. . Hiya QBit,

. . Well maintenance is over for another week. One thing though, you might get better results if you increase your unroll from 2 to 4 because the GTX750s have 4 compute units. You may be very pleasantly surprised.

Hi and thx for reminding me!
I was sure I changed unroll to 4 but you are right, it's still at 2. Maybe I forgot to save or clicked the wrong button. Anyway, I just set it to 4.

My RAC is still raising too.
Started on 14th dec at 3100cr/day with my i3-2100T now with the 750ti is runs 6800cr/day (reduced to 18h daily)

OK, something's still strange here.

This morning I (once again) changed unroll to 4 but still all results showed unroll 2.
So I restarted the computer and checked app info. It said unroll 4. So I started BOINC and each wu ran for 1-2 seconds and then went into "ready to start" mode. I lost WIFI, the PC became unresponsive. I stopped BOINC and tried to shut the machine down but even that wouldn't work. So I used the power button and after that the PC didn't even boot up. Next I took the machine completly of power, waited 2 minutes and powerd it up again. Now it's running, I changed unroll back to 2 and everything's fine again.
Maybe my VRAM is too low to run unroll 4? Any suggestions/thoughts?

I tried unroll 3 on mine and it still had just over 1024 used on the GPU running the screen. I don't think you're going to get over unroll 2 to work on that 1GB card. What does it say in nVidia Settings? If you haven't found it yet go to the top of the Dock to Search and enter n. That will list nVidia Settings, after it's running right click it in the Dock and select Lock to launcher. The unroll is for the VLARs, it doesn't affect the Arecibo tasks much.

. . How much system Ram do you have? The swap files get huge with this app.

[edit] . . I didn't look at your set up, I had presumed the 750 had 2GB as that seems to be the case most of the time :( ... my bad.

@TBar: Will check when I'm back home

@Stephen: RAM is 3GB


BTW: Which program do you guys use to check temps and RAM/VRAM? I use psensor atm, nice for temps but doesn't show RAM

For the GPU use nVidia Settings. For the rest I use GKrellM. GKrell should already be installed, but, it appears you used a different Install image than I used. Or, the installer chose a different Kernel for your machine. Yours is showing Kernel 3.16.0-33, I got 4.4.0 from the 14.04.5 image. Go to the Search again and enter GK, if it's installed it should list it. To configure it right click on the edge of the window and select Configuration/Builtins/Sensors/Temperatures. The nVidia plugin should already be installed, just click the boxes and arrange them the way you want them displayed. Of course, the more you display, the more vRam will be used. You could also just use top in the Terminal to show loads.

Yeah, mine is 14.04.2, I didn't want Unity so I looked for 14.04 with the Mate Desktop which looked really nice on the Mint Distro which I tried before I went back to Ubuntu. Should be less resource hungry also then the Unity version.

I think I stick with unroll 2 now and see how it works. From what I can say so far it still seems to be faster then openCL, especially on non-Guppies.

CPU load is low, even lower then on openCL with use_sleep. GPU gets a bit hotter (~4-5 degrees) but is still on the cooler side (current max is 56C/133F)

I just saw this while checking my results:

http://setiathome.berkeley.edu/workunit.php?wuid=2368107861

Since this is a new user running stock I suppose he's running just one task a time. I know this app is tuned especially for those shorties, but can it really be almost 3 times faster then the openCL app?

*edit* Saw somebody running a Cuda 8 app by petri33. Has anybody heard of or maybe even tested this? Looks like there's a lot of development here at linux. Nice!

. . Hi Qbit,

Since I've stuck a 1050ti in my Mac Pro, though OSX has yet to receive a compatible Web driver, will probably be dualbooting that host into Ubuntu as well (once I get a chance to get rEFInd working as a boot manager anyway). Should mean the resources to have the 3 main platforms in sync (more or less), at least once the Linux Kernels settle down a bit, and nV get something happening for Pascal on Sierra (fingers crossed).

It would have been nice if VirtualBox had implemented PCIe passthrough with OSX, but they haven't. Fortunately that's supposedly working in Linux, Which I'll try out after one or the other Linux is up and running natively on it as host. so options for the development automation seem a fraction closer, though still some hurdles to jump.

. . Hi Jason,

. . But is anyone working on a port to Windows??

. . I hope so ...

Stephen

No Porting required, It's been running on mine for a long time. The problem is a serious design flaw in the unroll, that with Windows systems dominating would trash the whole project [i.e. not an option]. Having verified the problem is in fact in the unroll (With TBar's assistance) Instead I am preparing to fix the unroll problem.

This will become less about this/that platform or build, and more about whether or not the app is 'good enough' , which for the moment, it isn't.

. . So I can hope that when(if) the unroll problem is sorted out, there could be a Cuda60 Special app option in a future Beta release of Lunatics?

. . Always keen.

Could either happen that way, or standalone/separate compatible installer. The main goal though is bringing the 3 platforms into line as close as possible, and figuring out eventual stock integration. There are still some complications to figure out, mainly Boinc limitations that require the app be compatible with all Cuda enabled GPUs, however most of those complications don't prevent third party distribution. Only the validation and other more minor functional issues slow that down.

OK, got Ubuntu 14.04 and Nvidia 367.57 working on stock for my new i7 for a 980 and 1070

Now, the list continues, first how to chmod the BOINC dir so I can get rights to edit files? Damn admin doesn't even have rights :(

Then I can play with the settings for peti's code.
