PARALLEL PROGRAMMING IN

A visit to the neighborhood PC retail store provides ample proof that we are in the multi-core era. The key differentia-tor among manufacturers today is the number of cores that they pack onto a single chip. The clock frequency of commodity processors has reached its limit, however, and is likely to stay below 4 GHz for years to come. As a result, adding cores is not synonymous with increasing computational power. To take full advantage of the per-formance enhancements offered by the new multi-core hardware, a corresponding shift must take place in the software infrastructure – a shift to parallel computing
