Vajolet2 released

[elcabesa]

i just discovered i need to add "-mpopcnt" to the compiler options to let gcc use popcnt instructions

try it when you can and I'll rlaeas a new compile with the four versions

[phenri]

Here is what I get

Code: Select all

sse4.2 popcnt
===========================
Total time (ms) : 39226
Nodes searched  : 29369660
Nodes/second    : 748729
===========================
Total time (ms) : 39911
Nodes searched  : 29369660
Nodes/second    : 735878

sse4.2
===========================
Total time (ms) : 40478
Nodes searched  : 29369660
Nodes/second    : 725570

generic
===========================
Total time (ms) : 55792
Nodes searched  : 29369660
Nodes/second    : 526413

include src, sse4.2, popcnt, generic and avx but not tested.

i just discovered i need to add "-mpopcnt" to the compiler options to let gcc use popcnt instructions

try it when you can and I'll rlaeas a new compile with the four versions

And right for me.
Thanks, always learn.

Hi Marco,

your source code compiles well with g++ 4.7.3 on the mac. Get this bench output

But unfortunately violet crashed in every game. Started from the terminal, violet shows "Buss error: 10" after some seconds and terminates
