Hi,
so we have been testing various combinations and suggestions from this thread.
Raising the interval does help with disconnecting nodes. But the overall speed is extremely poor.
These are the specs of the machines used:
x45 192.168.178.45:5401 PC, 40x2.3GHz, 64.00 GB RAM, (Studio Client) Windows 10, 64 Bit, Professional Edition (build 17763) Idle
x44 192.168.178.44:5401 PC, 40x2.3GHz, 64.00 GB RAM, (Studio Client) Windows 10, 64 Bit, Professional Edition (build 17763) Idle
x43 192.168.178.43:5401 PC, 40x2.3GHz, 64.00 GB RAM, (Studio Client) Windows 10, 64 Bit, Professional Edition (build 17763) Idle
x42 192.168.178.42:5401 PC, 40x2.3GHz, 64.00 GB RAM, (Studio Client) Windows 10, 64 Bit, Professional Edition (build 17763) Idle
x41 192.168.178.41:5401 PC, 40x2.3GHz, 64.00 GB RAM, (Studio Client) Windows 10, 64 Bit, Professional Edition (build 17763) Idle
ws35 192.168.178.35:5401 PC, 16x3.6GHz, 64.00 GB RAM, (Studio Client) Windows 10, 64 Bit, Professional Edition (build 17763) Idle
ws34 192.168.178.34:5401 PC, 32x3.8GHz, 64.00 GB RAM, (Studio Client) Windows 10, 64 Bit, Professional Edition (build 17763) Idle
ws32 192.168.178.32:5401 PC, 32x4GHz, 64.00 GB RAM, (Studio Client) Windows 10, 64 Bit, Professional Edition (build 17763) Idle
ws31 192.168.178.31:5401 PC, 64x3.8GHz, 128.00 GB RAM, (Studio Client) Windows 10, 64 Bit, Professional Edition (build 17763) Idle
We rendered the same 4000x4000px image with different variations
Rendering on the single 2990wx machine takes
14:34 using 8 machines from the list we got these results.The below tests were rendered from the PV with TR
30s/100mb most nodes disconnected
40/100 1 disconnected total render time stamped 14:26 (it took 6:20 to gather all the chunks and do the post process)
50/100 0,1 disconnected 14:07 (6:01)
60/100 no disconnected 15:54 (5:52)
90/100 no disconnected 19:57 (7:28)
using 5 machines
30/100 no disconnected 14:23
using 3 machines
30/100 no disconnected 15:41
With a packet size higher than 100 times got a lot slower at any interval. When disconnected this is the error we got:
"
Sending chunk 12/13 to the server
Frame synchronization failed: Communication Error"
also this one:
"019/02/08 14:45:42 [Corona4D] Sending chunk 2/5 to the server 2019/02/08 14:45:42 [Corona4D] MEMORY_ERROR while sending data 2019/02/08 14:45:42 [Corona4D] Frame synchronization failed: Memory Error"
with the above error the machine list would still show nodes rendering but the image wasnt updating and at over 20 mins nowhere near done
We also tried starting from the server app using the web interface.This time without the 2990wx. The remaining machines rendered the image in 14:55 The save path was set but the render wasnt save in that location at all.I was saved in the "results" folder. Th render is in liner color space and extremely different than any of the tests made so far
After this set of tests Im even more worried. It seems that for our network and number of nodes on this particular render the best combination was 50s/100mb as it rendered with 8 machines in 14:07 but compared to the 14:34 of the single 2990wx its very disappointing.
