Amazon and iRobot agree to terminate pending acquisition Amazon's proposed acquisition of iRobot has no path to regulatory approval in the European Union, preventing Amazon and iRobot from moving forward together-a loss for consumers, competition, and innovation. SEATTLE and BEDFORD, Mass., Jan. 29, 2024 /PRNewswire/ -- Today Amazon (NASDAQ: AMZN) and iRobot (NASDAQ: IRBT) announced that they have entered into a mutual agreement to terminate their previously announced acquisition agreement, originally signed on August 4, 2022, under which Amazon would have acquired iRobot for cash consideration. This deal would have allowed Amazon to invest in continued innovation by iRobot and support iRobot in lowering prices on products customers already love. The companies released the following statements today about the decision:
Quote from Linus Torvalds: "[Intel] threw out all the good parts of the x86 because people thought those parts were ugly. They aren't ugly, they're the 'charming oddity' that makes it do well."
“When the IA64 project was started it was perceived that the performance of RISC machines would outstrip that of [Complex Instruction Set Computing (CISC)] machines. ... They felt that they could get higher performance with a [Very Large Instruction Word (VLIW)] architecture than they could with a CISC architecture.” - Dave Cutler, "A History of Modern 64-bit Computing"

Post by Todd Austin on LinkedIn The TECH NEWS doesn't want to talk about it, but today EVERY computing system-every last one—is LITTLE ENDIAN. In the dark ages of computer architecture, there were big-endian and little-endian architectures, and it was TOTAL CHAOS. Through the leadership of myself and other HIGHLY TALENTED computer architects, it became clear that BIG ENDIAN was a TOTAL DISASTER, confusing, slow, and frankly a disgrace to the world of computing. Eventually, our sage leadership FIXED it, unified it, and made memory systems BEAUTIFUL again. Last year at HotChips, a very famous computer architect came up to me (with tears in their eyes) and said, "Thank you, professor, for bringing peace and harmony to our memory systems." Today everyone knows it: computer architects LOVE little endian. But now l've just learned something SHOCKING-maybe the biggest cover-up in the HISTORY of technology. The INTERNET-yes, the whole thing—is COMPLETELY BIG-ENDIAN! After all the tremendous work we did, shadowy standards committees and so-called networking "experts" quietly locked in BIG-ENDIAN as "network byte order." It's a GLOBAL DARK NET conspiracy designed to undermine our BEAUTIFUL memory systems and to bring back confusion, chaos, and misaligned data. We must now come together ONCE AGAIN TO BRING ORDER TO THE CHAOS. We must END big endian once and for all. We must make the Internet little endian and make it STRONGER than ever before. BIG-ENDIAN is for LOSERS-LITTLE-ENDIAN is for WINNERS. Thank you for your attention to this matter.
Todd Austin • • 1st S. Jack Hu Collegiate Professor of CSE at UofM... I am a COMPUTER ARCHITECT, which means I design computers. I was trained at a great school (UW-Madison), and I worked in industry (Intel) before I became a professor (University of Michigan). Despite these rarefied experiences, I first came to know computer architecture in the KITCHEN, working for 4 years first as a COOK. Let me explain. As a cook, you are the control logic of a complex multi-issue machine, which operates with many of the optimizations found in today's CPUs: IN-ORDER FETCH: The meal orders come in-order from the wait staff, and this order must be preserved. OUT-OF-ORDER ISSUE: With a big menu, the latency to cook items will vary greatly, from fast salads to medium-latency burgers to long-latency steaks. Cooks will scan the upcoming orders and "issue" long latency items first, medium later, and short last, to make sure all items finish at roughly the same time.

Stacy Rasgon, Analyst, Bernstein: a smaller wafer size. Got it. Got it. I guess along those lines, like, does China fit into all of this? And and and, clearly, you guys have been impacted by sort of increasing waves of export controls, which have not been all that fun. China was still buying a lot of especially those kinds of of of tools. Sometimes it's it's unclear to me who's actually doing the buying in China. I guess just how do we think about the general environment in China, the geopolitical situation? I always worry, like, what's the risk of further export controls? I mean, could could our, you know, our new president wake up one morning and, you know, after eating a bad burrito or something and decide to to cut everything off. I mean, this is something I I wish I don't think it's likely, but I wish I could say I thought that risk was non zero, and I'm not sure that it is. So, like, how does how does Lem think about those kinds of risks?

CASEY: You will often hear "people on the internet" say that ARM as an ISA is better for low power than x64. People like me who study ISAs tend to be skeptical of this claim. As a hardware designer, are there any specific things about the x64 ISA that you find difficult to deal with for low-power designs? MIKE: Having spent my career working on x86, I might have a bias here! I do think each ISA has its own quirks that influence some of the microarchitecture. But at the base level, we can build low-power x86 designs as well as ARM can, and ARM can build high frequency, high performance designs as well as x86 can. None of the quirks are really limiting you on the microarchitecture. The reality is that the markets we've been targeting have been different, so they've driven the architectures to optimize for different design points. ARM is in much lower power markets where x86 hasn't had the market share to chase.

