Software

A system developed by researchers at MIT and Stony Brook University should make it easier for researchers to solve complex computational problems using dynamic programming optimized for multicore chips — without the expertise that such programming typically requires.

Faster programs, easier programming

New system lets nonexperts optimize programs that run on multiprocessor chips.

“Gitless" removes complicated concepts like "staging" and "stashing," without fundamentally changing Git's core functionality.

Making it easier to collaborate on code

CSAIL team's “Gitless” fixes Git’s biggest issues — and suggests their approach could help improve systems like Gmail and Dropbox.

“We want to see, in the next five years or so, the amount of time you need to search for parking spot in a city drop from around 35 to 40 minutes, to less than five minutes,” says Smarking co-founder Wen Sang PhD ’14.

Optimizing parking in the busiest places

Data-analytics platform helps parking managers meet driver demand in high-traffic areas.

To demonstrate Foundry, MIT researchers designed and fabricated skis with retro-reflective surfaces, a ping-pong paddle, a helmet, and even a bone that may someday be used for surgical planning.

Designing for 3-D printing

“Foundry” tool from the Computer Science and Artificial Intelligence Lab lets you design a wide range of multi-material 3-D-printed objects.

Researchers have designed a new programming language that lets application developers manage memory more efficiently in programs that deal with scattered data points in large data sets. In tests on several common algorithms, programs written in the new language were four times as fast as those written in existing languages.

Faster parallel computing

New programming language delivers fourfold speedups on problems common in the age of big data.

Accelerometers around patients' necks capture data about the motions of their vocal folds to determine if their vocal behavior was normal or abnormal.

How machine learning can help with voice disorders

By detecting signs of vocal misuse, system from CSAIL and Mass General could eventually be used to help diagnose voice disorders.

Simulations written in Simit, a new programming language, were dozens or even hundreds of times as fast as those written in existing simulation languages. But they required only one-tenth as much code as meticulously hand-optimized simulations that could achieve similar execution speeds.

User-friendly language for programming efficient simulations

New language can speed up computer simulations 200-fold or reduce the code they require by 90 percent.

A new database interface looks like a spreadsheet. Users don’t need to know database scripting languages such as SQL to create new database queries.

Democratizing databases

With a new tool, any competent spreadsheet user can construct custom database interfaces.

The researchers’ compiler takes as input differential equations and translates them into voltages and current flows across an analog chip.

Analog computing returns

New analog compiler could help enable simulation of whole organs and even organisms.

“Multicore systems are really hard to program,” says Daniel Sanchez, an assistant professor in MIT’s Department of Electrical Engineering and Computer Science. “You have to explicitly divide the work that you’re doing into tasks, and then you need to enforce some synchronization between tasks accessing shared data. What this architecture does, essentially, is to remove all sorts of expli...

Parallel programming made easy

New chip design makes parallel programs run many times faster and requires one-tenth the code.

“It’s very inspiring to see how these [hair-like] structures occur in nature and how they can achieve different functions,” says Jifei Ou, a graduate student in media arts and sciences at MIT. “We’re just trying to think how can we fully utilize the potential of 3-D printing, and create new functional materials whose properties are easily tunable and controllable.” Pictured is an examp...

Need hair? Press “print”

With fur, brushes, and bristles, Media Lab’s technique opens new frontier in 3-D printing.

As an undergraduate at MIT, Ned Burnell began thinking about the entire process of making products, and all of the decisions that lead to designing products in a particular way. This is what motivated him to pursue mechanical engineering.

Using engineering savvy to improve product designs

From windmills to software, graduate student Ned Burnell creates better tools.

“[T]oday, if you want to write a program, you go and bring in these huge frameworks and these huge pieces of functionality that you then glue together, and you write a little code to get them to interact with each other. If you don’t understand what that big framework is doing, you’re not even going to know where your program is going to start executing,” says Armando Solar-Lezama.

Automatic bug finder

System could make complex analysis practical for programs that import huge swaths of code.

Since 2013, John Hart (standing, center) has been teaching the MIT graduate course 2.S998 (Additive Manufacturing), which explores the fundamentals of 3-D printing.

3-D Printing 101

As MIT course challenges students to reinvent 3-D printing, professor aims to share approach with others.
