Sending sampling mask to slave timed out

[Naxos]

Hello,
I have this error :

===== Error(-15) =====
Sending sampling mask to slaves timed out. Try to increase synchronization time or decrease maximum pixels per transfer.

What is it all about ? what settings are ok (default is 60s and 3000000 max pixels) ?

Rendersetup -> System -> Distributed Rendering.

But unless you do render a really big resolution on many slaves, or this error comes just sporadically, I would not change anything there.


Good Luck

Edit: Oh, I see your edit :) Just leave the defaults. How many slaves do you use and what resolution do you render? Usually there is no need for changing the defaults (60/3000000 methinks).

there are 24 nodes, and the picture resolution is 5000 x 3750.
In fact i'll let it render on half of it, because 12 nodes have only 24Gb in ram.

i've put it to 120s / 2000000 to give a test.

I understand the timeout, but can someone explain exactly what are the max pixels ?

[Frood]

The sync interval is actually no timeout, it's the average time period between transfers of results from slaves. 120s means, that in average, every 120s a fragment of the render result of a slave is sent to the master which can be 2000000 pixels large (a strip, 400px high in your case). I hope I got that right.


Good Luck

Many thanks.
