record interesting papers that I (partially) read

I will present DAMON/DAMOS in KernelSummit'21. The title of the talk is “Writing a fine-grained access pattern-oriented lightweight kernel module using DAMON/DAMOS in 10 minutes”. https://linuxplumbersconf.org/event/11/contributions/984/

This post is for recording some notes from a few OSDI'21 papers that I got fun. DMon: Efficient Detection and Correction of Data Locality Problems Using Selective Profiling https://www.usenix.org/system/files/osdi21-khan.pdf DMon is a compiler-based data locality optimization system. The approach is quite similar to that of daphicx or similar things. It injects data access profiling code in the target program, build and run it with some workload, collect the profiling code-generated results, analyze the profile results to figure out what kind of optimization can provide some benefit to the program, injects the optimization code in the program, built it again, and deploy the version to the production....

I stopped translation of perfbook since 2019-09-27. Because the 2nd edition of perfbook is released[0], I’m starting the translation again[1], from the scratch. The old versions are still available, of course[2].
