Posted 98 days ago by Profile arkayn
I'm not sure why yet, but the LetsEncrypt script didn't update the SSL certificate as expected. I ran it manually and it worked. If you are still having problems connecting, please let me know.


I'm getting the Transient http error, and an immediate backoff.

On my 1070/960 machine, this seems to work out nicely for both cards.

verbose=1
kernels_per_reduction=48
threads=8
lut_size=17
sleep=1
reduce_cpu=0
sieve_size=28

If I go up more it slows down the 960.

I got the message, and I attached via BOINC Manager.

I think he updated to a secure address which is generating the error.

Hi folks,

I have an invalid task, something I have not seen before:

http://boinc.thesonntags.com/collatz/result.php?resultid=19752441

The stderr output looks OK to me. Any thoughts on what may have caused this ?

Thanks,

Tom


I had 2 more:

http://boinc.thesonntags.com/collatz/result.php?resultid=19802167

Any clues ?

Thanks,

Tom


Have you tried changing over to the OpenCL version, I had a couple of invalids with the CUDA55 version as well. None with the OpenCL version.

Faster on my 2 cards as well.

Gotcha. I thought the update was automated.

Posted 1122 days ago by Profile arkayn
with the right os it's not a problem to run both driver. look at my profile and you can see a 660ti and a hd5850 runs on the same win7...for linux you should google this, because i think it's possible there, too


Unfortunately not, Linux only supports one video driver currently.

Win 7 is the best way to run AMD/NVIDIA together.

Ok but as I am not using my GPU for collatz that leaves all the boxes unchecked?


That is fine as long as you have use CPU selected up above.
11) Message boards : News : Murphy's Law (Message 20066)
Posted 1153 days ago by Profile arkayn
Naturally, on the opening morning of hunting season, the server decided to hang while doing the backups. That left the project in a "down" status. Everything should be back up and running now.


I swear you and Murphy are best friends!!!


Maybe you should just shut the project down for hunting season, might make it easier on you.
12) Message boards : Number crunching : using both nvidia-gpu and intel-gpu (Message 20033)
Posted 1169 days ago by Profile arkayn
I stand corrected, the app info is working almost like expected. The igpu WU is in fact using 1 cpu thread for processing however it still shows up on the Boinc Manager as 0.538.


Have you restarted BOINC since you edited your app_config, BOINC will show the old values until you either get new work units or restart the client.

I looked at the applications and they all seem to be x64. Does this mean that I can't run on my MacPro which I think is a 32 bit architecture.


Your processor is a 64-bit one.

Dear All

My Avast Antivirus programme detecs a virus as follows:

hxxp://boinc.thesonntags.com/collatz/download/mini_collatz_6.04_windows_intelx86__ati14.exe

Infection: Win32:Evo-gen [Susp]

Kindly let me have your feedback.

Regards
Lino


It would be a false positive.

Run the file through this site and it will show up clean.

Avast has been falsely tagging most of the BOINC apps recently, we recommend that you tell your AV software to ignore the BOINC data folder.
15) Message boards : Number crunching : Badges (Message 19599)
Posted 1324 days ago by Profile arkayn
WCG has expanded their badges to cover 100 years of PC crunching time.
I wonder if anyone already has a 100 year badge?


It's not bad to prepare for the future.


20 PCs crunching for 5 years = 100 year's crunching. That wouldn't be that hard to do for people with large farms who crunch a single project.


Oh, I forgot that.


Or even for those with rooms full of pc's, 100 pc's in just one year. And yes there are people that have access to that kind of resource and more, and are crunching.


It is probably determined by seconds crunched, add a 8 core machine with 3 GPUS's crunching multiple units and you can get there fairly fast.

Only 10 days to return work units that are showing 95 days to finish. Work unit 5604643

Looks to me like you will finish in another 9 hours.

Gold, Silver and Bronze Badge minimums are:
thresholds for user badges: 844312.88696495 176265.09555125 11119.552035708
thresholds for team badges: 6061718.8836996 1734115.3718501 71889.900445213

There was a bug in the php (does anyone ever run this stuff before it gets checked in to version control?) which was keeping it from working.


Tell that to Dr. A so he can fix it on SETI as well.
18) Message boards : Number crunching : Where's the top 1% RAC point currently? (Message 18829)
Posted 1409 days ago by Profile arkayn
From manually checking the profiles of the top contributors, it seems to sit at 840k a day. As a result there's only about 4 dozen people with the 1% badge. It doesn't include all users, as I'm at 92nd in RAC, which would put me well inside the top 1%, which suggests it's only on active users or some other qualifier.


I do not think it runs constantly either, from what I have seen on SETI it seems to be a one run and done thing.

Posted 1410 days ago by Profile arkayn


Looks like I should be okay, I am at 26.871% after 36:46:19, so I should finish at around 144 hours.


Finished the first in 136:35:17 and got 936.40 for the work.

The next one is much smaller and will most likely be something like 100 points or so.

My GS3 has been running a task for 14 hours now, and is only 4% complete. If linear, that works out to 350 hours, or 14.6 days. The deadline is only 8 days, so it will be late.

Are the short or long solo tasks being issued to this app/android devices?


You can see the size of the WU in the name. The first number is the starting number for the WU. The second is the how many numbers to check. The third is the number times it was sent to clients.

So, solo_collatz_2370352073947768138095_103079215104_0 will start at 2370352073947768138095 and complete 103079215104 numbers. That, by the way is the smallest size. (The large ones are 8 times that size.)

The percent complete is linear so it looks like your calculations are correct. It makes you appreciate the level of optimization done on the x86 and GPU apps doesn't it? A WU on the Android x86 VM took almost 36 hours compared to 4 hours under 64-bit Windows. It looks like I need to add a couple more smaller sizes to the WUs in order for the Android devices to complete on time.
