Performance analysis tools for HPCPerformance analysis tools for HPC(what problems should the project address?)(what problems should the project address?)
• Most supercomputers have extremely low efficiency for a very wide range of applications.
• Most users have no information about their programs after submitting to a queue…
• “Low efficiency” can’t be explained by one reason, this is a complex problem…
• Sources of losses: policies and quotas of batch systems, RTSs, compilers, communications overheads, load imbalance, Amdahl’s law, a memory wall…
• There is neither a unified approach nor a software tool to detect sources of losses for users (for a particular task) and system administrators (for the whole supercomputer).
Performance analysis tools for HPCPerformance analysis tools for HPC(some key points of the project)(some key points of the project)
• Create an integrated environment that combines existing and new tools from the level of batch systems down to hardware monitors.
• Detect all sources of losses on the level of a particular task, a particular user, and the entire supercomputer.
• Collect, analyze, filter and display data in a scalable way up to exascale range systems.
• Analyze instrumented as well as non-instrumented tasks.
• Target architecture – clusters of SMP nodes with multicore processors and GPUs.
