  1. Performance Evaluation of Large-Scale Scientific Applications on Grid Computing Environments with PRIME By Miguel A. Erazo Advisor: Jason Liu March 2009

  2. PRIME network simulator

  3. PRIME cont.

  4. Previous mid-size experiment • Simulated – emulated hundreds of nodes • Tested real applications performance in presence of background traffic

  5. Previous work • In previous work we built a platform to evaluate TCP variants • We showed that PRIME accurately models real applications and TCP behavior

  6. Our objective • Develop a large-scale Grid application performance evaluation platform based on PRIME • PRIME will be augmented with the ability to model various specific networking resources in global Grid environments

  7. Our objectives cont. • We will extend the performance evaluation platform to predict the power signatures of large-scale Grid applications

  8. Proposed approach • Number of distributed sites, each simulating a portion of network • Real and simulated traffic are integrated • A single site may consist of a cluster of parallel computers • We map the sub-model to the available machines
