Avoid concurrent startup of tasks when the client is started #1293

Open romw opened 9 years ago

romw commented 9 years ago

Reported by knreed on 10 Oct 43589063 08:56 UTC Some research projects use significant disk or other resources and concurrent start up of tasks can cause an impact on the system or possible result in heartbeat non-response. See http://www.worldcommunitygrid.org/forums/wcg/viewthread_thread,30688_offset,0#428458

It would be useful if the client would stagger the startup of tasks to avoid this issue or impact on the users machine.

Commented by Sekerob on 27 May 43596334 01:21 UTC Would propose for the tag to also work when coming out of hibernation. Staggered starts would be ideal as a second control. Certainly have found that if 8 CEP2 start at the same time, there's at least an hour passing of disk trashing before even 1 second of CPU time is logged, if system is left alone. From user perspective impossible.

vboxwrapper uses a random delay when started for exactly the same reason. One should add a random delay to starting apps in general especially when starting or coming out of hibernation.
