Hello everyone,

We recently purchased a dual AMD Epyk 7742 workstation to replace the old Threadripper 3970x one.

In Cinebench r20 the scores for the 2 machines are as follow:
1. Dual AMD EPYK machine - 32000
2. AMD Threadripper 3970x - 16000

Both systems are using Windows 11

However after initial testing with FLIP simulations the dual Epyk machine runs almost 2 times slower than the old Threadripper 3970x. We were expecting it to be 2 times faster, certainly NOT slower.

Does anyone have any suggestions as to why this is happening?

Thanks in advance,
Stefan

Does your geometry have groups for each piece? If you have primitive groups for each piece you could use this tool:

http://houdinitoolbox.com/houdini.php?asset=25 [houdinitoolbox.com]

It takes a geometry object and extracts each primitive group to a separate geometry container. Since it uses groups, if your source geometry is updated the updates should propagate to the extracted geometry unless group names are changing.

You could also use the Connectivity/Partition combination to generate a primitive group for each unique piece of geometry. If your input geometry changes however, there's no guarantee that the generated groups will be the same as they were before.

Does this tool still exist in the GitHub folder graham?

Thanks,
Stefan
