Welcome to the Hans Ivar Riesel's 90th Birthday Challenge

The third Challenge of the 2019 Challenge series is a 7 day challenge to celebrate Hans Ivar Riesel's 90th Birthday! The challenge is being offered on the The Riesel Problem (TRP) (LLR) application.

Hans Ivar Riesel (May 28, 1929 in Stockholm – December 21, 2014) was a Swedish mathematician who discovered the 18th known Mersenne prime in 1957, using the computer BESK (Binär Elektronisk SekvensKalkylator, Swedish for "Binary Electronic Sequence Calculator"), this prime is 2^3217-1 and consists of 969 digits. He held the record for the largest known prime from 1957 to 1961, when Alexander Hurwitz discovered a larger one. Riesel also discovered the Riesel numbers as well as developed the Lucas–Lehmer–Riesel test. After having worked at the Swedish Board for Computing Machinery, he was awarded his Ph.D. from Stockholm University in 1969 for his thesis Contributions to numerical number theory, and in the same year joined the Royal Institute of Technology as a senior lecturer and associate professor.

To participate in the Challenge, please select only the The Riesel Problem LLR (TRP) project in your PrimeGrid preferences section. The challenge will begin 24th May 2019 00:00 UTC and end at 31st May 2019 00:00 UTC.

Application builds are available for Linux 32 and 64 bit, Windows 32 and 64 bit and MacIntel. Intel CPUs with AVX capabilities (Sandy Bridge, Ivy Bridge, Haswell, Broadwell, Skylake, Kaby Lake, Coffee Lake) will have a very large advantage, and Intel CPUs with FMA3 (Haswell, Broadwell, Skylake, Kaby Lake, Coffee Lake) will be the fastest.

The latest version of LLR now supports AVX-512, which is significantly faster on CPUs that support it. Requires anonymous platform mechanism. For more info see the thread, LLR 3.8.23 released.

ATTENTION: The primality program LLR is CPU intensive; so, it is vital to have a stable system with good cooling. It does not tolerate "even the slightest of errors." Please see this post for more details on how you can "stress test" your computer. Tasks on one CPU core will take 12 hours on fast/newer computers and 1.5+ days on slower/older computers. If your computer is highly overclocked, please consider "stress testing" it. Sieving is an excellent alternative for computers that are not able to LLR. :)

Highly overclocked Haswell, Broadwell, Skylake, Kaby Lake or Coffee Lake (i.e., Intel Core i7, i5, and i3 -4xxx or better) computers running the application will see fastest times. Note that TRP is running the latest FMA3 version of LLR which takes full advantage of the features of these newer CPUs. It's faster than the previous LLR app and draws more power and produces more heat. If you have a Haswell, Broadwell, Skylake, Kaby Lake or Coffee Lake CPU, especially if it's overclocked or has overclocked memory, and haven't run the new FMA3 LLR before, we strongly suggest running it before the challenge while you are monitoring the temperatures.

Please, please, please make sure your machines are up to the task.

Multi-threading optimisation instructions

Those looking to maximise their computer's performance during this challenge, or when running LLR in general, may find this information useful.

• Your mileage may vary. Before the challenge starts, take some time and experiment and see what works best on your computer.
  
• If you have an Intel CPU with hyperthreading, either turn off the hyperthreading in the BIOS, or set BOINC to use 50% of the processors.
  
  
  • If you're using a GPU for other tasks, it may be beneficial to leave hyperthreading on in the BIOS and instead tell BOINC to use 50% of the CPU's. This will allow one of the hyperthreads to service the GPU.

  
  

• Use LLR's multithreaded mode. It requires a little bit of setup, but it's worth the effort. Follow these steps:
  
  
  • Create a app_config.xml file in the directory C:\ProgramData\BOINC\projects\www.primegrid.com\ (or wherever your BOINC data directory is located). For a quad core CPU, the file should contain the following contents. Change the two occurrences of "4" to the number of actual cores your computer has.
    
    
    <app_config> <app> <name>llrTRP</name> <fraction_done_exact/> </app> <app_version> <app_name>llrTRP</app_name> <cmdline>-t 4</cmdline> <avg_ncpus>4</avg_ncpus> </app_version> </app_config>
    
    
  • After creating the file, click on "Options/Read config files". You should then restart BOINC or reboot.
    
  • The first time BOINC downloads a TRP task, it may act a little strange and download 4 tasks instead of 1. The run times on this first set of tasks may look a bit strange too. This is normal. This will also occur anytime BOINC downloads more than one task at a time. This can be avoided by setting "Use at most [ 1 ] % of the CPUs" before you download TRP tasks. After one task was downloaded, increase the percentage.
    
  • Some people have observed that when using multithreaded LLR, hyperthreading is actually beneficial. We encourage you to experiment and see what works best for you.

NOTE: The countdown clock on the front page uses the host computer time. Therefore, if your computer time is off, so will the countdown clock. For precise timing, use the UTC Time in the data section at the very top, above the countdown clock.

Scoring Information

Scores will be kept for individuals and teams. Only tasks issued AFTER 24th May 2019 00:00 UTC and received BEFORE 31st May 2019 00:00 UTC will be considered for credit. We will be using the same scoring method as we currently use for BOINC credits. A quorum of 2 is NOT needed to award Challenge score - i.e. no double checker. Therefore, each returned result will earn a Challenge score. Please note that if the result is eventually declared invalid, the score will be removed.


