Does your computer BOINC?

At the moment I'm running BOINC as a service install for the greater security, and that precludes letting BOINC use my graphics card, but if you have a reasonably modern graphics card, and if you don't use a service install, you should try seeing what BOINC will do with your graphics card.

The results will be absolutely stunning. Especially if it is a project that once did CPU work, and you know how long the workunits take on a CPU doing SSE3 calculations.

Moore's Law being what it is, modern graphics cards are more powerful than anything built by Cray Research before Silicone Graphics bought them out. And having your BOINC tasks processed by the equivalent of a Cray supercomputer is pretty amazing.

Your jaw will drop when you see your graphics card knocking off 10-hour workunits in less than a minute, over and over, every minute another 10 hours of work done.


By the way, if anyone thinks I'm at all exaggerating with the Cray comparisons:

Cray XMP:
0.82 gigaflops (real world)
0.94 gigaflops (theoretical)
http://www.top500.org/system/172500

Cray 2:
2.17 gigaflops (real world)
3.90 gigaflops (theoretical)
http://www.top500.org/system/167107

Cray C90:
13.70 gigaflops (real world)
15.24 gigaflops (theoretical)
http://www.top500.org/system/172830

Cray T3D:
100.50 gigaflops (real world)
153.60 gigaflops (theoretical)
http://www.top500.org/system/170942

The T3D was their first system that linked together hundreds of DEC Alpha CPUs.


And now some graphics cards:

ATI Radeon HD 3870
Released: Nov 19, 2007
99.2 gigaflops (double precision)

ATI Radeon HD 4870
Released: Jun 25, 2008
240 gigaflops (double precision)

ATI Radeon HD 5870
Released: Sep 23, 2009
544 gigaflops (double precision)

@tsarstepan,
I've taken over the Mystery Science Theater 3000's [email protected] team which has lain dormant for years.

And I created the Mystery Science Theater 3000's [email protected] team.

New recruits would be appreciated.

If anyone is planning to use BOINC on a new computer, I'd recommend going with the new AMD CPUs that have solder inside to transfer heat away from the circuitry, unless you are comfortable cracking open your CPU and voiding the warranty as per these links:
http://www.hardocp.com/article/2017/02/21/relid_your_intel_cpu_on_cheap_no_delid_tools
http://www.enostech.com/rockit-88-intel-cpu-delid-tool-review/
http://techfrag.com/2016/04/20/rockit-88-delid-tool-is-here-to-delid-your-intel-cpus/
http://www.eteknix.com/rockit-88-intel-cpu-delid-tool/

I have a new i7-7700K that I am not even overclocking, and when it is under a full load doing calculations I can't get its internal temperatures any cooler than 75 degrees Celsius even with a Corsair H100i V2 chugging away at maximum settings.

I figured I'd be safe going with Intel and not delidding since I wasn't going to do any overclocking. I guess not. At the moment I'm only able to run BOINC on my GPU. My shiny new 7700K is just sitting on idle.

I would only recommend going with a new Intel CPU if you are willing to delid it before you use it, even if you have no plans to overclock it.

@oralloy,
I can't remember what my new(ish) laptop at home is powered by. I'll check it out when I get home this afternoon/evening. Though I never overclock any of my computers because I'm not particularly confident enough in that department.

@tsarstepan,
It doesn't matter so much "what it is" as "how hot it is".

Are you familiar with CPUID's utility that shows all the details about a CPU?

They also make a utility called HWMonitor that measures various things like temperatures in your computer.

http://www.cpuid.com/softwares/hwmonitor.html

The pay "pro" version isn't necessary. The free version works just fine.

You will want to look at the internal temperatures for your CPU and GPU.

When a CPU/GPU is doing intense calculations, a temperature of 60 degrees Celsius starts to slowly damage a chip's circuits.

Doing non-stop calculations at a temperature of 70 degrees Celsius will shorten a chip's typical lifespan to two-to-six years.

Doing non-stop calculations at a temperature of 80 degrees Celsius will shorten a chip's typical lifespan to one-to-three years.

Doing non-stop calculations at a temperature of 90 degrees Celsius will shorten a chip's typical lifespan to six-to-twenty months.

Then again, if you plan to upgrade to a new computer after a certain period of time, it might not matter if your current one wears out just after you stop using it.

@oralloy,
I'll get that monitor program tonight. I've been getting some weird video glitching yesterday while watching Youtube for awhile. It doesn't seem my system is overheating but it's good to catch any possible problems while the system is still under warranty.

Thanks for the info! There is one thing, although, which really concerns me - security measures. How are these handled?
