Cerebras puts ‘world’s largest computer chip’ in Lassen supercomputer

Noble Horvath

Lawrence Livermore National Laboratory (LLNL) said it has integrated Cerebras Systems‘ new product, which the company claims is the world’s largest computer chip, into its Lassen supercomputer for the National Nuclear Security Administration.

Technicians recently connected the Silicon Valley-based company’s massive, 1.2 trillion transistor Wafer Scale Engine (WSE) chip — designed specifically for machine learning and AI applications — to the 23-petaflop Lassen. The new wafer-sized computer chip will help accelerate AI research at LLNL. The National Nuclear Security Administration tests the nation’s stockpiles of nuclear weapons using the IBM and Nvidia-based Sierra system, to which Lassen is the unclassified companion. It is No. 14 on the latest Top 500 List of the world’s most powerful supercomputers.

Normally, chip makers slice a wafer from a 12-inch diameter ingot of silicon to process in a chip factory. Once processed, the wafer is sliced into hundreds of separate chips that can be

CBP: Mantis eggs found in computer mouse in Philadelphia

CBP discovered mantis egg masses concealed inside a PC gaming mouse.

U.S. Customs and Border Protection

A computer gaming mouse surprised U.S. Customs and Border Protection officials when an X-ray revealed mantis eggs inside.

Officials in Philadelphia found mantis eggs inside the device earlier this month, the agency said in Thursday.

“U.S. Customs and Border Protection agriculture specialists in Philadelphia have seen many insects, mostly as hitchhikers stowing away on a produce shipment or burrowed into wood packaging material,” the agency said in a news release. “But finding mantis eggs inside a computer gaming mouse is a first.”

Officers X-rayed a package heading to New Hampshire on Aug. 7 that appeared to be a wireless computer gaming mouse from Spain, according to CBP. They “detected anomalies” in the mouse and discovered three brown sacks and a live insect hidden inside.

IBM doubles its quantum computer performance

Noble Horvath

IBM has doubled the performance of its quantum computers compared with last year’s model, a key step in delivering on the promise of the revolutionary machines. But it’s only an early step, and rivals are breathing down Big Blue’s neck.

The fundamental data processing element in a quantum computer is called a qubit, and having more of them is better. They’re notoriously finicky, though, because outside influences like heat easily perturb them and derail quantum calculations. To best measure performance, IBM created a test called quantum volume that’s designed to reflect both how many qubits a quantum computer has and how much work they actually accomplish.

In 2019, IBM reached a quantum volume of 32. This year, it reached 64, adding a second year to its plan to double quantum volume annually. That

The Golden Age of computer user groups

The Homebrew Computer Club where the Apple I got its start is deservedly famous—but it’s far from tech history’s only community gathering centered on CPUs. Throughout the 70s and into the 90s, groups around the world helped hapless users figure out their computer systems, learn about technology trends, and discover the latest whiz-bang applications. And these groups didn’t stick to Slacks, email threads, or forums; the meetings often happened IRL.

But to my dismay, many young technically-inclined whippersnappers are completely unaware of computer user groups’ existence and their importance in the personal computer’s development. That’s a damned shame. Our current reality may largely be isolated to screens, but these organizations helped countless enthusiasts find community because of them. Computer groups celebrated

The Racist Legacy of Computer-Generated Humans

Noble Horvath

Computer-generated imagery is supposed to be one of the success stories of computer science. Starting in the 1970s, the algorithms for realistically depicting digital worlds were developed in a monumental joint effort between academic, commercial and federal research labs. Today, we stream the results onto the screens in our homes. Escaping into worlds where computer-generated superheroes right all wrongs, or toys come to life to comfort us, are welcome respites from stories of real-life systemic racism, the ubiquitous dimensions of which are becoming clearer every day.

Alas, this technology has an insidious, racist legacy all its own.

For almost two decades, I have worked on the science and technology behind movies. I was formerly a senior research scientist at Pixar and am currently a professor at Yale. If you have seen a blockbuster movie in the last decade, you have seen my work. I got my start at Rhythm and

What To Do When Your Computer Is Attacked

Noble Horvath

Moran Zavdi is the founder of Nucleon Cyber, which provides actionable, proactive cyber threat intelligence for organizations. 

I bet you can see the scene before you now: The hair on the back of your neck stands up, and the panic creeps up your spine as you face your computer with dread — the screen has turned black. A message informs you that you’re under attack. Pay the ransom, or the person on the other end will erase your computer memory, steal files or share private information such as secure customer data. You freeze. What do you do next?

Your gut instinct may be to quickly press the power button and shut down the computer or run to an expert for help. Before you do, you should check a couple of items to reduce any damaging effects. Follow these easy steps to make sure you make the right choices

California to fix coronavirus reporting system amid backlog

A series of data failures has created a backlog of as many as 300,000 test results in California, the state’s top health official said Friday as he provided the first public explanation of a problem that has stymied efforts to understand the spread of the coronavirus.

California Health and Human Services Secretary Dr. Mark Ghaly said the state is developing a new coronavirus tracking system due to the recent deficiencies of the California Reportable Disease Information Exchange, a clearinghouse for state testing data known as CalREDIE.

“Simply put, the CalREDIE system was not built for this volume of data,” said Ghaly. “In order to create a lasting solution, we are accelerating the development of a new laboratory reporting system for COVID-19.”

Ghaly said the state would work through the backlog of records, which include COVID-19 tests and other health results, over the next 24 to 48 hours. He said state

Computer Definition & Meaning | What is a Computer?

Main » TERM » C »

By Vangie Beal

A computer is a programmable machine. The two principal characteristics of a computer are: It responds to a specific set of instructions in a well-defined manner and it can execute a prerecorded list of instructions (a program).

Modern Computers Defined

Modern computers are electronic and digital. The actual machinery wires, transistors, and circuits is called hardware; the instructions and data are called software.

All general-purpose computers require the following hardware components:

In addition to these components, many others make it possible for the basic components to work together efficiently. For example, every computer requires a bus that transmits data from one part of the computer to another.

Computer Classification: By Size and Power

Most people associate a personal computer (PC) with the phrase computer.  A PC is a small and relatively inexpensive computer designed for an individual
