Lark
Introduction
Lark is a NSF-funded project for adding network-awareness to Condor's High Throughput Computing approach.
Broadly, it can be split into three major areas:
- Advanced Network Testbed: A small testbed for Condor networking technologies. Consists of dedicated Condor pools at Wisconsin and Nebraska. This will serve as a "launch point" for Lark technologies onto the production clusters at the sites.
- Network Monitoring: Integrating existing network monitoring tools (particularly, perfSONAR) into the Condor ecosystem. This will provide various Condor daemons with the ability to make decisions based on the observed network state.
- Network Management: Have Condor actively alter the network layer based on its internal policies.
Lark started on October 1 and will last for approximately two years. More information will be added to this wiki page as the project progresses.
Advanced Network Testbed (ANT)
The ANT consists of small Condor pools at Nebraska and Wisconsin. These are meant to test Lark technologies and harden existing advanced Condor network technologies.
Example ANT use cases include:
- Verification of IPv6 support, especially of the flocking use case.
- Testing of network accounting at several sites.
- Testing dynamic VLAN creation between Nebraska and UW.
