SPO600 in Fall 2015
A new computer architecture has appeared: 64-bit ARM systems (also known as "ARM64" or "AArch64"). While AArch64 is showing up in cell phones and tablets, it is also poised to pounce on the datacentre. Most of the work of porting core software to AArch64 has been completed, and at this point, just about everything that runs on x86_64 Linux systems will run an AArch64 systems. However, the x86_64 architecture has been around for many years, and software has been well-optimized to work on that architecture; but AArch64 is new, and it may be possible to get better performance with additional tuning and optimization.
In Fall 2015, the SPO600 course will be focused on optimizing software on AArch64 systems, using the [ LEAP], [ Fedora], and [ CentOS] projects as a starting point. Specifically, we'll be analyzing the impact of various compiler options in the AArch64 context. We will build, benchmark, and profile specific software subsystems on with a wide range of compiler options and see if the assumptions inherited from the x86_64 computers, then do the same on AArch64, and identify areas for improvementworld are relevant. Then we'll experiment with compiler options, algorithm changes, and platform-specific code to optimize the performance.
Note that, unlike some other project-based courses, the results of the projects done in SPO600 will be incorporated into the actual "upstream" open source software, and have a real impact on other people. For this reason, projects must be completed in collaboration with the relevant open source communities, using relevant [[SPO600 Communication Tools|communication tools]]. Work performed in this course will be licensed using the relevant open source licenses used by the associated community.
