500-7500 before coming back up to over 8000 would not be surprising to me.

It seems that GPU cards are starting to come out at an ever increasing rate. Is it the gamers who need more power faster or Just a marketing gimmic?
Im not complaining, that means the high end cards now we be cheaper when I need to upgrade.

4K UHD displays are starting to make their way to market. Which I guess means they need to crank up the power to give the same frame rates with 4 times the pixels.
Short term they are probably cranking things up, but then will settle back down as time goes on.

Well AP splitting is almost finished so get ready for a steady flow of MB work soon.

Cheers.

Wow. Over 10 hours later and no one is wailing over the APs running out.

Well if we could burn thought the MB faster then more AP would get loaded quicker, yes?

You could run each car in a separate BOINC instance. Then you would have precise control over the configuration of each card.
Unless your goal is to have a single machine with high RAC. Then this would not be your desired option.
