Sometime Saturday or Sunday, we expect to be starting the ESP project on the BOINC server.

We're going to start with some double check work before proceeding to new work. This is to insure that all previous work is correct.

Some interesting facts about the double check:

• One of the things we've learned from examining the data on our BOINC server is that enough computers have computation errors that everything needs to be double checked. On a conjecture project such as ESP, missing just one prime can mean millions of unnecessary CPU hours get spent checking candidates that didn't need to be checked.

• There are 12 k's remaining in the Extended Sierpinski project. We'll be checking those 12 k's.

• We'll also be checking 8 additional k's with known primes between about 1.1M < n < 3.2M. We want to fully check all the candidates with n below the known primes. This is to insure that we've found the minimum prime in each k. This goes a bit beyond proving the conjecture, but has a use in determining the frequency of primes in each n range. This "min-prime" checking will add a day or two to the total double check.

• I expect the entire double check to take 3 to 4 weeks, more or less. It depends on the level of participation.

• Everything below n<500K was manually checked and double checked by us. In many cases, the tests were triple checked or quadruple checked.

• There's about 1700 tests to be done between 500K < n < 1.1M. Tests at that n will only take a minute or two on the fastest computers.

• There are about 97K tests between 1.1M and 2.5M.

• There are about 101K tests between 2.5M and 5M.

• Work on the ESP PRPNet server went to about 5M. Once we get above that, we'll be testing new numbers.

• Most of the double check tasks have a residue, so only one test will be needed on BOINC to confirm the residue. A small percentage of candidates don't have residues and will need to be checked twice.

• It's unlikely we'll find a missing prime, but you don't know for sure until you actually look.

• Special thanks go to Jim, Lennart, Ardo, Lumiukko, and John (yes, that John) for all their computing power doing the initial work on the double check effort!

Not sure if I just missed this, but are you planning on restarting ESP Sieve (as PSP Sieve) at the same time as you start ESP LLR? Or will that be at a later date?

Thank you,

We'll restart the sieve at a later date. We're sieved up to 10M right now. The new sieve effort will sieve from 10M to 50M. PSP and SoB are already sieved to 50M.

That will happen after it's otherwise live and we've been able to test it internally to make sure everything is correct. Making it selectable to the public is the very last step.

Which has now happened. ESP is live, and the double check is in progress.

We're about 2% done with the double check. 62 residues have been shown to be wrong, while 21,658 have been proven correct.

"Work" and "percent" refer to the total computation time required to crunch all the numbers, and takes into account not only the number of tasks, but the size of each task and whether we need to do one or two tests on each number. "Single" is the number of tasks for which we have a residue and only need to do a single test, and "double" is the number of tasks where we don't have a residue and need to do two matching tests.

Of the 8 k's where there are known primes, for 3 of them we've passed the known prime and all the tests for those 3 k's have already been sent out.

EDIT: We found about 10K residues that had not been imported, so the number of double-pass tests has been reduced by almost half. The table above has been updated to reflect this.

None of these.
It should state Extended Sierpinski Problem v6.24

If you want to make sure you get (only) ESP, select it in your account / preferences accordingly.

What is a residue and how is it relevant to the number of tests done? I have some math background but apparently not in this area.

Think of it as a checksum on the calculation. It allows us to verify that the calculation was performed correctly beyond merely checking if the number is prime or composite.

So, there are new units mixed in with double checked? Most of the ones I am getting now require a wingperson.

If you look in the chart in the stats updates, there's a column labeled "double". Those are tasks for which we don't have any residues for whatever reason. We need to do two passes on those tests.

No "new" work will be sent out until every DC task has been sent out.

Almost all of the missing residues reside in the range we're testing now, so we're going to do bunch of them in the next day or two, and then everything after that has a residue.

Remember when the ESP PRPNet server had a disk crash and we lost data? That was at n=2.5M, and that corresponds to the range where the majority of the missing residues are. There's also a few missing residues around n=1.3M, but I don't know what caused that.

Thank you for the explanation. I knew I should have read things better before posting. Although I am sure others were wondering the same thing and so it did answer a question that may have been on a few minds.

Understand that it's possible some of the residues don't match because they were done with a different program. For example, PFGW, if running a PRP test rather than a primality test, produces a different residue than it does when doing the deterministic (-t) primality test, and it's different than LLR's residue.

So different isn't necessarily wrong, but it is different, so we need to run another test.

That being said, as of right now, 70,485 residues have been verified, 408 have turned out to be "wrong" (or at least different), and 102 are currently inconclusive.

Indeed, Jim did a great job with those status pages, don't you agree?

I'm out of town for a few days so I won't be posting any stats for a while. I'll decide what to post when I get back.

Serge Batalov just provided me with 5982 residues from his independent LLR testing of some ESP k's. I checked those against the residues I already had, then applied the result of that against BOINC. Bottom line is that 4339 workunits for k values 91549, 99739, 193997 and 209611 have been removed from this doublecheck. For those candidates, Serge's residue matched what I already had from PRPNet. Of the other residues, some were already out for testing here and some had been sieved out (our sieve was much deeper than Serge's).

Thanks, Serge.

Purely for my own interest, I took the six data points that Michael gave with Wrong (or Mismatched) residues compared to Total Tested, and then calculated the mismatch rate:

+Wrong--Tested--Percent+ | 062 | 021720 | 0.29% | | 408 | 070485 | 0.58% | | 756 | 148381 | 0.51% | | 789 | 154991 | 0.51% | | 813 | 161764 | 0.50% | | 836 | 167041 | 0.50% |

Two immediate things: firstly, my ASCII table-fu is terrible. And secondly, after the initial noise, the error rate is about one in two hundred.

Is that about expected? Worryingly high?

No real opinion on that. We're not even sure if those are errors or if it's merely because a different program was used.

I expect that sometime tomorrow the server will send out the last of the ESP double check tasks and we will start working on new ESP numbers. That's 16 days after we started.

The double check is now 90% complete.

I expect that sometime later today the server will send out the last of the ESP double check tasks and we will start working on new ESP numbers. That's 16 days after we started.

Yesterday we loaded new (i.e., not double check) work into the system. This threw my double-check statistics off by a little bit, in particular the "xx% completed" statistic. If you've been keeping close track of the daily numbers, you may have noticed we seemed to make less progress in the last 24 hours. In fact we did the same amount yesterday as in previous days, but the statistics had this artificial downward jump due to the new work being loaded.

At the rate we've been crunching, the server will likely send out of the last of the double check tasks sometime before the SR5 challenge starts. Of course, lots of people will be switching over to SR5, so ESP crunching will slow down, but we're basically at the end of the double check. We have to wait for the tests to come back, and a few will need to be sent out again for whatever reason, but essentially we're all but done.

The double check went a lot faster than expected, and that's a testament to how dedicated you all are.

Thanks... and onward to the Sovereign Challenge.

All of the double check tasks have been sent out, and we're now sending out new ESP work.

I expect there will still be some DC tasks being recycled and sent out again for the next week or two until they're all completed.

Great job everyone!

The very last workunit in the ESP double check has now been validated.

Final totals:

Verified residues: 184763
Wrong (or not matching) residues: 1150
Candidates with no residue (and thus checked twice by us): 12719
Missing primes discovered: 0
