-RAISA is a data analytics model for in-situ and in-transit workflows based Ray, a Python framework providing a distributed execution model.
+REISA is a data analytics model for in-situ and in-transit workflows based Ray, a Python framework providing a distributed execution model.
 
-RAISA exposes a distributed task-based paradigm for in-situ o in-transit analytics coupled to MPI numerical simulations at scale.
+REISA exposes a distributed task-based paradigm for online analytics coupled to MPI numerical simulations at scale. The coupling and communication between Ray and the simmulation is managed by PDI, a portable data interface that offers a declarative API to decouple application codes from I/O. Therefore, just adding some simple PDI command to the numerical simulation and writing a simple analysis kernel we can get an online distributed analysis at scale for the data stream generated by the simulation.
