There are assembly bits in valgrind, you could also look in libc and equivalents, also the other tools like strace, ld, etc. Compilers might have some parts in assembly (gcc, clang, etc). I don't know of any project that is largely in assembly - the only ones I know of are mainly C with some small bits in assembly. So could be a steep learning curve learning the intricacies of the thing in which the assembly is embedded (so to speak). Maybe also look for embedded type projects, or non-usual architectures. Maybe also libm, data science, graphics libraries - places where there are cpu-intensive operations that need optimization. What about the projects that run on graphics processors (boinc project or other distributed/crowd computing for example). Bitcoin mining (might run on dedicated ASICs). I would be interested to hear if you find something interesting to work on. bjb
