21) Questions and Answers : Getting started : no acces (Message 1786596)
Posted 13 days ago by Profile Ageless
You only have access to the Help Desk forums (Questions and Answers) because those don't require you to have a recent average credit (RAC) of more than 1 (one).

The main forums do because they are for active community participants, people who actively help the project out with the calculations. You don't seem to be doing so, as under this account you don't seem to have any computers added with which you do Seti's calculations. It is possible you have more than one account and are using another to do these calculations, but then you have to log in on that other account to be able to post with it in the main forums.

Requiring people to actively work for the project also deters spammers, who else can just post their crap on the forums without much to counter them with. Now, if they want to spam, they have to use these lesser forums, or do some calculations before being able to post in main. But that's too much effort for them, as the end result will be banishment anyway.

...it's a number consisting of mostly zeroes.

All of them after the decimal point.

- Boinc Whetstone is used for claim and is scalar (non-simd) Whetstone

In how far has this got anything to do with the benchmarks BOINC does every so many times, and what if one has these disabled? I set through cc_config.xml not to do benchmarks.
How much will it slow the calculations down?
Is it even possible to do any radio frequency data calculations without use of the FFT algorithm?

But doesn't that affect only CPU tasks? The removal of the SIMD extensions at least?

The it's probably got to do with the removal of something, but I can't decide if that is of part of the credit generating code, or David.

To fix the coarse scaling error, what's the alternative to including an allowance for SIMD vectorisation within creditnew for stock applications ?

[Hint: I know the answer already. and so do you]

I know, I know - it's been given a stupidly restrictive remit by those with a vested interest in maintaining as much of the status quo as they can, and it's done nothing visible, and I suspect nothing substantive, since it was created.

They had a BBQ. Or at least a get-together with food.

29) Questions and Answers : Unix/Linux : Getting Intel Open CL Working on Fedora23 (Message 1785938)
Posted 15 days ago by Profile Ageless
Even if you were able to get the Intel GPU to work -which isn't easy, because as far as I know Intel themselves don't offer OpenCL enabled drivers for Intel GPUs for Linux, so you'd have to work with third party stuff like Beignet- it doesn't matter for this project because there are no stock GPU applications for Intel: https://setiathome.berkeley.edu/apps.php

At the moment only AMD/ATI GPUs are supported.

But that could be overcome by building your own applications. And normally, any OpenCL application should be able to work on any device capable of using OpenCL, so conversion between platforms shouldn't be much trouble. The problem is to get the GPU to be recognized and to have it run correct science.

I haven't seen the CPU temperature go over 55C yet on either system, even under heavy load.

I'm now using Handbrake to convert some movie ISOs into HEVC MKVs, this process uses all 4 cores of my i5 at 100% load. Even with the fan running at 90%, CPU temperatures aren't going above 54C on the hottest core, coolest core is 44C. With the fan at 90% (2155 rpm), I still don't hear it. I do hear it when it's at 100% (2450 rpm).

Room temperature is still 26.5C, but I've now opened a window and cooler outside air -22.1C- is flowing in and over the top of my case.
31) Questions and Answers : Windows : Win7 Open CL - Not using GPU if not logged on (Message 1785852)
Posted 15 days ago by Profile Ageless
If I setup BOINC/SETI on this machine in non-protected mode both GPU's will not do any work until I log onto the machine.

Additionally, this is normal as well. Only services run when no one is logged in, normal programs do not.

As to the why on that GPUs don't do work when BOINC is installed as a service, that's all down to drivers. When BOINC is installed as a service, it runs under a limited privilege account. This account does not have access to the videocard drivers, which run under the user's account. And so BOINC will not be able to read that these drivers are installed, thus is not able to detect any GPU.

BOINC runs the programs also from a sandboxed directory, meaning that the privileged account can only read from, write to and execute programs in this directory, and therefore it and possible programs are not allowed to search specific directories on the system to see if certain drivers are there.

This is a security measure Microsoft thought up, so if it needs to change it's up to MS, not up to BOINC to fix that.

I came across this water cooler on my local kijiji. Any thoughts?

Coolermaster seidon 120m

I'm running with a Coolermaster Seidon 120V V2.0 on two machines here, one an Intel i3-530 that I use as a computer next to my TV, for light gaming and streaming of series/films, the other I have on an Intel i5-2500K on which I do the heavy gaming and run BOINC on.

I haven't seen the CPU temperature go over 55C yet on either system, even under heavy load. But then both of these are living in spacious cases with lots of additional case fans. Perhaps that that matters as well.

The i3's radiator is attached to the back of the computer case; the i5 has the radiator on the top side. Both suck air into the case and thus into the radiator. As that's a weird thing, if you add the fan as it says in the instructions, it's blowing out over the radiator. So then it blows the hot air out of the case over the radiator, which I feel is wrong. So when testing on the i5 at the time, I turned the fan around and went from mid 60s to mid 50s Celsius.

I've been running with these for about a year now (29 May for the i3, 9 July for the i5). Using SpeedFanv4.51 to control the fans in the systems is also very useful. When the system are idle, all fans run at their lowest speed, while when under load and stress, they can go to a max of 70% of total. That's enough to cool things down without making a load of noise.

I'm running BOINC now, crunching Seti Guppi's on my AMD HD 7870 GPU.
Room temperature is 26.5C, CPU temp is 47C on the hottest core, but the GPU isn't going much over 60C with a fan speed of 58%. A slight whine, but not too irritating and certainly not as noisy as when I turn SpeedFan off and everything only knows 100% speeds. The ability to set SpeedFan up so that case fans and even the CPU fan work together to get rid of GPU heat is -for me- precious.

The Microsoft Security Intelligence Report (isn't that a contradictio in terminis, Microsoft, Security and Intelligence in one sentence?) writes that between July 2015 and December 2015 malware infections increased a lot on Windows computers.

Hmmm, wonder how they got that data.

And when done that, set DisableOSUpgrade = 1 in the registry as shown how to do at http://www.ghacks.net/2016/01/08/disableosupgrade-prevents-the-upgrade-to-windows-10/. That way, even with all the pre-Windows 10 updates installed, the installer will never try to install Windows 10 or bother you about it.

This is the method Microsoft tells companies is the way to stop bothering them about Win10 updates. It's very doubtful they'll change it so it'll be ignored, as MS doesn't want to be sued by them for infringement reasons.

Or update to BOINC 7.6.31 which looks for both libOpenCL.so to libOpenCL.so.1 libraries on its own.
Locutus of Borg's PPA has 7.6.31 for different distros, and some Ubuntu versions have it from repository.

Yeah well, the Greenbank tasks don't run that well on any GPU. They're either all so called VLARs (Very Low Angle Range) which run for a long time but are incompatible with running on a GPU (any brand GPU), or they run in seconds flat and therefore don't give much credit. I think 1.35 was the max I had.

So please, don't stare yourself blind on that.

When you had the Nvidia GPU, what did you do to get it to recognize?
Perhaps the same path is needed for AMDs. (Sorry, I'm more of a Windows guy, but apparently all the Linux gurus are busy elsewhere).

I've asked Gianfranco to take a look here.
As for uninstalling BOINC and installing the one from Berkeley, these two aren't compatible. The one from repositories runs under an unprivileged account and installs in various system directories, while BOINC from Berkeley runs under the user account and installs everything in the Home directory.

How many times did you have the error?
If only once, it may just have been a fluke. But if you do not manage to return any work without error it's something to look into.
