Abstract: Performance profiling tools are crucial for HPC specialists to identify performance bottlenecks in parallel codes at various levels of granularity (i.e., across nodes, ranks, and threads).

Add a description, image, and links to the python-beginners-game-file-io topic page so that developers can more easily learn about it.

Written originally to see if file I/O in CodeHS.com works with their version of Python 3.8.18 (it doesn't).

Abstract: Modern data storage systems often fetch data from a large number of sources. Although synchronous data transfer is simple as it can use simple scheduling of data delivery, it scales poorly.
