沒有沒有沒有沒有沒有沒有沒有。

By the way, this is going to be an audience participation portion of the day.

對了，今天這部分會是觀眾互動時間喔。

So I'm going to ask things and you're going to laugh.

所以我會問問題，然後大家要笑。

I am the chair of the Ultra Ethernet Consortium, and

我是 Ultra Ethernet Consortium 的主席，

I think I may have the wrong slides up here, but we'll go make it through.

我想我可能放錯投影片了，但我們還是會繼續。

But my colleague Uri and I did a presentation yesterday on the Ultra Ethernet, and

不過我跟我的同事 Uri 昨天做了一個關於 Ultra Ethernet 的簡報，

I'm going to be talking to you a little bit about today.

我的意思是，它出現在每一個主題演講裡。

So have you gotten stickers for Ultra Ethernet?

所以你有拿到 Ultra Ethernet 的貼紙嗎？

我本來就不是那種會貼貼紙的人，對吧？

If I had a sticker on my laptop for every time someone offered me a sticker, I'd have a 10-pound laptop.

如果我筆記型電腦上的貼紙，是代表有人送我貼紙的次數，那我的筆記型電腦會重到十磅。

And it's a Mac, so it's already 9 pounds.

而且它又是 Mac，本來就已經九磅了。

So what we're going to be talking about today is an introduction of the Ultra Ethernet Consortium, and

所以我們今天要講的，就是介紹一下 Ultra Ethernet Consortium，

we're going to talk a little bit about why we're doing what we're doing and what we're doing what we're doing.

我們會稍微聊一下為什麼我們要這麼做，以及我們到底在做什麼。

So if you've already been familiar with this, you've heard them talk about Ultra Ethernet, the UEC Consortium, and

所以如果你已經對這個有點熟悉的話，你可能聽過他們講 Ultra Ethernet，還有 UEC Consortium，

然後它也出現在每一個主題演講裡。

It's a big deal for a lot of different companies.

這對很多不同的公司來說，都是一件大事。

As a matter of fact, there's more than 100 different companies.

事實上，這裡面有超過一百家不同的公司。

As the fastest-growing organization in the Linux Foundation history, we've gone from 10 companies to 100 companies in less than a year.

作為 Linux Foundation 歷史上成長最快的組織，我們在不到一年的時間內，從 10 家公司成長到 100 家。

We have a lot of different companies who are looking to try to provide an Ethernet-based open ecosystem for AI and HPC workloads.

我們有很多不同的公司，他們正試圖為 AI 和 HPC 工作負載，提供一個基於乙太網路的開放生態系統。

That sounds like a lot of marketing garbage.

But in reality he's not even saying, "Yep.

Yes, it does." Sounds like marketing garbage.

是的，確實是。」聽起來都像行銷術語。

所以讓我來解釋一下我的意思。

One of the things that we like about Ethernet is the fact that it is incredibly flexible.

我們喜歡乙太網路的一點是，它非常、非常靈活。

It is a great general-purpose network, right?

它是一個很棒的通用網路，對吧？

It does an awful lot of things for a lot of different types of workloads.

它能處理各種不同工作負載的各種事情。

You can do a lot of different types of things with Ethernet.

你可以用乙太網路做很多不同的事情。

The problem is that it's so generalized that if you have a specific workload, making sure that each and every one of those layers is tuned is something of a problem, right?

問題是它太通用了，所以如果你有一個特定的工作負載，要確保每一層都經過調校，這有點麻煩，對吧？

If you want to get the physical layer to connect to the link layer, if you want to get the link knee bone connects to the hip bone, right?

如果你想讓 physical layer 連接到 link layer，如果你想讓膝蓋骨接到髖骨，對吧？

If you want to do that, it actually takes quite a bit of work.

如果你想做到這點，其實需要花不少功夫。

And so what we at the Ultra Ethernet Consortium are trying to do is make sure that that synchronization that goes across all of the different layers is tuned to a particular workload.

