Hello! I'm currently investigating both of these features you have mentioned, specifically on the NEAT[1] and GANTT[2] projects, as you might see on the last week discussion.
Do you have any further ideas about how and why this would work with Heat? Thanks, Henrique [1] http://openstack-neat.org/ [2] https://github.com/openstack/gantt 2014-04-13 22:53 GMT-03:00 Jiangying (Jenny) <jenny.jiangy...@huawei.com>: > Hi, > > there has been a heated discussion about dynamic scheduling last week.( > http://www.mail-archive.com/openstack-dev@lists.openstack.org/msg21644.html > ) > > I am also interested in this topic.
