There is a lot of news about compute being the bottleneck for AI. There is less visibility into the engineering it takes to make large-scale compute actually work reliably.
In my view, this is one of the most interesting computer science problems in the industry right now. It is not just about getting more GPUs. It is about making every layer of the system work: networking, scheduling, hardware health, storage, orchestration, reliability, observability, security, and the developer experience for researchers.
This blog gives a rare preview into the depth of engineering happening across the stack at OpenAI, starting with MRC and supercomputer networking. We're excited to start sharing more about designing, building, and operating compute at planet scale.

AI supercomputers need a new kind of network to stay in sync at massive scale.
OpenAI’s @markjhandley and @poyntingatgreg join @AndrewMayne to discuss what it takes to move data across record numbers of chips reliably and efficiently, the new Multipath Reliable Connection (MRC) networking protocol, and why it's available for the whole industry to use.

We’ve partnered with @AMD, @Broadcom, @Intel, @Microsoft, and @NVIDIA, to release Multipath Reliable Connection (MRC), a new open networking protocol that helps large AI training clusters run faster and more reliably, with less wasted GPU time.

When I became a wheelchair user, I thought coastline trails had become inaccessible to me. Fortunately, I was wrong!
On a three day adventure in North Wales, I explored some of the accessible sections of @WalesCoastPath for @countrylivinguk:

My uncle @MarkJHandley turned up this weekend with an all-terrain wheelchair he's designed & made!
Can't express what it means to be back on my favourite trails.
Getting my freedom back one muddy path at a time 💛

In the past 10 years, Japan has moved at a tremendous pace to install elevators & escalators in subway and train stations for the disabled and the elderly. These wheelchair accessible escalators are unique to Japan

This is unspeakably idiotic.

No one in or around SAGE and Nervtag is aware of any scientific advice given to the PM that the requirement to isolate for those infected with Covid19 should be terminated from end of the month. “It’s politics, isn’t it” is a typical reaction

So much of what we observe in the COVID data is driven by age dynamics - cases rising and falling in different age groups at different times.
Here's the full tapestry of the pandemic in England (for cases at least). So many different stories written into this plot.

NEW: first thread of 2022 is an Omicron situation update, starting with a detailed look at UK hospitals, before going international.
Let’s start with severity, and the most important chart:
Despite steep rises in cases and patients, the number on ventilators has barely risen.

* COVID THREAD ON BEST WE CAN DO LONG TERM *
Yes we’re in an acute crisis with Omicron and that needs dealing with, but it has actually made me want to think a lot about how this horrible pandemic ends, maybe you too? Let’s go through it…
1/35 (sorry, but this is troubling me)

IMPORTANT:
RAPID TESTS DO WORK WITH OMICRON
"But why are some people staying negative in the first days they have symptoms??"
This is expected. Symptoms don't = contagious virus
This is literally a reflection of the fact that vaccines are doing their job!
