Abstract
We are developing a program called GeoFEM, which is a parallel programming platform for the solid earth analysis and the program is intended to use on “Earth Simulator” which is promoted by Science and Technology Agency, Japan. For GeoFEM, many parallel analyzing programs have been developed and will be developed, but the input data format of these programs must be common in a sense. For this purpose, 1) the specification of data which is commonly used by the analyzers of GeoFEM is fixed, and 2) GeoFEM Data description Language (GDL) is provided for supporting of uncommon data items among analyzers. The data specification written in GDL is automatically converted to the “reader” program for the data which conforms to the defined specification. In this paper, these two techniques are described and the comparisons with the other data services, netCDF, HDF5, and CORBA externalization service are made.
