Backburner can't communicate with simming node during sim?

[bdemetz]

This may be by design or limitation, but generates a problem as follows:

We have backburner go down often. Since there seems to be no communication between bb and the simming machine once simming starts and until it's finished, when backburner is restarted, it thinks that the sim job has been reset (even tho the simming node is happily still simming away), so bb sends the job to another machine and the sim starts over on a 2nd node.

Any workarounds?

This is also troublesome because if you've sent off a bunch of sims, you can't stop them within bb. You have to go cancel the sim on each node that's simming.

Thanks,

Well I think all of that is correct, although I wonder why your BB manager(I'm guessing that's what you ment) gets restarted very often.
Does it do it by itself or do you restart the mashine.
I mean that is basically the solution for your first problem - down here the bb manager wasn't down for about 4 months now, and that's just because we had an upgrade then

The simulation process on the node is considered a single frame render job by BB so there is no way of interrupting it using BB.

You could and probably should ask your software department to write a program (like a trojan) to control your rendering nodes. That would basically let you restart bbservers, frservers (if your using FinalRender), and ultimately the system itself if the above don't work
We did it here and we honestly could not go down to the "engine room" for a month

our bb manager goes down about once every couple days and it will either restart automatically or we have to restart it. basically happens when we load it down with a ton of render jobs.

it's something we will not be able to avoid, especially if we need to restart the bb manager machine.

bb restarting issues aside, it also seems that a single sim job will be submitted to different servers at the same time - as if bb doesn't flag that it's already submitted it. anyone else having issues like this with regard to bb simming?

Thx again,
