Abstract : The results summarized in this document deal with the scheduling of independent tasks on large scale master-worker platforms, when realistic communication models are uti- lized. The contributions of this work are divided into three main parts: 1) Parallel algorithms: we underline the difficulty of scheduling identical independent tasks on heterogeneous master-worker platforms using the one-port communication model. We look at several sources of heterogeneity as well as several objective functions; 2) Matrix product: we compute the total communication volume that is needed for matrix multiplication in the presence of memory constraints and when data is centralized, and we develop a memory layout whose performance is close to the theoretical lower bound on the communication volume. We extend this algorithm for heterogeneous platforms; 3) Scheduling: lots of applications are constituted of a very large number of independent identical tasks. We focus on steady-state, and prove how to minimize the slowdown of one application when several are deployed, and how to minimize power consumption when only one application is present.
