The Ledger
Every statement that passed quotation and attribution checks. Mix any filter with any other: certainty 1/5, debate potential 5/5, or both at once.
why aren't all 12 resolved? a statement only gets an assessment when the public record can support or contradict it. opinions and what-ifs never can, and 0 checkable ones are still open, waiting for their date. predictions held up or didn't; assertions are supported or contradicted. on every card: ▮▮▮▮▮ certainty · ▮▮▮▮▮ debate potential. speakers are clickable
Cerebras built the first supercomputer designed end-to-end for AI
“And it's also the first supercomputer that has been designed from beginning to end for artificial intelligence and deep learning.”
The Cerebras Wafer Scale Engine is the world's largest processor
“This is the world's largest processor.”
Cerebras's WSE is the first chip with over 1 trillion transistors
“It is the first part that has over a trillion transistors, and we're here, and at 1.2, and it has 400,000 sparse linear algebra cores on it.”
Cerebras's WSE delivers 9 petabytes per second of memory bandwidth
“There's 18 gigabytes of memory right, right on that, ah, on that silicon wafer, and it gives an unprecedented nine gigabytes per second, sorry, nine petabytes per second of memory bandwidth.”
Cerebras routes around manufacturing defects across its 400,000 cores
“By having 400,000 independent cores, it's perfectly fine if we have a few hundred defects on there, and it's only our job to route the information flows around those defects.”
Cerebras's chip provides 10,000x the memory bandwidth of standard GPUs
“So, having solved this, we were left with a machine that was pretty impressive on most of the metrics, being larger, more cores, 10,000 times the memory bandwidth and 33,000 times the fabric bandwidth.”
Cerebras's first customer was the U.S. National Labs
“It's pretty unusual in Silicon Valley to have your first customer be the U.S. National Labs”
No motherboard had ever housed a processor as large as Cerebras's
“No one before had ever put a processor that large in a motherboard, and so we had to also make a system to house this thing.”
Cerebras CS-1 system enclosure contains a single wafer plus cooling hardware
“There's only one wafer mounted in there, and the entire rest of this is about, ah, cooling and power delivery.”
Cerebras maps neural network layers across 400,000 chip cores
“We have, ah, an optimization solver that places these over the 400,000 cores.”
