v6: -bigadv
V7: client-type    bigadv
Sets a client preference to request extra large work units for multi-CPU socket class server systems. Â A minimum of 16 CPU cores is required for Assignment Server access, and to meet the extremely short deadlines. Â This is only a request for a specific type of work unit, and is never a guarantee the client will received this type of work unit. Â If none of these work units are available, and regular work unit will be downloaded instead.
In 2009, Dr. Kasson introduced a an experimental WU category called “bigadv”, intended for some of the most powerful computers participating in FAH. The initial core count requirement was 8 cores.  Currently, bigadv WUs require a minimum of 16 CPU cores and have very tight completion deadlines, although that minimum requirement has been known to change over time. These WUs have a high scientific priority, and are so computationally demanding they could not run anywhere else on Folding@home. They also consume much more RAM and Internet bandwidth, but in return a 20% increase in point value was added on top of the existing Quick Return Bonus points system.
Note:Â BigAdv work units are only available to Linux operating systems at this time. Â However, Windows availability may return in the future.
- July 2009 – Experimental BA program introduction, with 8 core minimum
- July 2011 – BA points curve adjusted downward, 50% to 20% target
- January 2011 – Core minimum raised to 16, deadlines shortened.
- May 2014 – Core minimum raised to 24, deadlines shortened.
- January 2015 – BA Experiment scheduled to end.
