There hasn't been much time to write in the blog recently, STEP09 madness and all. However, it is wonderful to see that Glasgow was the top ATLAS T2 for analysis during the STEP09 challenges. We analysed more than 1.8B events, mostly through panda, with a 98% success rate.
We also took the largest fraction of data of any UK T2, 40%, and succeeded in getting all the data we were sent (we had little anxiety on the final weekend and want to increase our network heardroom for sure).
Sam and I wrote a full report on our experiences and how we used the opportunity to really probe the limits of the current cluster.
For the future, we really have to worry about how to maintain the i/o rate into the CPUs as the number of cores rises.
