A collection of specialized threads in a user program that the compiler creates to execute a section of code in parallel on a single processor. A fray is similar to a crew, except that a crew executes on multiple processors. Unlike other threads, these compiler-defined threads spin-wait on memory references rather than suspend-wait. The most common reason that the compiler creates a fray or a crew is to distribute iterations of a loop among several threads that execute concurrently.
