The main classes of modern parallel computers Parallel Vector Systems (PVP)

Architecture
The main feature of PVP systems is the presence of special vector-conveyor processors, in which commands of the same type of processing independent data vectors are provided that are effectively executed on conveyor-based functional devices.

Examples

NEC SX-4 / SX-5, CRAY vector-conveyor computer line: from CRAY-1, CRAY J90 / T90, CRAY SV1, Fujitsu VPP.SX-5T90CRAY SV1VPP series

Scalability

As a rule, several such processors (1-16) work simultaneously on shared memory (similar to SMP) within multiprocessor configurations. Several such nodes can be combined using a switch (similar to MPP) .SMPMPP

Programming model

Effective programming implies vectorization of cycles (to achieve reasonable performance of a single processor) and their parallelization (for simultaneous loading of several processors by one application).
