Earlier this morning, I gave a presentation at the 2015 OpenFabrics Software Developers’ Workshop. I discussed Cisco’s experiences with writing providers for both the Linux Verbs API and the Libfabric API.
Here’s a copy of my slides:
The main takeaway from my presentation is that the libfabric APIs make more sense on our hardware than the Linux Verbs APIs. The slides elucidate several specific cases where — mainly because Libfabric was specifically designed to be much more hardware-neutral — Cisco VIC and Ethernet-based abstractions can be exposed naturally through the libfabric APIs.
