Peregrine: Help for programming concurrency

Good news from Columbia University. Peregrine is automated software to aid in programming concurrency. More in the ACM: Major Breakthrough Improves Software Reliability and Security:

"Our main finding in developing Peregrine is that we can make threads deterministic in an efficient and stable way: Peregrine can compute a plan for allowing when and where a thread can 'change lanes' and can then place barriers between the lanes, allowing threads to change lanes only at fixed locations, following a fixed order," says Columbia professor Junfeng Yang. "Once Peregrine computes a good plan without collisions for one group of threads, it can reuse the plan on subsequent groups to avoid the cost of computing a new plan for each new group."
