8.9 Common User Environment The CUE working group continues to work toward releasing the CUE to the Teragrid User Community. The group wrapped up the beta testing period and is working with TG Public Relations team to announce the development. The CUE implements and procedures have been finalized on all current TG architectures, and documentation has been created explaining its use. The group also continues to work on how to improve the commonality of queuing and testing throughout the TG. 8.10 System Performance Metrics 8.10.1 Resource Usage Summary TeraGrid saw a slight dip in delivered NUs for Q4 2010. TeraGrid compute resources delivered 13.2 billion NUs to users, down 0.2 billion, or 1%, from Q3 ( Figure 8-7). However, the 13.2 billion NUs represent a 1.7x increase in the NUs delivered in Q4 2009. Nearly 100% of those NUs were delivered to allocated users. Figure 8-7. TeraGrid Computational Resource Usage 8.10.2 Summary of Usage / Users / Allocations by Discipline Figure 8-9 shows the relative fraction of PIs, current accounts, active users (individuals charging jobs), allocations, and NUs used according to discipline. The nine disciplines with more than 2% of NUs used are listed in the figure. Staff project usage is excluded, and users that appear on more than one allocated project may be counted more than once, if those projects are associated with different fields of science. Consistent with past quarters, the same disciplines dominant the NUs used column, though there have been some changes in the ordering. As in past quarters, more than 20% of PIs and current accounts, as well as 15% of active users, are associated with the 19 “other” disciplines, collectively representing about 4% of total quarterly usage. 86
Figure 8-8. TeraGrid Usage Summary by Discipline 8.10.3 Summary of Top PIs / Projects, Overall and by Discipline 873 different projects charged usage on TeraGrid computational resources, down just slightly from 882 in Q3 2010. Figure 8-11 shows the top 20 PIs by total usage in NUs. The top 20 PIs consumed 51% of the NUs used and the remaining 853 projects consumed the other 49%. Table 8-1 shows the top PIs (>2% of the discipline’s usage) in each discipline with more than 2% of total usage; the final section shows the top PIs for all other disciplines. The overall rank of each PI among the 873 projects charged is also listed. 87
