SMP
SMP (Symmetric Multiprocessing) - computer architecture in which within a single instance of operating system there are more than one processor. Nowadays almost every modern computer is built based on this architecture, for example by integrating multiple cores in a single processor.
For computer systems the name 'SMP' is commonly used to describe supercomputer containing from ten to even a few hundred processors in a single instance of the operating system. Usually such systems have a very large amout of RAM, which, thanks to the SMP architecture, is shared by all cores of the system. By this solution it is possible to run applications using eg. threads (OpenMP) for computations parallelization or processing very large data sets directly in memory, what significantly boosts computations.
In Cyfronet the SMP architecture is used in the two systems currently:
