Scalable Performance Analysis Tools for Petascale Computers

tele-TASK-recording of the speech

Performance analysis is a crucial step in program development for HPC systems. Due to the complexity of these architectures, optimizing program performance during the design process is impossible. Thus, programs go through a cyclic optimization process of performance bottleneck detection and program tuning. A severe limitation of most performance analysis tools used in this process is scalability. For machines, such as the Altix 4700 supercomputer installed at Leibniz Compute Centre in Munich with thousands of processors, and future petaflop systems this scalability problem has to be solved.

We will give an overview of the Periscope Automatic Performance Analysis Tool which is currently under development at Technische Universität München. Periscope searches performance bottlenecks during program execution. It consists of a set of distributed agents, each being responsible for a subset of the application´s processes. The agent´s search is based on a formal specification of performance properties in the APART specification language.
