....be sorted lexigraphically on the UCKs. Thus, when we say the data is sorted in this context, we mean that the data is sorted lexigraphically on multiple UCKs. Furthermore, for a merge to take place, both data sets must have similar lexigraphical ordering. Our experiments use grid data from NCAR [17] with multiple UCKs representing latitude, longitude and time. Notice that for grid data, # merges can provide meaningful approximations for certain applications. 4 Figure 1: CGM merge with tolerance # 4.1 CGM Algorithm In the CGM algorithm we assume the data is partially presorted. Without ....

The experimental setup was as follows. Data servers were located in Amsterdam and Chicago and connected via an OC 12 network. The merge was done on a separate machine in Chicago. The machine in Amsterdam was a dual P4, 1700 Mhz, with 512M RAM. ....
