Deep Learning for Network Engineers
Toni PasanenModern Deep Learning models can be extremely large, often exceeding the memory capacity of a single GPU or CPU. In these cases, training must be distributed across multiple processors. This introduces the need for high-speed communication between GPUs—both within a single server and across multiple servers.
Intra-node GPU communication typically relies on high-speed interconnects like NVLink, with Direct Memory Access operations enabling efficient data transfers between GPUs. Inter-node communication, however, depends on the backend network, either InfiniBand or Ethernet-based. Synchronization of model parameters across GPUs places strict requirements on the network: high throughput, ultra-low latency, and zero packet loss. Achieving this in an Ethernet fabric is challenging but possible.
This is where datacenter networking meets Deep Learning. Understanding how GPUs communicate and what the network must deliver is essential for designing effective AI data center infrastructures.

Authors have earned$14,548,517writing, publishing and selling on Leanpub.
You can either write your book in Markdown or you can upload PDF or EPUB files to sell in our store.
If you are writing in Markdown, you can use our simple in-browser text editor, or you can write on your computer and sync with GitHub or Dropbox. Either way, you can publish your Leanpub ebook with one click. You can publish your book while you're writing it, or wait until it is done: it's up to you.
You can create a Leanpub course in Markdown as well. Leanpub courses are like Leanpub books, but with quizzes and exercises that learners complete on the Leanpub website to earn a certificate of completion. To learn more about how to create a Leanpub course, you can watch this video on YouTube which shows the entire process from signup to publish!

Leanpub: Publish Early, Publish Often
On Leanpub, you can publish your book while you write it, and earn 80% royalties.
We call this Lean Publishing, and it's why Leanpub exists. Lean Publishing is the act of publishing an in-progress book using lightweight tools and many iterations to get reader feedback, pivot until you have the right book and build traction once you do. You can learn more about Lean Publishing in The Lean Publishing Manifesto, or watch the Tools of Change conference talk about it. There's even a book about these ideas, which still guide us today.
Leanpub is a magical typewriter for authors: just write in plain text, and to preview or publish your ebook, just click a button. On Leanpub, you can write in Markdown and generate your ebook with one click. (Markdown is really easy: everything you need to know is in the template we set up for you when you create a new book.)
Now, if you have completed a book already or if you have a writing workflow you prefer, you can also just upload your own PDF or EPUB files and click a button to publish them.
Whether you're writing in Markdown or uploading PDF and EPUB files, Leanpub is the best place to write, publish and sell in-progress and completed ebooks, with coupons, variable pricing, bundles and more. Besides how easy we make everything and the excellent support we provide, the other reason authors love Leanpub is our 80% royalty rate.
We pay 80% royalties on purchases of $7.99 or more, and 80% royalties minus a 50 cent flat fee on purchases between $0.99 and $7.98.
You earn $8 on a $10 sale, and $16 on a $20 sale.
So, if we sell 5000 copies of your book for $20, you'll earn $80,000. Yes, some authors have already earned much more than that on Leanpub. In fact, authors have earned over $14 million USD writing, publishing and selling on Leanpub.
Finally, Leanpub also supports publishing online courses, using the same Lean Publishing approach and Markdown-based workflow that we use for ebooks, and paying the same 80% royalties! To learn more, just create a course: the new course will contain a template which shows you how to get started.
Leanpub Promotes Authors
Leanpub does a lot to promote authors and their books. We constantly promote books on social media, especially new releases and bestsellers. We create short videos to help promote selected new books, and you can apply to have us record and produce a book launch video with you - for free. Leanpub co-founder Len Epp also records in-depth long-form interviews with select authors for our Frontmatter podcast, and we provide you with a range of marketing tools, from custom coupons to affordably-priced sponsored spots in our Weekly and Monthly newsletter sales.
Reader Memberships
A Reader Membership is a great deal, and it's a great way to support Leanpub authors and Leanpub!
First, a Leanpub Reader Membership gives you you free access to about 2000 books on Leanpub that are only free with membership. This includes hundreds of books about computer programming, data science, software architecture and more!
Half of the money from Reader Memberships goes directly to the authors of the books that you get for free with your membership. The other half helps us build a better Leanpub for our authors and our readers.
The Leanpub 60 Day 100% Happiness Guarantee
Within 60 days of purchase you can get a 100% refund on any Leanpub purchase, in two clicks.
Now, this is technically risky for us, since you'll have the book or course files either way. But we're so confident in our products and services, and in our authors and readers, that we're happy to offer a full money back guarantee for everything we sell.
You can only find out how good something is by trying it, and because of our 100% money back guarantee there's literally no risk to do so!
So, there's no reason not to click the Add to Cart button, is there?
