The plan defined by the CCC for the data processing was 1) to run in parallel for about a week, while RGK was a still in testing phase, 2) continue with RG-K alone until the 50% was reached, 3) continue in parallel till the end. It seems to me that we basically skipped 1 because the fairshare algorithm did what it is designed to do, we are in 2, and the natural thing would be to continue with 3.

As you mentioned the data processing has been progressing very well and, in about a week, we are already very closed to 50% of whole RG-K with the 7.5 GeV almost completed and the 6.5 GeV already started. At this pace, it looks like the 50% will be reached and exceeded over the weekend. <br>
<br>
During last week, the RG-B cooking, even if not fully stopped, progressed at a very slow rate because the farm fairshare algorithm favored the RG-K account that was not used in a while. Because of this, RG-K has been basically running alone for most of the time as for example it’s happening right now.<br>
<br>
Given this and considering the overall status, I think the 50% goal will be exceeded shortly, entering in what was defined as phase3 where both RG-K and RG-B can continue data processing in parallel. <br>
Best regards,<br>
Raffaella<br>
