Ruby 321 for me.

Thanks for all your replies. It is now working, although with xsensors core temperatures appear to be up from 73C to 80C. (Running at 40x 100MHz on a 4770k.)

Again ~10^4000000 thanks!

ps. I noticed that I had missed out a "<" in the app_config.xml file.

Guys, I am on Debian 8 -- not Windows. Where on this do I put app_config.xml?

I have tried ".BOINC" and I have tried "/var/lib/boinc-client/" and "/etc/boinc-client/"

Once I have the file in place, what are the steps to get started with it? (At the moment I am running 4 tasks in parallel.)


Since you have already downloaded some LLR321 tasks, you can search for respective app_name in your client_state.xml file.

(if you setup unknown app_name, BOINC will ignore this settings and should continue using default. In case of doubt, disable BOINC network activity, stop BOINC and do a backup.)

Basically, you can continue using 4 cores per task.
Stop BOINC, place app_config.xml and run BOINC again.
BOINC will grab first task, finish it using 4 cores from check-point then will proceed to another one, etc.



"place app_config.xml" -- where exactly?

Is this correct XML content for app_config.xml for 321?

Have you updated the BIOS? There is a known bug with Skylake.

Like others have said, monitor the heat with some software.

With 8 threads it's much faster than with 64 threads (64 core PC)

./sllr64 -t8 -d -q"64598*5^2318694-1"
Base prime factor(s) taken : 5
Starting N+1 prime test of 64598*5^2318694-1
Using AMD K10 FFT length 512K, Pass1=512, Pass2=1K, 8 threads, a = 3
64598*5^2318694-1 is not prime. RES64: 47DC8FF7EF9583A8. OLD64: 5C3C1DD5662F6EF0 Time : 10211.895 sec.


Presumably it's using one socket ;-) What about 16 threads? That would still be one socket?

I just checked WolframAlpha and these are previously proven primes. I've decided it's better to go for primes than for T5K.


How did you ask Wolfram Alpha to get that answer?

I do not think Wolfram Alpha keeps lists of "ordinary" primes of this kind and size. If I ask isprime(2^9004-59) or isprime(2^9584-59), I get no answer.

Given the probable-primality you found, it is extremely likely these two numbers are prime.

I get an answer from Wolfram. It takes a few seconds. It is doing a PRP test not really a primality test. So there is some remote chance it will be wrong!

You can guess that Thomas or someone else has done sub-mega tests.

Unfortunately, prothsearch.com/riesel2.html seems to be down.
