Sorry, read to fast. Re-Reading and noticed : "over the next week or two" :)

Thank You

Dear Slicker,

Thank you for the update.

It's a very good idea ! :)

Do you know when the large_collatz will be released, so we can update the .config &/or app_config files accordingly ?

Thank You

Kind Regards

It seems relatively easy to make the top 5% level and gain the silver profile badge, but where does the top 1% RAC level lie currently?


Dear Spear,

FYI Only, and sorry for the delay ;)

Just received the 1% RAC badge : my current RAC = 1,117,400.66

Kind Regards,

Posted 1383 days ago by Profile [AF>Amis des Lapins] Phil1966
Dear Slicker,

I would like to thank you.

Please accept my appologies for my rough reactions when the new apps were launched.

I never thought it would be possible, but thanks to your .config idea and developpment, I am now able to crunch optimally on Collatz (CUDA "only" - my choice) with my GTXs.

I keep trying to convince my teammates owning GTXs to try + launched a specific topic in our forum ;)

The benefit is nearly 100 %

Thank You

Kind Regards

Philippe

6) Message boards : News : CUDA vs nVidia OpenCL User Poll (Message 18605)
Posted 1430 days ago by Profile [AF>Amis des Lapins] Phil1966
Source of the below info : PrimeGrid Preferences :

CUDA is usually faster on pre-Kepler GPUs (GTX 5xx and older).
OpenCL is usually faster on Kepler GPUs (GTX 6xx and newer). Use whichever is faster.

=> Possible to choose between OpenCl and CUDA + adapt the "block size"
This can be used to vary the kernel size within GeneferCUDA

If possible, this would be the ideal solution.

Every cruncher will be able to try CUDA and OpenCL for nVidia and use whichever is faster / optimal.

If not possible to implement, than solution A.

Again, Thank You Very Much, and please accept my appologies for this "second vote".

Posted 1433 days ago by Profile [AF>Amis des Lapins] Phil1966

I'm working on a CUDA app with the exact same additional validation and it uses 0.1% CPUs so the issue is definitely with the OpenCL drivers. It has been an issue since OpenCL 1.0. Unfortunately, all the vendors have decided that since the OpenCL spec does't require kernels to run asynchronously they don't have to. Quite frankly, nVidia doesn't really care since they "own" the GPU crunching market with CUDA and AMD seems more interested in gaming support than crunching support. Intel is a new player so maybe they will take the lead and produce decent drivers.


Dear Slicker,

I would like to thank you for this good news and for all the improvements you have developped and implemented.

Kind Regards,

Philippe

Thank You Slicker.

Everyone will appreciate your message in its own way.

GoodBye collatz.

Hello,

I am sorry to insist, but this is really the opposite of an improvement, and against "BOINC's philosophy" if each cruncher must start making complicated/perplexing tests and adjustments to try to make the best use of their hardware.

These comments are recurring even between highly motivated and dedicated crunchers, including some from Alliance Francophone.

Both ATI/nVidia users.

I am happy to have the possibility to use app_config.xml files.

But when it comes to .config files ... :/

Not many crunchers know how to manage/configure them ...

I understand, as other crunchers, that you all do your best to have this project running very well.

I tried, using a .config, but I am not sure I will continue to crunch on Collatz if it remains so difficult to configure.

Thank You

Kind Regards

Philippe



Option 1: I can make the app use defaults that work on the newest and most expensive GPUs. For users with older, slower GPUs, the application will crash. They will be told to spend $600 on a new GPU if they want to participate in this project.

Option 2: I can make the app use defaults that will work on ALL GPUs. The screen response may be poor for those with older GPUs, but it will work. Those with faster GPUs have the option to alter the config settings in order to get the most out of their GPUs.

I chose option 2. if you have another option that you consider better and can explain how to implement it that will still allow people to optimize it as well, please let me know.


Dear Slicker,

Thank you for your quick respons.

a) I am not the onlyone to complain about the actual situation. One should not kill the messenger.
You will see or read that VERY EXPERIENCED crunchers are giving up ...
b) $ 600 is exagerated. Here in Europe yes, GPU's are very expensive.
At least 30 % more expensive than in the US. By the way, this is exactly what you did : nVidia crunchers need to go for an ATI if they want to continue crunching optimally.
c) I don't know how the other projects are choosing to code their app. Nevertherless, usually with a simple app_config.xml or app_info file you can solve almost all "problems".
d) I am only a small cruncher who invested into hardware in order to enjoy distributed computing, together with a team. My main objective is to crunch and have fun.
Not to test my hardware in order to understand how it will crunch best on each project.
BOINC should remain a "user friendly environment" ...
e) I am sure you will find an idea that suits all GPU crunchers.(My only actual point of comparison is PrimeGrid's options/choices system)
You're the specialist, I am not.

Finally, thank you for the credits you sent to crunchers who lost their WU's.
I am sure not all other projects would have done this.

Reading your post, I understand it becomes at little complicated to configure BOINC in order to optimize your GPU's "time" ....
Have 2*GTX770 + 1 GTX660Ti and I have no idea what to do with the cc_config info.
The only think I realized is that the crunching time per WU increased a lot,
as well as the CPU time per WU .... (need 1 CPU per WU i/o 0.25 ...)

Nevertherless, thank you for the credits.

Kind Regards

Maybe it is attempting to decode another corrupted WU.
Corrupt WU should be prosecuted and put in jail where they belong!!

Hello !

Just discovered that I have some solo_collatz waiting for validation.

Is this normal as they usually are "auto-validated" ?

Thank You and Kind Regards,
