21) Message boards : Number crunching : How can I get over 500 AstroPulse Tasks at a time as this Host? (Message 1394416)

Post:
I think there is something else going on. When I try to have the server transfer tasks to the GPUs, if I have 100 GPU tasks, it refuses to send more until it drops below 100. Same thing with the CPU tasks. Something going on...


No, he is rescheduling using Freds Rescheduling program, which does not involve getting the server to transfer any tasks from CPU to GPU. It's all done locally on the local computer.

So, the program keeping track of, and reporting 371 tasks, doesn't have any interaction with the server? It would seem if the program keeping track of the number of tasks reported 371, alarm bells would ring. Scratches head...


The way I understand it is that the BOINC servers send the AP tasks to the guys CPU. He then Reschedules those tasks to his GPU. The GPU does its thing and BOINC Manager reports back the finished AP tasks.

The BOINC servers see those tasks come back, IIRC, still marked as if they were issued to the CPU. The server sends more... Rinse - Repeat

All that Freds Rescheduling program does is let YOU choose whether your tasks are crunched on the CPU or GPU. But, as others have said, it does tend to gum up the works.

Wouldn't you know it.

I just installed another GTX 560 in my PC and set it to crunching after I was satasfied with the temps. I checked the webpage 5 hours later to see how it was going.

Hmmm, a few Invalids, I must have something not quite right. Reinstall drivers, adjust cooling scheme.

Then I notice another machine has a couple of Invalids. I checked here and find out it's not just me. What a relief.
24) Message boards : Number crunching : Question about optimized applications (Message 1381082)
Posted 14 Jun 2013 by Profile Tazz
Post:
After reading over this forum for a while, I have heard other people mention that they were using different optimized applications for doing the work units.

So far, I have been using the BOINC manager to do my crunching, and as I am beginning to get more interested in this project I am looking for ways to improve.

Should I be using an optimized application? What are situations where it would be beneficial to do so - is it for everyone? Is there any information about this topic available that I may have missed?

Thank you in advance to anyone who may reply.


The optimized apps will be faster than the stock apps and the new installer makes it easy to install them; but where the stock apps will auto-update when an updated stock app is available the optimized apps will need to be manually updated. By regularly checking these message boards you will know.

BOINC Manager will still be used it's just the programs that do the actual work will be different.

If you decide to go optimized you need some information about your machine(s) first. Download and run CPUz to find out what instruction sets your CPU has (SSE, SSE2, SSE3, SSSE3, AVX ...). I'm not familiar with Intel CPUs so I can't tell what yours is capable of.

Next you need the installer, installer for 32 bit Windows and the installer for 64 bit Windows. Shutdown BOINC before you do the install, the installer will do it for you but I like to do it myself.

Run the installer, after clicking through the obligatory 'Yes's, 'OK's, and 'I Agree's you get to choose what to install. From what I understand about the new installer is that any options that you cannot use will be greyed out so you can't screw too much up. Choose the 'highest' (SSE2 instead of SSE, AVX instead of SSE2 ...) option that you CPU supports.

The next section sets up ATI GPU, you dont have one so don't select anything. Just click 'Next'. In the Nvidia section you can choose to process Astropulse and what version of Multibeam (regular SETI work). The stock app is the same as the Optimised app right now and I see that you've already completed some cuda42 work so choose 'Lunatics_x41zc_win32_cuda42'.

Continue through the rest of the install and there you go. You will know if it's working if you look in the startup messages of BOINC and see "Found app_info.xml; using anonymous platform". Also open the Task Manager and you should see a program running called something like 'AKv8c_B XXXXXXX' depending on what option you installed.

I'm using a Corsair H70(Water Cooling) and My cpu temps while crunching stay at about 45°C, idle is about 29°C to 32°C


I'm cheating a little with mine. My case is OLD with nowhere to mount a radiator, and being the cheapskate I am I made it work. It's always getting air from outside the case and keeping it outside the case.

Probably as good a place as any-

Is there any one around that had been running the older stock or optimised CPU applications and is now running the new optimised application & making use of the AVX support?

Since upgrading from the old optimised application to the current v7 optimised with AVX supprt, my i7 2600 CPU is now running about 5°c hotter.


My AMD 8150 was normally running 24°-25° with the optimised SSE3 app. Now it's getting up to 27°-28° with the AVX app. I'm getting a little worried ;)

P.S. Sorry for the English


Have you enabled SETI@Home v7?

Go to your SETI@Home account page, then click on "SETI@home preferences", then click on "Edit SETI@home preferences". Check the box for SETI@home v7 and save the changes.

Then update the project in BOINC Manager

You may need a cc_config.xml file to tell BOINC to use both graphics cards. Check out the wiki for it.

That is true. I had to make one to use both cards. Here is howto that I followed:

Ahh yes, I did know that but it had slipped to the back of my mind. I just added it.

I just won a second GTX 560 on ebay today, to go with the one I already have so it'll be a couple of weeks before it gets here. Just getting prepared, so-to-speak.

Motherboard: GA-990FXA-UD3
Video card(s): EVGA GTX 560. Same clock speeds, one has 1GB the other 2GB VRAM.

