Please see Dr. Pande's announcement - https://folding.stanford.edu/home/big-a ... anuary-31/ and Dr. Kasson's recent posts here. Based on those:

There are no more BA WU's being assigned.

Any assigned before the cutoff on January 31 will be accepted for return.

There are large WU projects in the process of being released that will use Core_A5, the points awarded are going to be based on the same benchmarking as existing SMP CPU projects.

Your last question seems to be confusing terminology about the available clients. Both the version 6 and 7 clients can be run using a GUI, or they can be run from the command line.

so ... what would be the GUI "configuration" to get these "high core count" work units ? ... something like ... client-type / advanced or CPU / BigAdv
or what?
also how would i know when they are available? and if there are a restrictions like ... no 31 core clients
sorry for my ignorance i havent been on the forums for a LONG time

Same as before. No change from BA settings to get the new large core count work units.

See this post from Dr. Kasson about the bigadv setting will get assigned to appropriate WU's - viewtopic.php?f=55&t=27312&p=273478#p273478.

There is an existing bug in version 6 that will occasionally result in it not getting assignments. Deleting the machineindependent.dat file as mentioned in this topic - viewtopic.php?f=55&t=27319 - will work around that bug.

Announcements will be posted in the PG announcement area or the Beta forum, such as these announcements - viewtopic.php?f=66&t=27322&p=273502#p273502 & viewtopic.php?f=24&t=14714&p=273501#p273501.

As for core counts, the limitations stay the same as they have been. "Large primes" and multiples of them will not be used. Basically any prime starting with 11 on up has been found to cause problems and are not used. Often the wrapper included with the WU will take care of moving the usage to a "safe" number, you will see a message in the log such as "Mapping NT from 31 to 30". Occasionally 7 and its multiples have been problematic as well. Beyond that, a number of larger odd numbers are also disallowed, but again usually the core will map to an allowable number of cores.
