Most of theprocessor manufacturers such as Intel and AMD are following more conventional approaches which consist of homogeneous symmetric multicores whereexecution units are replicated on the same dime; multiple execution units sharesome cache level (generally L2 and L3) and the bus to memory. Other manufacturers proposed still homogeneous approaches but with a stronger emphasis onparallelism and hyperthreading. This is for example the case of Sun with theUltraSPARC T1 (known as Niagara). The UltraSPARC T1 2524] can haveup to eight homogeneous cores each of which is fourway hyperthreaded whichdelivers a maximum parallelism degree of thirtytwo. The Niagara processor ismostly developed for web servers and database applications since it provideshigh computational power for integer operations which are used considerably inpointer arithmetics and string processing. Yet other chip manufacturers startedexploring heterogeneous designs where cores have different architectural features.One such e ...
