There are 32 participants, include one guest GNU GO.
After 7 swiss round,
1st CGI 7-0
2nd CrazyStone 6-1
3rd Zen 6-1
4th Aya 6-1
5th Gonanza 5-2
6th Ray 5-2
7th DolBaram 5-2
8th darkforest 5-2
CrazyStone lost against Zen.
Zen lost against CGI.
DolBaram lost against Ray and CGI.
darkforest lost against Zen and CrazyStone.
Top 16 programs will play tommorow tournament.
All top 8 prigrams except DolBaram? use DCNN.
Thanks,
Hiroshi Yamashita

Hello Hiroshi,
thanks for the information.
WHo are the peolbe behind CGI Go?
Which hardware is used by the top participants in UEC cup?
Ingo.

I think they are
https://github.com/CGI-LAB
http://www.aigames.nctu.edu.tw/
e.g. NiceGo, Amigo programs in the past.
I'm curious if they are mainly reimplementing the AlphaGo paper or doing
something else.

Hello Ingo,
As far as I know,
CrazyStone used a machine 24 cores, no GPUs.
Aya used a Amazon EC2 g2.8xlarge 16 cores, 4 GPUS.
Gonanza used a mahicne 16 cores with a GTX 980 ti.
Ray used a mahicne with a GPU.
Zen and CrazyStone uses DCNN without GPU.
I'll use 4 g2.8xlarge by root parallelization.
g2.8xlarge has 16 cores, but I use only 8 cores.
GPUs are slow, so creating node is not enough.
Too many playouts looks harm for tree result.
16 threads is weaker than 8 threads by my 1sec/move test.
Thanks,
Hiroshi Yamashita

The current version in UEC is CGI 2.0 (or DeepCGI) as described in this page (also including the contributors).
The main contribution for Amigo (nothing to do with nicego) is to design a general MCTS framework that many game programs can directly use.
CGI 2.0 is still based on the framework.

We developed DCNN from Dec 2015. That means that we have not read AlphaGo’s paper at that time yet.
But, we are still inspired by their paper.
The hardware used for UEC is 4 GPUs + 40 threads.
Best Regards,
Ti-Rong Wu

(Thanks Shinoda-san).
Holmes got Originality award. Holmes does both Policy Network and playout
on 8 GPUs. Playouts are done by 256 mini-batches. 256 playouts are
executed simultaneously.
