Linux Foundation, Intel Pick ACRN for IoT

March 20, 2018

The Linux Foundation is pushing a new hypervisor effort called ACRN aimed specifically at IoT.

ACRN is smaller than other hypervisors, so better suited to embedded applications within the connected car. The U.K. Register reports that ACRN is powered by 25,000 lines of code. It says that’s far fewer than 150,000-plus lines found in other hypervisors.

Plus, ACRN hypervisors will be able to prioritize traffic. That’ll be important for connected car applications too. That means safety-related workloads can get priority over entertainment-related traffic within connected vehicles.

“With project ACRN, embedded developers have a new, immediately available hypervisor option,” said Jim Zemlin. The Linux Foundation executive director adds that ACRN is optimized for resource-constrained devices.

ACRN uses a Linux-based Service OS and can run other OSs. Intel Corp. is the key contributor to this embedded reference hypervisor project. And the Register says “it looks like the ACRN hasn’t fallen far from the x86 tree.”

In its press release, The Linux Foundation includes quotes from ADLINK, Aptiv, LG, and Neusoft Automotive.

“As Intel’s strategic partner, Neusoft is pleased to join Intel in project ACRN,” said Meng Lingjun. “ACRN has landed in China’s automotive electronics industry with practical implementation. I believe ACRN can meet the development requirements of IoT technology. We’re pleased to work with open source communities and introduce ACRN into the ecosystem.”

ADLINK CTO Angelo Corsaro said the lack of open source virtualization hindered IoT and fog computing. He added that ACRN brings the agility and manageability of virtualized environments into embedded, real-time systems.

“This will be a key enabler toward making the Industrial Internet of Things happen for real,” Corsaro continued.

Day 4, Cisco Live! - The Wrap

Day 4 was the final day of our first ever Cisco Live! We had a great show, with many great conversations and new connections with existing and potential end users, resellers, partners and job hunters.

Day 3, Cisco Live!

Day 3 of Cisco Live is history! For Fiber Mountain, we continued to enjoy visits from decision makers and influencers who were eager to share their data center and structured cabling challenges.

Day 2, Cisco Live!

Tuesday was Day 2 of Cisco Live for Fiber Mountain and we continued to experience high levels of traffic, with many high value decision makers and influencers visiting our booth. One very interesting difference from most conferences I attend is that there are no titles on anyone's show badges. This allows open conversations without people being pretentious. I think this is a very good idea.

Day 1, Cisco Live!

Fiber Mountain is exhibiting at Cisco Live! In Las Vegas for the first time ever! Our first day was hugely successful from just about any perspective - from quantity and quality of booth visitors to successful meetings with customers.