所以我們 Ultra Ethernet Consortium 正在努力確保，跨越所有不同層級的同步，都能針對特定工作負載進行調校。

So we have taken the standard Ethernet from the physical layer up into the transport layer and above, and

我們採用了標準乙太網路，從 physical layer 一直到 transport layer 以上，

we've made some tweaks up and down the stack to be able to handle different types of workloads, including AI and HPC.

並在堆疊的上下進行了一些調整，以便處理包括 AI 和 HPC 在內的不同類型工作負載。

Now, AI and HPC have some similarities, but they're not 100% completely the same.

現在，AI 和 HPC 有些相似之處，但並非 100% 完全相同。

And when you start to dig deep into the way these workloads actually function, you start to realize that you need to have different types of approaches to having reliability, orderability, flexibility, multipathing, and

當你開始深入瞭解這些工作負載的實際運作方式時，你會發現你需要有不同類型的策略來處理可靠性、可排序性、彈性、多重路徑，以及

So we need to be able to tweak these things up and down the stack.

所以我們需要能夠在堆疊的上下調整這些部分。

So that's what we're doing at Ultra Ethernet.

這就是我們在 Ultra Ethernet 所做的事情。

At the same time, you want to make sure that it actually works up and down the stack.

同時，你也會想確保它在堆疊的上下都能正常運作。

So we created four additional workgroups that are designed to get the checks and balances and the accountability for this.

所以我們成立了四個額外的技術工作組，來確保這些有檢查與平衡機制，並且有責任歸屬。

And we've got compliance, testing, performance, debug, storage, management to make sure that all of these different horizontal layers are actually working in concert.

我們有合規、測試、效能、除錯、儲存、管理，來確保這些不同的水準層都能協同運作。

所以這是一個非常宏大的計畫。

And as a result, we have, to my surprise, as the chair of Ultra Ethernet, found that we're not the only ones that want this to be solved, right?

結果就是，身為 Ultra Ethernet 的主席，我驚訝地發現，不只我們想解決這個問題，對吧？

We've got over 100 different companies now.

現在我們有超過 100 家不同的公司。

It just recently passed over the 100 mark.

And we've got over 1,400 people who have actually sat into the meetings and contributed.

而且我們有超過 1400 人實際參與會議並貢獻心力。

It is an incredibly robust and diverse group of people from all over the planet.

這是一個非常強大且多元的團隊，成員來自世界各地。

So we've got people from the United States, from EMEA, from APAC.

所以我們有來自美國、EMEA、APAC 的成員。

So let's take a quick example of what it is that we're actually doing.

所以我們來快速舉個例子，看看我們實際在做什麼。

Generally speaking, when you have an enterprise data center and you're using Ethernet oh, I like the cameras.

一般來說，當你有一個企業資料中心，然後你正在使用乙太網路，喔，我喜歡這些攝影機。

So you have your general-purpose network, right?

所以你會有一個通用網路，對吧？

But when you're talking about a specific type of workload, you want to make sure that the network actually winds up doing what you want it to do.

但當你談到特定類型的負載時，你會想要確保網路確實能達到你想要的效果。

So you have backend networks for your AI and HPC workloads.

所以你會為你的 AI 和 HPC 負載準備後端網路。

And then you have a third network, a third type of backend network, if you want to do kind of scale-up.

然後你會有第三個網路，第三種後端網路，如果你想做那種擴展。

What's the difference between scale-up and scale-out?

擴展（scale-up）和橫向擴展（scale-out）有什麼差別？

Well, generally, in a very high-level view, the difference between scale-up and scale-out is that if I've got these accelerators, GPUs, and

嗯，一般來說，從非常高層次的觀點來看，擴展和橫向擴展的差別是，如果我有了這些加速器，GPU，

I need to connect them together, I need to make sure that the memory regions for the GPUs all act as one huge honking GPU.

我需要將它們連接在一起，我需要確保 GPU 的記憶體區域都像一個超大的 GPU 一樣運作。

I got one GPU here, another GPU here, another GPU here.

我這裡有一個 GPU，這裡有另一個 GPU，這裡還有一個 GPU。

And I'm going to scale this up so that it all looks like one GPU to do all the same work.

我會將它們擴展，讓它們看起來都像一個 GPU 來做所有相同的工作。
