Hi Kosta,


>> 
>> That sounds good to me. How many configurations are you planning for? It seems for gluon projects, 2-3k configurations would be required. 

You are absolutely right…I guess the following are 3 independent streams….

Best,

On the other hand we have allocations and we should start this analysis now. Performing the continuum extrapolation of the unpolarized PDFs is a good thing to do in the near future.
