Yahoo! News Computer course for shogi fans watching "What is the GPU you often hear these days?" (2)

At Matsumoto , we will continue to invite Mr. Tatsuya Sugimura, the developer of "Water Takumi" as a lecturer, and Akira Watanabe as a guest. The second theme is "What is the GPU you often hear these days?"

Sugimura This is also a difficult question (laughs)

Watanabe Of course, I don't know (laughs)

Matsumoto It was just right. I don't know either (laughs). I think many shogi fans don't even know.

Sugimura GPU is a Graphics Processing Unit, which is a part mainly for drawing 3D graphics.

Matsumoto Yes. My rough knowledge is that the parts that people who play games in earnest place importance on. Are graphic boards (Gravo) and GPU almost synonymous?

Sugimura Almost synonymous. GPU is attached to a part of the grab.

Matsumoto I see.

Sugimura It is often said that the CPU is a college student. There are many elementary school students in GPU.

What is Matsumoto ?

With Sugimura GPU, the number of cores may exceed 10,000 cores.

Matsumoto Well, 10,000? With a CPU, 64 cores is the best class.

Matsumoto By the way, a Go player tweeted that he was happy that the Bitcoin he bought before went up.

I envy Sugimura .

Matsumoto I think most people buy and sell virtual currencies for speculative purposes. It can be gained or lost by going up and down. Do you feel that mining can only win?

Sugimura There is a balance with the parts price and electricity bill.

Matsumoto Of course, there is a break-even point somewhere.

Since it is Sugimura , the price of parts goes up and down according to the value of virtual currency. It seems like that.

Matsumoto : It's interesting that the shogi world is influenced by such movements in the world and the gold rush of the new era (laughs). Computer shogi developers are excellent, so can't you make a lot of money?

Sugimura : To be honest, computer shogi is not profitable at all (laughs)

Matsumoto That's a point to emphasize! !! !! (Smile)

Sugimura , so it's better to use the GPU used for development for mining. It's higher than 0, so it's definitely profitable (laughs)

Matsumoto I have a deep understanding. It's also a story of why everyone is developing shogi software that is far from profitable (laughs).

Sugimura : It seems to be different depending on the person ...

Matsumoto haha. Motivation is different for each person.

Sugimura I have the image of raising a racehorse in a game.

Matsumoto This is a master's specialty.

Sugimura : I'm glad if you devise and become stronger!

Watanabe : It seems to be a lot more difficult than the horse racing game (laughs).

Sugimura : Basically, you don't want to make money from games. Rather the payer.

If you've found a great #domain, but it's already registered, then you'll want to reach out to the owner to see if… https://t.co/h7H5cP1Ygh

It's Matsumoto stoic.

Sugimura : No, Yane-san (the developer of "Yaneura-Ou") has provided various services. I'm playing a game like the Derby Stallion provided. I also feel like that.

Matsumoto I see.

Sugimura It's fun to develop from scratch by yourself!

The person who developed Matsumoto Davista is from Waseda University Shogi Club.

Mr. Hiroyuki Sonobe ( Sonobe Hiroyuki), isn't it? When I met him in curling, I heard that he also likes shogi.

Matsumoto Was that so? Does Mr. Sugimura like horse racing?

I like Sugimura . I watch the Japan Racing Association every week.

Watanabe Was that so!

Sugimura : No, I don't know much about it (laughs)

Watanabe When Corona is over, let's go.

Sugimura Is that true! I'm happy! The current office is close to Nakayama Racecourse. That is one of the advantages.

Watanabe Chiba, isn't it?

Sugimura It is a distance that can be reached by bicycle

Mr. Sugimura Matsumoto belongs to the Motoyawata Chaoyang Law Office in Ichikawa City, Chiba Prefecture.

I heard that unlike Shogi Matsumoto , Go software is still inferior to the top class in the human world. So I was surprised because it was too abrupt.

Sugimura Go has too many legal moves, and it is difficult to make a deep search with conventional search methods. Moreover, it takes a long time to win. I think it's extremely difficult to connect the final battle with the early evaluation.

Matsumoto : Roughly speaking, the DL system had an excellent view of the big picture, and it matched Go.

Sugimura I think so. I've heard that Go AI also makes mistakes in the life and death of long stones. It's similar to the DL system of shogi.

Wasn't it like that was the only station that Matsumoto AlphaGo lost?

Sugimura Ah, maybe that was the case.

Matsumoto : Please ask someone who is familiar with Go about that (laughs).

Sugimura That's right (laughs)

It seems that Go players in Matsumoto generally use AWS. Can you tell us what kind of tendency this is due to?

Watanabe That will be the next time (laughs)

Matsumoto (laughs)

Watanabe One day, one study. I can't remember (laughs)

Matsumoto : Next time, I would like to ask "What is AWS?" Thank you very much.

Sugimura Thank you!

Watanabe I learned a lot.
