Installed 13.12, rebooted, still get driver lock ups about every 30-60s :(.

Did you do a full removal of the old Cat 13.1 or just install the new one over the top?
You can use

to get all of the old driver bits out of the system.

I would of thought the standard app would of been properly optimised for my old Core 2 Quad (SSE 4.1) by now, & so the optimised app would make no difference, am I wrong?

Whilst I'm at it, the other question is whether my HD 5850 would benefit from an optimised app?

For the stock app they try to make it generic as possible so that that the same exe will run on most systems. So kind of greater compatibility & less optimized.
The highest level extension may not always be the fastest on your machine. So if you want to install the optimized apps you can try each one to find the best run times for your system.

Across the armpit is how I measured for someone in the other thread. If I purchased clothes that fit correctly. I would probably be a medium or large if I bought shirts that fit correctly, but for t-shirts I like to get XL. Then over time they shrink a bit to fit better or are just kind of baggy. Which I like anyway.

I got 2. So I could wear one and then keep the other.

Thanks Hal

That link actually takes you to the top of the thread (making your post hard to find as it's right down the bottom of the page) so for those interested XL is:

Across at the armpit/sleeve seam: 60CM
Top to bottom: 78CM

Now I just need to get a tape measure, and measure my shirts (never had to do it before).

Odd it takes me to the message. There might be a delay while the thread loads.
Do either one of these links work better for you than the other?

The iGPU is fast enough, but the testing I have done with Haswell so far has shown that running it with CPU work about doubles the run time of the CPU tasks.

Will be interesting to see if DX12 (on hardware that can make use of it) makes a difference for crunching. One of the features of DX12 is it is meant to significantly lower CPU usage while providing even better graphic performance. For integrated GPUs where the entire CPU/GPU package has a thermal limit reducing the CPU usage will allow greater iGPU clock speeds.

DX12 CPU/iGPU power usage
Click on the DX11/12 buttons to compare performance & power usage.
In the Demo displayed, DX12 gave a 74% boost in video performance compared to DX11 just from reducing the CPU load, allowing the iGPU to rampup further.[/url]

THe iGPU wasn't really CPU heavy while processing. It is probably just a limitation of the design that uses shared cache between the CPU & GPU cores. With the Bay Trail not having the issue due to a different cache design.

At the bottom of precision x you will see the precision log with 3 displays. If you double click anywhere on it, it will open up a new window with multiple stats to view. You can run the built in GPU on your chip, but from what I've heard it's not worth it if you have GPUs via the PCIe. Using it tends to slow down the dedicated GPUs from what I've read. Most that have dedicated GPUs don't tend to use it. If you search the threads you will find what I talk about. If that's the only GPU you have them it's fine to use it, others I'd suggest you concentrate on the dedicated GPUs. My 2 cents

Thanks. Should have tried that. And your advice about the iGPU along with advice from others is cause enough for me to shy away from any effort there; as I'm told, "Just not worth the effort".

The iGPU is fast enough, but the testing I have done with Haswell so far has shown that running it with CPU work about doubles the run time of the CPU tasks. I have not run "iGPU + PCIe GPU w/o CPU" as a test as of yet.

Now we need to follow the tape (18fe09ag)to see if he stuck again.

Aparently the actual production of 28WU/sec is enought to keep the RTS buffer rissing.

An average of just 25/sec would be good up to 90k/hr. With all the splitters going I expect we will be hitting the limits of the disk array. I'm not sure they can handle much more than 100k/hr, but let's see what happens! We are only running about 85k/hr now.

Oh no I didn't mean to imply that to you. I simply didn't understand.
But still, I have to question; when will the analysis begin? Do we have to take it on faith that someday it will begin. This confuses me. Help!

I have no timetable. But I know it is not on the way back burner.

Meow!

I think it was mentioned in Jan or Feb they had plans to get some of that stuff on track for this year, but the funds/resources never materialized.
I am guessing that it was specific grants or other funding that didn't come through.

The splitters were bumped several times over the week, but 18fe09ag is a particularly difficult problem child.


Was it? I thought no one touched 18fe09ag at all & the only reason it is at 3 is due to weekly maintenance.

Pretty sure it was bumped 2, maybe 3, times prior to the weekly maintenance.

You are right, they kicj the tape several times but only before the manteinance, after no, i report that serveral time and nobody makes nothing. No forgive-me i get an answer, it was: Pacience Juan. That was few days ago and the dam tape still stuck until now at least (just check). So the RTS buffer allready downs from 300k to 104K and the creation rate is in the range of 21/sec not enought.

