Zappa Mexico (8 cpu) vs Top free UCI engine

[Sedat Canbaz]

Arasan in theory supports up to 16 cores (MAX_CPUS=16 in config.h).

But it does not have a very efficient SMP implementation so will not make maximal use of more processors. I haven't tested it with more than four threads active.

I am working on a more efficient threading implementation but am making only slow progress.

Hello Jon,

Currently i canceled Arasan 10 t4 test at SCCT,due to many losses on time (this happens with both wb/uci protocols)

Have you ever tested Arasan 10 using 4 theads ?

BTW,I used Arena 1.99b4 GUI

I have done some (not a lot) testing with 4 threads. But I don't have a quad machine. The best I can do is run it on a dual Xeon (which also has hyperthreading). Do you see time management problems only with 4 threads or in other situations also?

I tried Arasan only with 4 threads,in the next days will try with 2 threads and if the problem still continue then will inform you
