Resumen:
Abstract. Nowadays, many High Performance Computing (HPC) cen-ters with thousands of cores are available. The interconnection and syn-chronization between them is one of objectives of Grid Computing, as allthese centers tend to form a global shared computing facility. In such sce-nario, dynamics of resource information is increasingly complex, and maybecome almost impossible to be captured using a static hierarchy. One ofthe key features needed in Grid Computing is to maintain up-to-date in-formation about resources and services. Two important parameters thatmust be selected are the information refresh and expiration times. Inthis work, R is presented for studying the relation between these impor-tant parameters in three policies: Hierarchical, Super-peer and Random.The results reveal an interesting relation between expiration and refreshtimes in all studied policies. The study of this new parameter is essentialto provide a deeper knowledge in new information distribution policiesand in the configuration or deployment of existing ones.
