Similarly, debugging becomes quite challenging because developers often have to reproduce the buggy thread schedules for diagnosis.  In this talk, I&#8217;ll present Peregrine, a compiler and runtime system we have built to simultaneously address these problems by memoizing schedules and reusing them on future inputs if possible.  Toward the end of my talk, I&#8217;ll briefly talk about how we are leveraging Peregrine to create a precise static analysis framework for multithreaded programs.<\/p>\n<\/div>\n<p><!-- .asset-content --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Multithreaded programs are difficult to write, analyze, test, and debug; a key reason is that different runs of a multithreaded program may show different behaviors, depending on how the threads interleave.
