Winboard Forum

I am testing all Nalimov TB capable programs I can find for using 5 pieces and 6 pieces. On my site I have lots tested already, I am only looking obviously for ones I missed. I wanted to make the list as comprehensive as possible.

Thanks.

Hello Vegan,

It would help if you posted the ones you had looked at already instead of seeming to be directing traffic to your site. I am sure that is not your intention but it is one inefernce that could be drawn from your post which lacks the requisite information to assist you in your quest.

I suggest that you visit WBEC. You can find vast amounts of information on any engine including whether or not it uses tablebases.

I hope this helps.

Later.

Already cleaned his site out and a few others too. List is pretty long and in HTML table and from experience generally I am averse to posting tables due to blocking of HTM by many operators. I just point to the web-site and this way the format will be clean, <table> <td> </td> </table>

The focus on my effort is strictly on Nalimov tablebases, nothing else (has to work generally though).

After all the work involved in making tablebases, I use them, lots of people do, so hence the list.

Lots of people have seen the list, so says Google Analytics suggesting tablebases are seen in an increasingly positive light.

With the new 1.5 TB disks from Seagate etc. a single disk can now hold 6 pieces and can be taken to clubs and tournaments etc easy.

Sorry, Vegan, your way of testing is not correct. According to your website: Failure to respond causing engine restart is deemed fail as is excessive memory usage.

Memory usage is limited by the tablebase cache memory you set, and is not relevant to whether an engine is capable of tablebase access.

With six men bases, engines take a long time to check and register the available tablebases. This causes Arena to restart in engine matches, but there is no problem if you start only a single engine. Hence you have actually listed engines which are really tablebase capable as failures. And vice versa.

For example, you say that Glaurung 2.1 is capable of 6 pieces, while Spike 1.2 is considered fail!

Well if the program does not work, it is deemed fail. I got lots of engines that do work fine, lots of them. I cannot tell easily of a given engine, I am more interested if it runs than using tablebases. There will always be errors and ommisssions, such is the nature of the beast.

The main issue, if the engine does not respond of commands, Arena will shut the engine down, reload it and start over. Ad nauseum.

Keep in mind my platform may be different than yours. The machine is described and posted off the list.

That is fail, as for memory, UCI engines have a specified cache setting. With the new Winboard engines I have, I set the ini file the same.

I have become averse to manual configurations and was jonseing for some improvements to the WB protocol.

You seem not to understand and from the text above I deduce that you
not really know what you test or want to test at all.
I repeat Danish, Glaurung simply does not and will never use Nalimov
TBS at all. Your tests have a big problem, when they say Glaurung 2.1
passed the tests for 5 and 6 men TBS.

I say it again. I think your posts are just out of commercial interest,
because you want to sell your TBS offers from your site which range
from 30$ to 229$ and even 250.000$ for a future 7men set

I looked at the source code to see that EGTB.CPP is not in use and is not renamed or embedded. Page has been updated.

This is the reason I banned him from the EGTB forum. He kept posting links to his site after being told twice not to do so. This guy is clueless, aggressive and greedy. I seriously doubt usefulness of his contribution to this forum.

Thanks Kirill for the information.

He got warned once here. Let's give him a very last chance to learn the rules.
