Application Development & Compilers

HP UPC provides a simple shared memory model for parallel programming, allowing data to be shared or distributed among a number of communicating processors. Constructs are provided in the language to permit simple declaration of shared data, distribute shared data across threads, and synchronize access to shared data across threads. This model promises significantly easier coding of parallel applications and maximum performance across shared memory, distributed memory, and hybrid systems. The UPC language development clearly illustrates the growing trend away from implicit parallelism towards explicit parallelism.