The motherboard manual don't say anything about SLI just Crossfire, but the Gigabyte page says "4 PCI-E 2.0 interfaces for 2way AMD CrossFireX and SLI multi-graphics support"

I've found the setting in the BIOS for what card to use for the display. Nothing about Crossfire or SLI in there.

I'm currently using the 1GB card for my display, when the other one comes I want to use that one. Will it be as simple as keeping the 1GB card in the PCIEX16_1 slot and putting the 2GB card in the PCIEX16_2 slot and telling the BIOS to use PCIEX16_2 for the display? Should I re-install the geforce drivers or will Win7 pick up on that and use the drivers already installed? I remember something about dummy plugs if there's more than one video card, is that still required?

Now, what about SLI? Disabled for S@H right?

To enable SLI I do that in the Nvidia Control Panel. I've read some places that say I don't need a SLI bridge and some that say I do; what's the correct way? I must have put mine somewhere to keep it safe and so I'll be able to find it when I needed it because I can't find it now :(

Any and all input is appreciated.

I have a few more questions:

-I am running an AMD Radeon HD6570. Is there a resource here that will tell me what optimized applications it supports?

- will deleting the app_info.xml result in an update to the V7 stock applications?

- how much performance would I lose staying with stock apps?

- Are AMD and ATI the same thing? In the first page of lunatics 0.4, it shows that AMD users must select SSE3_AMD, but the next page has ATI functions.


I don't have an ATI card so I can only answer a couple, others will chime in. Also, I've never run the stock app for more than a day so I have no idea how much faster the Lunatics apps are, just that they are. :)

Deleting app_info will cause an auto update to v7, it MAY also abandon/error out any current work you are working on.

Download the new optimised installer, it's pretty straight forward. AMD refers to the CPU; SSE, SSE2, ... Are CPU instructions. ATI refers to the video card.

Post:
After a few weeks of worrying about the Validation Inconclusive section when it was added, and after poking around my wingmens task list I came to the conclusion that that section is the list of wingmen with troubled machines processing work. As soon as a 'working' machine sends it's results in mine are OK.

Once in a while I'll get the short end of the stick and get less or no credit for a task, but it don't mean that my box is sending bad results - so far.

Now I start worrying if I see anything other than 0 in the Invalid or Error section.

I wish that the task list had 'Work done by GPU' and 'Work done by CPU' sections.

I got the same errors on one host, but the next messages said it was restarting the tasks. They started from where they left off. Everything seems to be running fine. No mention of downloading files other than workunits.


Let me guess the host you got it on is the one running boinc 7.0.64?


6.10.58 on that one.

There's no SSE3 in the installer it's SSSE3 (triple X!) and AFAIK AMD doesn't have that. We plan to make additional versions available at some point (after we sorted out that stupid upload problem so we can actually host ourselves...).
AVX should be best, if you can run AVX, yes. YMMV - if in doubt run one app and note runtimes at different AR and then run the other app and compare runtimes at similar AR.



Currently there is no SSE3 app.

Due to time constraints, the team decided to focus on SSE2, SSSE3 and AVX development.
The gain from going from SSE2 to SSE3 has been very small on many never architectures, so it was decided to skip SSE3 for know and perhaps include it in a later installer.

So your installer is working as it should.

The AVX ought to be the fastest on hardware that supports it.



Thanks for the quick reply. I guess I didn't count the S's, they all ran together.

Great job guys!!

The install/upgrade went smoothly on three of my four rigs. Actually, the one in question - this one - is running the opti app, just not the correct one.

It's an AMD Phenom 9650. It ran the v6 SSE3 apps, but the SSE3 tic box is greyed out in the installer. Just the SSE2 option is available. CPUz says that it's SSE3 capable too.

Not a big problem but if there's a way to change it I'll do it.

Also, on another machine I can use the AVX app. Is it/should it be faster than SSE3?

Thanks again to EVERYBODY that contributed to the apps and the installer, it's very much appreciated.

The 7200.11 line was supposed to be 'fixed' but, as it turned out, some of them were affected and needed a firmware update too.

You can check your firmware here.

i have a 680 crunching 3 wu at a time and an intel graphics onboard that is currently not doing anything. have set to NNT and waiting for everthing to finish before upgrading. my question is when i upgrade and the new boinc sees the intel graphics and starts to use it will it try to crunch 3 wu at a time on it.


I had an ASUS M3N78-VM motherboard that had on board GeForce 8200 and I was able to crunch wu's on it. The running time was longer than the Phenom 9650 CPU I had in it but it still worked. If I'm not mistaken, CUDA support started on the 8xxx GeForce series. So if you have onboard GeForce 8xxx or later it *should* work.

I don't think that there are any apps compiled for Intel GPUs.

Edit: Didn't know about the OpenCL on Intel. I haven't been keeping up on their stuff.

7.0.33 is the version that has the change with the flops value used for GPU tasks increased by a factor of 10. Since .33 is later than your .31, you'll be affected if you try it on work presently in cache.


Thanks for that. I didn't know if the change in the flops value was what kicked off the .3x series or if it was just added when it was ready for mainstream.
