Using the eNANOS Low-Level Support in the GRMS Framework

The eNANOS is an execution framework developed in the Barcelona Supercomputing Center. One of its main objectives is to provide a framework to execute multilevel parallel applications with low-level support. It is also able to provide information about the execution behavior of applications in run time. This information can be used by a Grid Resource Broker or metascheduler to improve its scheduling and resource strategies and the execution platform can improve the execution time of applications and resource usage as well. In this paper we discus the steps that we have to follow to integrate the eNANOS execution environment into the GRMS infrastructure, developed by PSNC. In particular we are interested in the mechanisms to allow the integration of the different components and how to use the information provided by eNANOS to improve the scheduling strategies in the GRMS system.
