The world’s largest computing processor chip

©Mark Ollig 


It is exceptionally larger in both physical size and processing capability than any other single computing chip used today.

Manufacturing of this chip requires a unique wafer-scale integration process used by Cerebras, a company located in Los Altos, CA.

A wafer (also called a substrate) is a thin, circular slice of silicon or other semiconducting material about 12 inches in diameter.

Computer chip components, such as memory or processors, are made using thin circular disks of silicon. One silicon disk is called a wafer. About 100 computer chips can be made on a single wafer.

Cerebras explained its unique wafer-scale integration process as making a single computing processor chip using most of the silicon wafer.

One Cerebras WSE (Wafer Scale Engine) computing chip measures nearly 8.5 inches by 8.5 inches, or slightly more than 72 square inches, which is about the size of your average dinner plate.

Each WSE chip holds an incredible 1.2 trillion transistors – yes, trillion.

By comparison, the AMD (Advanced Micro Devices) central processing unit chip measures 1.27 square inches and contains 32 billion transistors.

In 1984, placing one million transistors on a chip was reached, using ultra-large-scale integration.

Silicon chips are manufactured in chip fabrication facilities using methods much like a newspaper printing press.

The newspaper printing process uses ink; the silicon chip printing process uses photolithography, chemical deposition, and etching.

The chip fabrication facilities are located in super-clean rooms, where the folks wear those special white suits and head garb.

Let us compare the number of transistors in a WSE chip (1.2 trillion) with the amount used in the pocket-sized portable transistor radios we carried around with us back in the day.

Those small transistor radios contained up to eight electronic transistor components, used for amplifying or the switching of electronic signals.

Of course, today’s transistors are nanoscale-sized, and can only be seen using extremely powerful microscopes.

Before transistors, radios used vacuum tubes; but that is a topic for a future column.

In the digital computing world, transistors are mostly made of silicon or other semiconductor material.

They are used as a binary on-and-off switch to allow, or prevent current flow.

Transistors wired in specific combinations are the “logic gates” used in digital computing circuitry.

The WSE chip contains 400,000 programmable computing cores used for independent mathematical operations. These cores are small, fast, and include no volatile memory caches – think old-school RAM (Random Access Memory).

Cerebras said its WSE chip could be used in AI (artificial intelligence) research for neural networks requiring tremendous computing speed, memory, and communication bandwidth.

When installed, the WSE computing chip consumes a lot of power.

Heat radiated from the electronic transistors, and other components on the chip must be removed to keep the computing chip working.

This heat cannot be removed using conventional airflow cooling methods that are used with smaller wafer computing chips.

The larger wafers used with the WSE chip are manufactured with a “sandwiched cold plate” on top of the silicon.

Heat is removed by keeping the wafer’s silicon surface in physical contact with a metal manifold plate, which houses a vertically-mounted chilled-liquid cooling system.

With the heat removed from the wafer, the computing chips’ electronic components can operate at optimum efficiency.

The WSE chip will be used in commercial data centers and will assist with self-driving automobiles, gaming graphics, and artificial intelligence neural network research.

The computing chip is not available to the consumer market at this time.

Cerebras is to begin shipping orders to customers this month. They have not made public the cost of their WSE processing chip.

Dec. 23, 1947, a working transistor was demonstrated by scientists John Bardeen, Walter Brattain, and William Shockley inside Bell Laboratories in Murray Hill, NJ.

July 8, 1949, a patent was filed for a semiconductor amplifying device (hearing aid) with five transistors on a single substrate material by Dr. Phil Werner Jacobi.

MIT research results in 3D printing improvements

©Mark Ollig 


As a youngster, I remember walking downtown to the Dueber’s store on Main Avenue in Winsted, and buying a toy glider airplane made from balsa wood.

Back then (the 1960s), an airplane with a 12-inch wingspan, landing gear, and a rubberband-powered propeller cost a little more than $1 – or two weeks’ worth of allowance.

Some of us will remember carefully unpacking the parts from the plastic wrapper and cautiously assembling the thin balsa wood pieces of the canopy, rudder, wing, and stabilizer onto an approximately 8-inch long, square wooden dowel.

A plastic propeller and a landing gear consisting of two small plastic wheels spaced apart with a framed metal wire fastened to the front end section were included with the rubberband-powered airplane models.

The release of energy from a wound-up rubber band attached from the propeller to a small metal hook by the tail, powered the plane through the air. The tension from the rubber band is not released until we are ready for take-off.

I remember winding the propeller to put tension knots in the rubber band – always turn it clockwise.

Placing the plane upon a level surface, I released the tension on the rubber band. This, of course, caused the airplane to quickly race forward and take off into the wild blue yonder.

On a good day, a rubberband-powered airplane would fly about 150 feet – and hopefully, safely land on the ground without breaking any of the fragile balsa wood pieces.

So much for today’s nostalgia – let’s move ahead in time to today’s column topic.

Soon, your 3D printer will not just be printing out a plastic model plane; it will also be adding the electronic circuitry.

Researchers at Massachusetts Institute of Technology (MIT) recently announced a new printing method using filaments with embedded electronics to merge with 3D printed structures, objects, and devices.

“We established a fast, multiscale approach to print a diverse set of designable multi-material filament-based inks to create complex three-dimensional hierarchical functional systems,” read part of the MIT technical paper published in Nature Communications.

MIT researchers developed a special nozzle to attach on a conventional 3D printer, along with a new, unique fiber array filament polymer.

The fiber array filament will replace the single-filament polymers, which usually melt before being expelled through a standard 3D printer nozzle.

Their new filament polymer consists of a complex internal multiple fiber structure using various materials arranged in a precise configuration. The entire filament is coated with a polymer cladding.

An array of fibers within the filament contain precisely-placed electronic components; as per their planned design for functionality. Flashing lights in one 3D-created device would signal communication to fibers with light sensors. The associated electronics would receive and process any data.

The new nozzle operates at a lower temperature and pulls the new filament through it faster, allowing only partial melting of the outer filament layer. The internal portion of the filament containing the electronic circuitry stays cool, thus allowing the functions for the electronics to be unaffected.

The melted filament is pliable enough to be shaped and adhered into the structure being 3D printed.

Inside the internal material of the filament, thin, electric current-conducting metal wiring provides the path to power the semiconductors and other electronic components, controlling various device functions within the 3D printed device.

The filament’s internal polymer material acts as an insulator, which prevents the wiring from coming into contact with each other.

With a standard 3D printer, researchers at MIT created a model plane using its printer nozzle and unique filament containing eight different materials.

Before MIT’s demonstration of their light-flashing 3D model plane, Gabriel Loke, MIT doctoral student wrote, “A [3D] printer capable of depositing metals, semiconductors, and polymers in a single platform still did not exist, because printing each of these materials requires different hardware and techniques.”

The plastic, blue model airplane included flashing lights and electronic components, added using MIT’s new 3D printing method.

MIT sees its unique 3D nozzle printing process and embedded filament fiber technology used in robotics, communications, biomedical implant devices, and other designs containing sensors and electronics in the future.

Using this new method to 3D print working – rather than static – prototype devices are also seen as a valuable benefit.

The new MIT process is also said to be three times faster than current 3D structure fabricating methods.

We certainly have come a long way from the days of balsa wood and rubberband-powered toy airplanes; though, I did have a lot of fun flying them.

Wherever Apple Computer hosts one of its live events to announce a new or improved product, expect standing lines and filled seats.

The Apple Special Event recently took place inside the Steve Jobs Theater, located at Apple headquarters in Cupertino, CA.

Shortly after the program started, smiling Apple CEO Steve Cook took the stage to thunderous applause from the folks in attendance.

Attention was focused on the new Apple iPhone 11 smartphones, along with the series 5 Apple Watch; both products stole much of the thunder during the special event.

Apple introduced its new 5.8-inch display iPhone 11 Pro, starting at $999, and the 6.5-inch display iPhone 11 Pro Max, at $1,099.

The new iPhones will come in a color choice of black, white, yellow, red, green, and purple.

The iPhone 11 Pro and Max come equipped with the A13 Bionic chip. Apple said this new processor chip makes them the “fastest CPU (Central Processing Unit) and GPU (Graphics Processing Unit) ever in a smartphone.”

The iPhones also include a triple-lens camera system, which consists of a telephoto camera; full angle camera, that lets in 40 percent more light; and an ultra-wide camera with a 120-degree field of view. The cameras can film 4K resolution video at 30 frames per second.

The battery life for the iPhone Pro is 14 hours, while the iPhone Pro Max reportedly has 15 hours.

The new, less expensive iPhone 11 will sell for $699. It includes a 6.1-inch display screen, and a 12-megapixel camera on the front, allowing users to film slow-motion videos and wide-angle selfies.

