Abstract:   The number of processor cores available in high-performance computing systems is steadily increasing. In the November 2011 list of the TOP500 supercomputers, only a single system has less than 2000 processor cores and the average is almost 18,000 cores, which is an increase of 5.000 in just one year. While these machines promise ever more compute power and memory capacity to tackle today's complex simulation problems, they force application developers to greatly enhance the scalability of their codes to be able to exploit it. To better support them in their porting and tuning process, many parallel tools research groups have already started to work on scaling their methods, techniques and tools to extreme processor counts. In this tutorial, we survey existing performance analysis and optimization tool covering both profiling and tracing techniques, demonstrate selected tools, report on our experience in using them in extreme scaling environments, review existing working and promising new methods and techniques, and discuss strategies for addressing unsolved issues and problems.
