Abstract:
The modern supercomputer hardware strongly differs in principle from the 5–6-years old hardware. This is true both for the computational hardware and the communication one. The new, better communication hardware has some inherent advantages, that hardly can be properly expressed in terms of the traditional parallel programming technologies. The question of new parallel programming technologies, coming to replace the old ones, is discussed in the article.
Key words and phrases:supercomputer, programming model, parallel programming technology, dualsided transfer network, singlesided transfer network, cachecoherency, latency, aggregation.
