Enzian updates

We post major updates and a periodic summary to the mailing list


Enzian demo video from the IAP Cloud Workshop now online

A couple of weeks ago, we presented Enzian at the Industry-Academia Partnership (IAP) University of Washington University/UC Berkeley/NYU Workshop on the Future of Cloud Computing Applications and Infrastructure.

Coyote paper presented at OSDI 2020

Coyote, our first candidate for an operating system for FPGAs, was presented by Dario Korolija last week at OSDI 2020. You can read the paper, look at the slides, and watch Dario’s presentation online here.

The first Enzian single board is working!

We are delighted to announce that the first single-board Enzian machine is working! Here is a picture of the first working board:

The CPU is up!

Today had a few white-knuckle moments with power sequencing, but in the end this has been a really great day!

Enzian power on test teaser

A somewhat nerve-wracking time in the Enzian team as the Swiss lockdown is relaxed:

Assembled Enzian v.1.3 board

When we got the first boards back late last year, they were not functional - in particular, an error in the design made it impossible to power up the FPGA or CPU. This was caught by the company doing the assembly, so we didn’t have the two big chips soldered on.

Long-overdue updates

We’ve been pretty quiet about Enzian over the last few months, but plenty has been happening behind the scenes despite the difficult times we’re going through. Best wishes for good health to everyone reading this.

Paper on Enzian accepted to CIDR 2020

In October we had a paper on Enzian accepted to CIDR 2020 - the Conference on Innovative Data Systems Research, held in Amsterdam this January!

Updates, at last!

It’s been a long time since we posted an update to the Enzian site, for which we apologize! It’s not that little has been happening - quite the opposite!

We have a board, sort of...

We have a first run of fabricated test boards for Enzian. Here’s what they look like (with pen for scale):

Board render!

Here’s a 3D render of the eATX-format Enzian board.

Team update

It’s been a while since we updated list of team members for Enzian.

Enzian power distribution boards

We’ve now got a power distribution board back from manufacture. David designed this to help us build a mock-up Enzian power and clock distribution network so Adam can write and test the Board Management Controller software.

We've signed off on the schematic

We’ve finalized the schematic for the first revision of the Enzian single board, and Dream Chip have now started PCB layout. Many thanks to everyone at ETH, Cavium, and Xilinx who helped review the draft schematics and spot issues!

FPGA-side DDR4 controller

Thanks to Zeke, we now have a working DDR4 controller for the FPGA-side of Enzian integrated with the (prototype) donut/shell.

Linux is up!

Thanks to some great TianoCore hacking from Adam, we now have Linux (and Barrelfish…) reliably booting on the ThunderX side of the Enzian prototype machines! This also gives us a solid software base for booting the final production board when it arrives.

We have an OUI!

We’ve successfully applied to the IEEE for an Organizationally Unique Identifier (OUI), since we’re going to need at least 7 MAC addresses per Enzian system (1 for the BMC, 2 for the ThunderX, and at least 4 for the FPGA 100Gb/s interfaces). Enzian how has a Large MAC address block assigned: 0C:53:31.

Mothy gave talks at Boston University and MIT

Prof. Mothy Roscoe gave the “Red Hat Collaboratory at Boston University Colloquium” on April 19th and presented the following day at the IAP workshop at MIT.
