Hey Gang, I just noticed something peculiar on this topic.
I have attached an image, Left is Deadline, Right Hbatch on ‘manual mode’ =)
I noticed the frames that were already simulated were going back to 0k (file size) and then back again after a while.
I submitted the sim to one machine with ‘frames per task’ set to 300 frames. Did I forget anything or did I just bumped into a buggers?

PS: please ignore the file selection hilight on the image, its bullox. Notice the Modified dates… they go crazy with Deadline (left)
A lot of applications will create a placeholder file before they write their data (basically, fail fast if you can’t write anything instead of render for three hours only to hit an error saving the data). That’s my guess for the zero sized files. Maybe when within Houdini it can check to see if the folder has write permissions before starting? All just assumptions, no facts there.
As far as the modification dates, what am I looking for in the screenshots? The time seems to increment as I’d expect.
Thanks Edwin,
Looking at the modified dates on the left, you can notice that the dates are not in a sequence.
From what I could gather, once deadline reaches frame 5, frame 1 gets modified to 0k then back to its size.
This goes respectively for:
frame 6 / frame 2
frame 7 / frame 3
frame 8 / frame 4
This is what its not clear, if you reached frame 8 already, why does deadline need to modify frame 4?
Im using 2 machines, but they are assigned to different ranges. i.e Machine1 1-100, Machine2 101-200
The part on the right is using hbatch thru command line, submitting the same frames to the same machine. Can you see the dates there are in sequence, and also faster.
I dont really understand why the file size dont match exactly tho. That is not important, since it all seems to work.
For now I assume its the mesh compression that some how produces different results everytime.
If I’m honest, I’m not entirely sure about the sizes or the dates either. There’s nothing within Deadline that I’m aware of that should be a factor… If anyone else has any ideas, I’d be interested to hear them.
Update:
I should ask, are multiple Slaves rendering this simulation job? I assumed not, but I’m just covering bases here.
