Services for modeling metasystem performance using queuing network models

The use of metacomputing systems for high performance computing is gaining considerable acceptance. In such kind of environments, performance models help to obtain the expected application performance. Hence, it is important that the metasystem provides services for building these models. These services should support the main activities related to model development: measurements to parameterize the model, and the possibility of reproducing scenarios, which is useful for calibration and validation tasks. Our research focuses on identifying these services and incorporating them into the SUMA metasystem. In this article, we describe the identified services and how they are going to be included in SUMA. The obtained parameters will feed queueing network models (QNM). Additionally, we describe the service that measures the metasystem overhead and show some preliminary results.
