MP tablebase generator

Post by Omega-three »

Does anyone know if there is a MP version of the tablebase generator available and if so where it can be downloaded ?

Thanks

I guess not, and why would you want one? That generator is not CPU bound, is it? It is all disk I/O.

Generating the Tablebase elements do rquire a cpu power....it's not all disk I/O,hence the logical question of the poster....

Actualy I think it is more CPU bound than you seem to think. My hard drive is hardly being used, whereas one of my processors is running at 100% It would be nice for the other three to help out and speed up the process.

I am surprised that a skilled programmer like H.G.Muller is not aware of this fact....

I wonder if you are talking about 5 pc and he may be talking about 6 pc tablebases.

In my own 5-pc generator, when I use two cpus, the time for generation goes down to almost half. The whole calculation is done in Memory (less than 2 Gb needed).

If I develop a 6-pc generator the story will be totally different I guess.

I was talking about 5 pieces of course....I am not aware of a 6 pieces generator yet....

Since 5 men sets are complete in almost every format and not terribly huge, it is only the 6 man generators that are important now (unless someone comes up with an even better format).

My quad has 4 Gb memory, but task manager says newTBGen.exe is using 575,808 k at 25% cpu wuth 74% system idle.

I guess you have a 4 CPU system and so 3 CPUs are idle.
