Perft(14) Weekly Status Reports for 2015

sje · Post by **sje** » Tue Mar 03, 2015 11:26 am

Thank you for your continued work.

It appears your machine had a memory error with wu7.476:

gail&#58;zipunits sje$ pwd
/Users/sje/Dropbox/Public/Perft14/zipunits
gail&#58;zipunits sje$ gzcat wu7.476 | grep r1bqkbnr/pppppp1p/8/n2P2p1/8/4B1P1/PPP1PP1P/RN1QKBNR
r1bqkbnr/pppppp1p/8/n2P2p1/8/4B1P1/PPP1PP1P/RN1QKBNR b KQkq - 0 4 24

Note that '2' = 00110010, 'r' = 01110010, a single bit difference.

Would it be feasible to extend your program's signature length to 128 bits? I suspect that using 64 bit signatures guarantees at least one false positive given the total number of calculations.

I've uploaded your latest results to my Dropbox account, so there's an online backup in case Google goes out of business.

Also, two updated text files:

https://dl.dropboxusercontent.com/u/316 ... turesAnkan
https://dl.dropboxusercontent.com/u/316 ... rgestAnkan

The largest perft(7) result in your calculations so far comes from wu7.458:
[d]r1b1kbnr/pppp1ppp/2n1p3/6q1/6Q1/2NBP3/PPPP1PPP/R1B1K1NR b KQkq - 4 4[/d]
The above has a perft(7) subtotal of 262,332,913,773.

Also, all of your result files pass my simple line count, token count checks.

At this rate you'll need 6 and a half more years, Steven ! Oo

Have you considered designing a BOINC project based on Symbolic ?

sje · Post by **sje** » Mon Mar 09, 2015 5:32 pm

Look again at the last line in each recent report; e.g.,

Code: Select all

Project completion&#58; 49.53%

However, confirmation may take several years if there are no new resources brought online.

Running a full BOINC project takes more resources than I have or care to administer.

Production units (400): 400-799

Total uncompleted work units (478): 068 082 086-087 090-399 800-963
Project completion: 50.47%

--------

In the past week the combination of the 87 work units completed by Symbolic (using 128 bit signatures) and the 400 work units completed by Ankan's program (using 64 bit signatures) has passed the halfway point of the project's total work requirements. However, this does not include independent verification which has been done only for seven work units, less than one percent of the total.

--------

Each week, I update the text file at https://dl.dropboxusercontent.com/u/316 ... 14/Largest which contains a list of positions and their perft (7) subtotals; each position is the one with the largest subtotal of the corresponding work unit as determined by Symbolic. These can be used by program authors for verification and speed tests. The positions are quite varied, and their subtrees contain many special move instances.

An example, from work unit 080:

[d]rnbqkbnr/pBp2ppp/8/4p3/3Pp3/8/PPP2PPP/RNBQK1NR b KQkq d3 0 4[/d]
Which has a perft(7) subtotal of 120,073,988,416.