I believe you are thinking of 23ja09aa. Which was kicked repeatedly until it finally finished. 18fe09ag Became stuck and then claimed a 2nd splitter. However those were released during maintenance & it has been stuck on 3 since then.

In any event we are down to about 10,000 RTS now. Good luck!

Oh, *lol*...

I never looked there for this figure - as when I was setting all those GPUs up, they naturally hadn't a single Result done yet ;)

Maybe that's something that could be included into a future Lunatics reference document.
(I do remember searching hours for "Compute Units" of the GTX 750ti (actually didn't find it), GT610 and GT720M. That's likely why I eventually just used 'high performance defaults should so' on the 750ti ;) )

There doesn't seem to be a universal/fixed Cuda Cores / X = Compute Units formular or rule of thumb. If there is, that would help alot as well.

Look at SMX count.

For ATI it seems you divide shader count by 80.

Wow Gemini has rushed from 7th to 3rd place.

Can Capricornus keep their place at 2nd... Stay tuned to find out!

Sizes available are Youth M and L, Adults S, M, L, XL, XXL, 3XL, 4XL, 5XL and 6XL.


Hmmm, I don't know how "standardised" those sizes are ...

For example, in Australia (which has a different "standard" for shoes, clothes, etc. than the US or Europe in the first place) I can walk into the same shop and buy two XL shirts from two different manufacturers and walk away with one that is too big, and the other being too small, despite both being XL.

Love the idea, and would love to get one, but which one ???

Ps: shirt width (at the armpits) while flat I think is a better measure of shirt size than chest "size" or circumference because some people prefer a more loose fitting shirt than others, but then again different fabrics shrink by different amounts after washing as well (which just adds more uncertainty) ...

That's why I never bought clothes online before. I know most people would buy it to help support the project, and assist with fund raising, but I would prefer a coffee mug to be honest (a 250 mL mug tells me much more than a "medium" sized mug).

Just some feedback, not criticism.

Across the armpit is how I measured for someone in the other thread. If I purchased clothes that fit correctly. I would probably be a medium or large if I bought shirts that fit correctly, but for t-shirts I like to get XL. Then over time they shrink a bit to fit better or are just kind of baggy.

Yep, it would appear that if nothing changes, MB RTS will leave a smoking crater in the ground sometime Monday evening or Tuesday morning...

Might be before that, at the current rate of decline.

I was thinking along similar lines.
As less AP work is in progress, the amount of MB work increases.
MB results returned per hour had been sitting around 60,000 & that kept the Ready-to-send buffer pretty much steady. Once it hit 65,000 then the buffer started shrinking, now's up around 76,000 & it's really starting to fall.

But alas, I've not been granted remote access to the servers. Now wouldn't that be something?

Didn't Matt or Eric tell us once that to have an extra employee full time would be around 100-150k/yr? Then we could pester them constantly!

My original guestimation was for around 19:00 UTC Monday for the RTS to go dry. However the return rate keeps going up at a small but steady rate. Plus there have been a few sudden drops. So if we go dry Sunday night I would not be surprised.

Crunch em if you got em!

Sorry, but i don't know of any profiling application, which runs standalone and has an user interface suitable for laymens. :/


CodeXL for ATi, Nsight for NV.
Still have to find free good profiler for iGPU though.

EDIT: not for laymans perhaps though. But then продвинутые опции comes in play. Perhaps I need to write in own native language instead of english next time, to make it more clear if english "advanced" word not comprehendable :-/

I think instead of "advanced" it is more "developer" option. Unless you are developer, or reading the code like one, you probably do not understand what the option is actually doing.

Нет проблем, исправлю на "для разработчиков"

Yes, exactly!

Personally I like the information.
It is like those that compete in the Olympics under no country. They group together & fly the Olympic flag in the place of a country. In the spirit of fun & competition.


They didn't choose a team to begin with-they obviously didn't want a team. Grouping them onto a team they didn't request is unethical and invalidates the results of the race

You could choose to mentally exclude them from the results?
Has this issue been raised the previous 2 years?
Perhaps request that in the future that those with no team be listed with team name of user?

-tune N Mx My Mz
FFA_FETCH_WG=1,
FFA_COMPARE_WG=2


It is not 100% clear to me but is work group size calculated by Mx * My * Mz or is Mz for another use? It would make sense to me if -tune 1 8 8 8 = WG size 512.
Setting value for N sets the function to use fetch vs compare? This would be more "Try each and see if one is better for your hardware"?

Kind of frustrating that the #1 says "No Team". If someone doesn't want to join a team you don't put them all on a team called "No Team"

I agree...
It's rather misleading that those who wish to freelance get grouped together as a team to compete against those who are organized into a true team.

Thumbs down from the kitties on that one.
