HKG15-402: Orphan hacking sessions --------------------------------------------------- Speaker: Dave Pigott Date: February 12, 2015 --------------------------------------------------- ★ Session Summary ★ One of the problems we experience quite a lot is to do with people setting inordinately long timeouts on their hacking sessions, which leaves the board unavailable for queued jobs. This session is to explore some of the possible solutions, in LAVA, the Lab and the general v.l.o community of users. Some possible scenarios are: - you have to specify in the job that if you leave the ssh session, you want to keep hacking up for later - if a hacking session detects that there are no users ssh’d in for a defined period of tim -------------------------------------------------- ★ Resources ★ Pathable: https://hkg15.pathable.com/meetings/250829 Video: https://www.youtube.com/watch?v=yY8bF9dGVn4 Etherpad: http://pad.linaro.org/p/hkg15-402 --------------------------------------------------- ★ Event Details ★ Linaro Connect Hong Kong 2015 - #HKG15 February 9-13th, 2015 Regal Airport Hotel Hong Kong Airport --------------------------------------------------- http://www.linaro.org http://connect.linaro.org