CMV: The loud, principled opposition to the treatment of Mahmoud Khalil is tremendously counterproductive for opponents of Trump Recently I've seen a fairly loud social media outcry over the prospect of Mahmoud Khalil being targeted for his "speech" regarding Israel/Palestine. My view, is that this is a deeply counter persuasive manner of convincing people that supporting the Trump admin is a poor choice. Why do I think this? I personally believe that most people are not Constitutional maximalists, including those who are making this argument. A compelling analogue to me, is the other side's 2A maximalism; I'm positive almost all Khalil supporters would argue, that wife beaters and teenagers threatening to shoot up schools, should not be allowed to acquire of maintain firearms; nor should we normalize a gun in every classroom as the solution to school shooters. I know we've grown up identifying America as possessing a tradition of protest; this is more palatable when considered in the context of social times when minorities were institutionally identified as second class citizens with less rights. Now, we are attempting to apply this to green card holder, who is a leader of groups (at least to the average citizen) conflated with behaviors like shutting down classrooms at universities, threatening/intimidating Jews, shutting down highways with human chains, and preaching harm against America explicitly - all in the name of supporting groups that are equally genocidal in the other direction towards Jews! Those citing, "he was not charged with a crime!" are less persuasive as well - the casual onlooker will just conclude, "well, they have stopped prosecuting shoplifting, fare evasion, and are even freeing violent criminals w/o bail - why would this be any different?" Now, I am a centrist lib, and will absolutely not support Republicans, and think there are a million better, more persuasive reasons to oppose Trump. But I see this type of messaging and think, how does th…

From Brat’s Wikipedia page: Brat came to national prominence when he defeated the U.S. House Majority Leader, Eric Cantor, in the 2014 Republican primary in Virginia's 7th congressional district. His primary victory, which he achieved with the support of the Tea Party movement, made Brat the first primary challenger to oust a sitting House Majority Leader since the position's creation in 1899. 11 Brat went on to win the 2014 general election and was re-elected to Congress in 2016. During his congressional tenure, Brat was known as a conservative Republican and a member of the Freedom Caucus. He was defeated by Democrat Abigail Spanberger in the 2018 election. In January 2019, Brat was named dean of the Liberty University School of Business.

ipsum2 6 months ago | parent | context | favorite | on: Zen5's AVX512 Teardown and More The part of the article I found most amusing: "Intel added AVX512-VP2INTERSECT to Tiger Lake. But it was really slow. (microcoded ~25 cycles/46 uops) It was so slow that someone found a better way to implement its functionality without using the instruction itself. Intel deprecates the instruction and removes it from all processors after Tiger Lake. (ignoring the fact that early Alder Lake unofficially also had it) AMD adds it to Zen5. So just as Intel kills off VPZINTERSECT, AMD shows up with it. Needless to say, Zen5 had probably already taped out by the time Intel deprecated the instruction. So VPZINTERSECT made it into Zen5's design and wasn't going to be removed. But how good is AMD's implementation? Let's look at AIDA64's dumps for Granite Ridge: AVX512_VP2INTERSECT :VP2INTERSECTQ k1+1, zmm, zmm L: [diff. reg. set] T: 0.23ns= 1.00c Yes, that's right. 1 cycle throughput. ONE cycle. I can't... I just can't... Intel was so bad at this that they dropped the instruction. And now AMD finally appears and shows them how it's done - 2 years too late."
From @InstLatX64: “A very nice phrase search example from Gabriel Menezes, showing the usefulness of the #AVX512. -_VP2INTERSECT instruction - too bad it's deprecated on #Intel processors and its future on #AMD #Zen6 is unclear” Reply by Leslie Barnes (@LeslieB82382206): “#AVX512_VP2INTERSECT will continue to be supported in AMD processors going forward”

Snippet of the AMD Processor Programming Reference (PPR) 8.1.1 Background The Infinity Fabric™ (also known as "Fabric", or as "DE") is a scalable and modular coherent interconnect for the EPYC™ Server SOC (System On Chip). The following abstract block diagram of an IOD shows the some of the key interfaces of the Infinity Fabric. In this conceptual rendering, there are a certain number of CPU Moderator blocks (CCMs), 10 Moderator blocks (LOMs), Coherent Stations (CSs), and Infinity Link Controller blocks (LINKs). While the Infinity Fabric stretches across IODs over the xGMI Infinity Links, the Fabric interface blocks are associated with a given IOD. Figure 39: Infinity Fabric'™ Interconnect Table 168: Interface Descriptions Interface Descriptions CS Coherent Station (Interface to one UMC instance) ССМ CPU Moderator (interface to one or two CCD instances) IOM IO Moderator (interface to one NBIO instance) LINK Interface to inter-socket Infinity Fabric GMI link
Infinity Fabric has CPU and GPU dies talk to Coherent Master (CM) blocks, which abstract out the rest of Infinity Fabric from that compute block's perspective. The CM has a memory map, and sends packets (flits) addressed to whichever agent is responsible for the requested memory address. Then, a network of buses, switches, and off-die interfaces ensure the flit reaches its destination. <diagram> Most CPU and GPU requests go to physical addresses backed by DRAM. Coherent Slaves (CS) handle those addresses, and are responsible for ensuring requests are satisfied with the most up-to-date data. To carry this out, the CS has a probe filter, and is attached to a memory controller.