Apple TV Plus, which will be competing against Netflix, is slated to launch Nov. 1, at a surprisingly low monthly cost of $4.99.

This monthly charge includes family access, whereby six family members can share one Apple TV Plus subscription. Each family member is allowed a user ID and password.

Apple TV Plus will include the sci-fi drama, “See,” “The Morning Show,” and “Dickinson,” a drama series; along with other original titles and shows to be announced.

The new Apple iPad with 10.2-inch retina display will be available in stores Sept. 30 for $329.

The new iPad includes an operating system called the iPadOS; previously, the iPad shared the same iOS operating system with the iPhone.

For the first time, the iPhone and iPad will be using independent operating systems.

Also included in the new iPad is an 8-megapixel camera, and Apple’s proprietary A10 Fusion processor chip.

Another product presented was the Apple Watch Series 5 for $399, with built-in GPS.

For $499, the Apple Watch Series 5 has added 4G network connectivity.

Both watches include an always-on retina display and 18-hour battery life.

A new low-temperature polysilicon and oxide display are on both watches. They come in stainless steel, ceramic, or titanium cases.

Apple Computer was founded by the late Steve Jobs, Steve Wozniak, and Ronald Wayne in 1976.

Billions of dollars lost in cyber scams


©Mark Ollig



Internet fraud is investigated by the FBI’s IC3 (Internet Crime Complaint Center).

On average, 900 complaints are received each day by the IC3, regarding fraud perpetrated on business and individuals.

Those perpetrating internet fraud and online scams are lawbreakers, both foreign and domestic.

The IC3 provides the public with a reporting tool for submitting information to the FBI concerning suspected internet-supported criminal activity.

Since its start in May 2000, the IC3 has received nearly 4.5 million complaints about online cyber scams.

From 2014 to 2018, $7.45 billion in total victim losses due to online criminal activity and cyber scams have been reported.

The FBI’s Cyber Division recently released its 2018 Internet Crime Report.

“We hope this report provides additional information of value as we work together to protect our nation against cyber threats,” read the message at the beginning of the report.

The IC3 report states a total of 351,936 complaints were filed from businesses and individuals, with losses exceeding $2.7 billion during 2018.

These complaints included the following internet crimes: extortion, tech support fraud, payroll diversion, confidence/romance fraud, personal data breach, non-payment/non-delivery, and business email compromise.

Online confidence/romance fraud occurs over online dating websites, phone apps, and social media networks, such as Facebook. This type of fraud involves a perpetrator deceiving their victim into believing they are in a trusting relationship.

A perpetrator may try to convince their victim they are a US citizen living in a foreign country, or with the US military deployed overseas. Some will claim to be a US business owner, promising profitable investments.

Once these perpetrators gain their victim’s trust, they will attempt to deceive and influence their actions.

The victim is persuaded into sending money, offering personal financial information, or making purchases on behalf of the perpetrator.

More than 18,000 people were defrauded out of more than $362 million because of internet confidence/romance fraud. This type of fraud targets mostly the elderly, women, and those who have lost a spouse.

Sometimes, an online perpetrator will invest months building trust with their victims before asking for money, saying they need it for “an emergency.”

The Better Business Bureau (BBB) reports, during the last three years, US and Canadian victims of online romance were defrauded out of nearly $1 billion.

Be cautious when using a dating website or app; instead of discovering a loving relationship, you might find yourself ending up as an unsuspecting accomplice in a money-laundering scheme.

In February, the BBB reported 30 percent of online romance fraud victims were used to launder money; these victims are known as “money mules.”

“The Mule” is a 2018 movie in which Clint Eastwood plays the part of Earl Stone, an elderly man who unknowingly (at first) becomes a money mule for a drug cartel. In the end, being a money mule didn’t work out too well for Stone.

Be suspicious when an online acquaintance suggests sending you money; you could find yourself ending up becoming their cyber money mule.

The IC3 works with local, state, federal, and international agencies. It acts as a central hub for public awareness, and for taking complaints from the victims of internet crime.

It also provides law enforcement with remote access to its IC3 database through the FBI’s Law Enforcement Enterprise Portal.

There were 14,408 complaints related to tech support fraud sent to the IC3. Victim losses in 2018 were almost $39 million. A majority of these tech support fraud victims were over the age of 60, which gave me pause for thought.

Criminal cyber investigations by the IC3 have resulted in indictments, arrests, convictions, and asset forfeitures from the perpetrators. Some victims have recovered part, or all of their monetary losses.
