Code generator for HPF library on Fujitsu VPP5000

The Fujitsu VPP5000 supports the data parallel language High Performance Fo rtran (HPF). The HPF Library gives a user access to intrinsic functions tha t are particularly useful in a data parallel environment. The implementatio n of HPF Library presents the challenge that all data types, all data kinds , all array ranks and all input distributions need to be supported. The num ber of specific functions runs into the billions so it is not feasible to c ode each individually. This paper presents a method to solve this problem. We have developed a library generator, which consists of templates and a te mplate processor along with an interface to the HPF compiler. We show that instead of implementing billions of specific functions, we only need to imp lement five templates.
