Current and emerging shared memory hardware Multicore systems: two or more cores, incomplete CPUs that share some resources Simultaneous multithreading: one core (CPU) executes instructions from two or more threads, or instruction streams to better exploit functional units in hardware SMP: two or more full processors, possibly combined with multicore and/or simultaneous multithreading May be combined with one or more “accelerators” SMP: symmetric multiprocessor or shared memory parallel system