At the Conclusion of the Challenge

We kindly ask users "moving on" to ABORT their tasks instead of DETACHING, RESETTING, or PAUSING.

ABORTING tasks allows them to be recycled immediately; thus a much faster "clean up" to the end of an LLR Challenge. DETACHING, RESETTING, and PAUSING tasks causes them to remain in limbo until they EXPIRE. Therefore, we must wait until tasks expire to send them out to be completed.

Please consider either completing what's in the queue or ABORTING them. Thank you. :)

About the Riesel Problem

In 1956, Hans Riesel showed that there are an infinite number of positive odd integer k's such that k*2^n-1 is composite (not prime) for every integer n>=1. These numbers are now called Riesel numbers. He further showed that k=509203 was such one.

It is conjectured that 509203 is the smallest Riesel number. The Riesel problem consists of determining that 509203 is the smallest Riesel number. To show that it is the smallest, a prime of the form k*2^n-1 must be found for each of the positive integer k's less than 509203. As of December 13th, 2017, there remain 49 k's for which no primes have been found. They are as follows:

2293, 9221, 23669, 31859, 38473, 46663, 67117, 74699, 81041, 93839, 97139, 107347, 121889, 129007, 143047, 146561, 161669, 192971, 206039, 206231, 215443, 226153, 234343, 245561, 250027, 315929, 319511, 324011, 325123, 327671, 336839, 342847, 344759, 362609, 363343, 364903, 365159, 368411, 371893, 384539, 386801, 397027, 409753, 444637, 470173, 474491, 477583, 485557, 494743

The Riesel problem is to k*2^n-1 as the Sierpinski problem is to k*2^n+1. There is no equivalent to the 'prime' Sierpinski problem since k=509203, the conjectured smallest Riesel number, is prime.

What is LLR?

The Lucas-Lehmer-Riesel (LLR) test is a primality test for numbers of the form N = k*2^n − 1, with 2^n > k. Also, LLR is a program developed by Jean Penne that can run the LLR-tests. It includes the Proth test to perform +1 tests and PRP to test non base 2 numbers. See also:

Some good news and some bad news.

The good (actually great) news is that we got testing done on the new LLR version that supports AVX512. If you have a brand new state of the art Intel CPU that supports AVX 512, you will see a significant increase in performance.

Now the bad news. Intel pulled an AMD and on the mid and lower range Xeon CPUs included only one AVX512 execution unit per core instead of two, which really clobbers the AVX512 performance. The dual unit CPUs perform great. The single unit Xeons actually perform worse on AVX512 than with FMA3.

You can find the list of single and dual unit AVX-512 CPUs here.

Fortunately, there are not a lot of the single unit Xeons in use at PrimeGrid. That isn't much consolation if yours is one of them, however. At this time, the only remedy is to run the old 3.8.21 version of LLR using app_info.xml/anonymous platform. I'm optimistic that we'll be able to fix this, but that will not happen until after the challenge has ended.

I apologize for any inconvenience this may cause.

How do we create a xml file?

How do we create a xml file?

Once we reach n=10,000,000 we'll have k=342,847 and k=444,637 automatically added back to the search. That'll require an advance of 5.8% from the leading edge from the beginning of the challenge. TRP has been sieved to n=50M and each k has a different number of candidates to test based on their weight. These two k's are the lowest weight of the remaining k's with the least number of candidates for a given range. As long as each k has been sieved to the same level then each remaining candidate has the same chances of finding a prime.

Have a look at the thread Chance of TRP Prime to get a feel for some of the chances in the up coming ranges. Finding a prime for a low weight k is harder in a given range than a higher weight k. If all tests took the same time it wouldn't matter, but as n increases the time to test goes up. So finding a low weight k sooner is more valuable to the chances of solving the overall conjecture, which is not a sure thing.

if we also want to do multithreading on other subprojects, do we write the same thing over and over again or we can only do one subproject at a time?

Normally we do about 800 tasks per day. We're almost at 10x that pace. Keep it up!

No primes yet... or is there? There's been a prime reported, but TRP's are prone to false primes, and that's what it turned out to be. Just a computation error.

Will we find a prime in the remaining four days???

With one day remaining in the challenge, it's time to remind everyone...

At the Conclusion of the Challenge

When the challenge completes, we would prefer users "moving on" to finish those tasks they have downloaded, if not then please ABORT the WU's (and then UPDATE the PrimeGrid project) instead of DETACHING, RESETTING, or PAUSING.

ABORTING WU's allows them to be recycled immediately; thus a much faster "clean up" to the end of a Challenge. DETACHING, RESETTING, and PAUSING WU's causes them to remain in limbo until they EXPIRE. Therefore, we must wait until WU's expire to send them out to be completed. Thank you!

Overall, we did just over ten times the normal daily number of TRP tasks. Well done!!!

The cleanup begins! I expect it to take about 2 to 4 weeks. Feel free to help out by continuing to run TRP tasks if you wish, but understand that except for right after the challenge, there usually are very few challenge tasks available. Mostly, the cleanup consists of waiting for tasks to be completed by the computers to which they were already sent.

Cleanup status:
