{section: Lark} {subsection: Introduction} -Lark is a NSF-funded project for adding network-awareness to HTCondor's High Throughput Computing approach. +Lark was a NSF-funded project for adding network-awareness to HTCondor's High Throughput Computing approach. Broadly, it can be split into three major areas: *: Advanced Network Testbed: A small testbed for HTCondor networking technologies. Consists of dedicated HTCondor 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 HTCondor ecosystem. This will provide various HTCondor daemons with the ability to make decisions based on the observed network state. *: Network Management: Have HTCondor 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. +{subsection: Results and Products Produced} +Work on Lark started on Yr 2013 and completed in Yr 2015. + +Read about more about Lark results via published research papers, such as + +*: Zhe Zhang, Brian Bockelman, Dale Carder, and Todd Tannenbaum, +"Lark: Bringing Network Awareness to High Throughput Computing", Proceedings of the 15th IEEE/ACM International Symposium on Cluster, Cloud and Grid Computing (CCGrid 2015), Shenzhen, Guangdong, China, May 2015. [ {link: https://research.cs.wisc.edu/htcondor/doc/lark-ccgrid2015.pdf PDF version} ] + +Lark produced {link: http://is.gd/p30kCd code for a pluggable HTCondor contrib module}, with plans to merge much of this code (currently on git branch V8_2-lark-branch) into production HTCondor during the v8.5 or v8.7 developer series. + {subsection: Advanced Network Testbed (ANT)} The ANT consists of small HTCondor pools at Nebraska and Wisconsin. These are meant to test Lark technologies and harden existing advanced HTCondor network technologies.
