Micromanaging CPU vs GPU Workunit Limits
Hey Everyone,

I will be tweaking some config options on the server to better improve database stability and allow for stockpiling of more workunits by GPU users.

The new workunit limits should be as follows:
Separation:
600 total
200 GPU (Per GPU up to 600)
40 CPU (Per CPU up to 600)
Nbody:
120 total
20 CPU (Per CPU up to 120)


Hopefully you guys notice this on your end. If we notice we are running out of workunits more frequently on the server, I will increase the workunit cache a bit.

Let me know what you all think about these numbers and how it is working for you.

Database Maintenance 12-18-2018 - Beginning
Sorry for the delay to the posting. There was an issue on the server before the maintenance window. This delayed this posting. The database is going down for a brief period. I will post a message when the server is operational.

Nbody release 1.72 soon
I will be releasing a new version of the Nbody application within the next 24 hours. Its a minor change to our cost function, but an important one. Hopefully this version will converge to optimized values faster!

As always,
thank you for your continued support,
