GPI is a new interface for application development for multicore architectures. GPI stands for Global Address Space Programming Interface, it implements the PGAS (Partitioned Global Address Space) programming model.
The advantages of GPI are the communication performance at wire speed and its scalability on multicore systems. Several benchmarks demonstrate the excellent scalability of GPI, also in cases where MPI scales poorly.
GPI directly extends the simple threadbased programming model from the node level to the cluster level. GPI works with Posix threads or with the optimized hardwareaware multicore thread package MCTP.
GPI handles all communication asynchronously without interrupting
