Thanks a lot.

I am not sure to understand all the concepts under (between memory, CUDA ...), but nothing really to do.

I have tried to use the latest drivers from AMD and depending on version not resolving anything and for the latest dont use the GPU. It is an old card (6 years !).

So i stop Collatz and continue with others projects, and could be back if i change my workstation (not on my roadmap, too many time to configure a new one).

Bye.

All the task at the same moment are at an identical memory address but the olders are not at the same address.

By security i have test (soft) the memorry without problem.

Thanks for your answer

Just completing, now 3 tasks "Collatz Sieve v1.20" have finished with errors after more than 44 hour each of CPU spent.

I will verify if there are bugs on my disks (cross link) but probably not on this configuration.

And the error is an "Out of memory" for a station with 24 Go of memory !

The calculation continues to stop with errors, apparently only those using GPU "Collatz Sieve v1.21 (opencl_amd_gpu)". Now Collatz Sieve v1.20 finish without error. I have check drivers, C++ redistributable version, looking on this forum

Sometime i try new WU, and hope that the problem is resolved, but it continues without any way to solve, and no respons. And so i stop the application for a new time.

Other application using this old GPU worked well, and i don't know why this one stop working.

With this modification

threads=64
lut_size=10
sieve_size=20

it continue to finish with errors

I hope i do what it is expected.

I create this line in the the file "collatz_sieve_1.21_windows_x86_64__opencl_amd_gpu.config"

threads=64
lut_size=10
sieve_size=20

without understanding anything !

Looking myself to error report and i could see :
(unknown error) - exit code -529697949 (0xe06d7363) after a large amount of time spent

It seems to be an OutOfMemory for the CUDA and depending on the project a problem of C++ exception and/or design of the application;

All says itsnt a problem of the PC.
I find something like that in the forum http://boinc.thesonntags.com/collatz/forum_thread.php?id=1331&postid=21505 but not understand all

Does the developper of collatz respond in the forum ?

With the official version of redistributable library, it continues to get error. All this week end from 27 to 29 august, but not alls.

Is somebody could understand the error report ?

Thanks

It is installed and not modified from 2014 (Windows said !).

My version is a bit more recent 10.0.40219 than the Microsoft download center 10.0.30219. And tentative to install failed with a message that a later version is already installed

The only thing i could do is to reinstall after uninstalling. I hope it don't get any effect on another soft needing this version -> I done with the version of official downloadcenter.

Just for understanding (i am surely dummy) : where i could find the information on the redistributable package missing for Collatz and is it so explicit ?

Thank's

At this time near all calculs (80%) are finished with error. I am not looking regular to results but in past my PC was working a lot for this project

I have not change anything in hard or system. I couldn't get new driver for this GPU (impossible for this ATI FirePro V5800 (FireGL V) and Windows 7, probably a bit too old. I have recent boinc client.

Is there an explanation and something to do ?

Thanks
