Definition

• MPP refers to a computer system comprising several independent processors that run parallel to each other. These processors can work on different elements of the same program, while each uses its own memory and operating system.
  
  

Process

• MPP processors communicate by utilizing a messaging interface. Messaging is the exchange of messages, or specially formatted digital data used to describe replies, requests or various events, to a server. The arrangement, or interconnect, of data paths in the MPP system allows data messages to be transmitted between the processors. Some MPP systems may use up to 200 or more processors to work on a single program or application.
  
  

Fun Fact

• The earliest MPP systems used serial computers, or single-processor computers that execute one instruction at a time.
