Language and Input-Output for Large-Scale Parallel Computing
Programs for scientific and engineering calculations are swelling beyond the program productivity of academic researchers. One of the main reasons is that the burden of the control of data transfer between the main memory and external memories is left with programmers. A sample program, which would be written in just several tens of lines if it could be performed with the main memory, expands by as much as fifty times when plural kinds of memories must be used. This paper gives a proposition to overcome this problem by introducing a new high-level language supported by an input/output architecture. The new language is a modified version of PARAGRAM, which is a program language for parallel processing.
