Grid applications have demanding I/O needs. Schedulers must
bring jobs and data in close proximity in order to satisfy through-
put, scalability, and policy requirements. Most systems accom-
plish this by making either jobs or data mobile. We propose
a system that allows jobs and data to meet by binding exe-
cution and storage sites together into I/O communities which
then participate in the wide-area system. The relationships
between participants in a community may be expressed by the
ClassAd framework. Extensions to the framework allow com-
munity members to express indirect relations. We demonstrate
our implementation of I/O communities by improving the per-
formance of a key high-energy physics simulation on an inter-
national distributed system.
