Introducing the mentor organizations for Google Summer of Code 2018

Monday, February 12, 2018

We are pleased to announce the open source projects and organizations that were accepted for Google Summer of Code 2018! As usual, we received more applications this year than we did last year, and nearly twice as many as we are able to accept into the program.

After careful review, we have chosen 212 applicants to be mentor organizations this year, 19% of which are new to the program. Please see the program website for a complete list of the accepted organizations.

Are you a student interested in participating? We begin accepting student applications on Monday, March 12, 2018 at 16:00 UTC and the deadline to apply is Tuesday, March 27, 2018 at 16:00 UTC.

The most successful applications come from students who start preparing now. You can start by watching the video below, checking out the Student Guide, and reviewing the list of accepted organizations.

You can find more information on our website, including a full timeline of important dates. We also highly recommend perusing the FAQ and Program Rules.

A hearty congratulations–and thank you–to all of our mentor organizations! We look forward to working with all of you during Google Summer of Code 2018.

The cpu_features library

Wednesday, February 7, 2018

"Write Once, Run Anywhere." That was the promise of Java back in the 1990s. You could write your Java code on one platform, and it would run on any CPU implementing a Java Virtual Machine.

But for developers who need to squeeze every bit of performance out of their applications, that's not enough. Since the dawn of computing, performance-minded programmers have used insights about hardware to fine tune their code.

Let's say you're working on code for which speed is paramount, perhaps a new video codec or a library to process tensors. There are individual instructions that will dramatically improve performance, like fused multiply-add, as well as entire instruction sets like SSE2 and AVX, that can give the critical portions of your code a speed boost.

Here's the problem: there's no way to know a priori which instructions your CPU supports. Identifying the CPU manufacturer isn't sufficient. For instance, Intel’s Haswell architecture supports the AVX2 instruction set, while Sandy Bridge doesn't. Some developers resort to desperate measures like reading /proc/cpuinfo to identify the CPU and then consulting hardcoded mappings of CPU IDs to instructions.

Enter cpu_features, a small, fast, and simple open source library to report CPU features at runtime. Written in C99 for maximum portability, it allocates no memory and is suitable for implementing fundamental functions and running in sandboxed environments.

The library currently supports x86, ARM/AArch64, and MIPS processors, and we'll be adding to it as the need arises. We also welcome contributions from others interested in making programs “write once, run fast everywhere.”

Announcing the Winners of Google Code-in 2017

Wednesday, January 31, 2018

Google Code-in (GCI) 2017 was epic in every regard. It was a very, very busy 7 weeks for everyone - we had 3,555 students from 78 countries completing 16,468 tasks with a record 25 open source organizations!

Today we are excited to announce the Grand Prize Winners and Finalists with each organization. The 50 Grand Prize Winners completed an impressive 1,739 tasks between them while also helping other students.

Each of the Grand Prize Winners will be awarded a four day trip to Google’s campus in northern California to meet with Google engineers, meet with one of the mentors they worked with during the contest, and enjoy some fun in the California sun with the other winners. We look forward to meeting these winners in a few months!

GCI is a contest that the Google Open Source team is honored to run every year. We saw immense growth this year, the seventh year of the contest, both in the number of students participating and the number of countries represented by these students. 

Our 730+ mentors, the heart and soul of GCI, are the reason the contest thrives. Mentors volunteer their time to help these bright students become open source contributors. Mentors spend hundreds of hours during their holiday breaks answering questions, reviewing submitted tasks, and welcoming the students to their communities. GCI would not be possible without their patience and tireless efforts.

We will post more statistics and fun stories that came from GCI 2017 here on the Google Open Source Blog over the next few months, so please stay tuned!

Congratulations to our Grand Prize Winners, Finalists, and all of the students who spent the last couple of months learning about and contributing to open source.
