Concerning defects and yield, my understanding is that they bypass/don't use dead parts of the chip. They loose some random cores, but the chip as a whole still works.

[@egomatthisum]

Dr. Cutress did a great video on the Cerebras WSE-2 some time ago where he explained this.

[@deefdragon]

My favorite part of learning about these was that the cerbras chip actually had to INCREASE their yield because of the error count. There too much of the chip dedicated to error bypass, and in v2 they used like 2% of what they planned for errors previously.

[@rynz_2893]

woah!! that was my question. interesting!!

[@eclipsegst9419]

you know, anything less than the highest tier cpus on the market, have dead cores, (ie, a 6 core cpu has 8 cores and 2 are dead or disabled) nothing new really. One thing that bugs me though is why they don't sell the odd number core counts as is as lesser models of the one above, (ie, a 5 core entry level i5/r5, look they even match!)

I feel like this is missing one important thing(or rather, misinforming about it) - how they handle defects in WSE2. Because there is no waste due to manufacturing errors with WSE. They know they won't get a perfect wafer-sized chip, so they basically built in the tech to disable a few (hundred/thousand) cores, giving them a basically perfect yield of functioning chips. So while other chips have to get thrown out because they're just broken, with WSE they just route around the defects and still get their tens of thousands of cores.

These big wafer-scale CPUs you guys are talking about don't really have the same problems consumer-grade CPUs like Ryzen do when it comes to yields... Every individual core is wired in such a way that it can easily be disabled without much impact to performence, the only downside of that approach is that you can not cherrypick your chips .

Thats not a desktop PC. For all its amazing computing power, its not actually faster than your desktop cpu for everyday tasks you might run (like browsing the internet, watching youtube, playing games, running photoshop). Its made to run lots of task parallel. Like servers. Think gpu. Gpu's have hundreds or thousands of (more or less specialized) cores. Im guessing that the cores in this cpu are more general purpose than the ones in gpu's (thats why its so big)... Or that was my understanding. I admit i didnt listen all that closely the video.

I would love to know what makes this possible or at least viable now when it wasn't before. I understand that ship defects are an invitability so is there some type of error correction that allows them to do this? Have they managed to shrink the size of each chip relative to the entire die that they just run a full die as a chip and bypass the faulty chips? Or have the error rates gotten to a point where the occasional full die can have no errors when they are binned? I would love to know what makes this the best option now when until now we've seen alternative methods for current data centre needs. Thanks for another awesome video!

Increased demand for supercomputers. You can get the same result by throwing (more) discrete chips at it, with the upside that those chips can be useful for other applications. This thing?
