Up: Compilation Strategies for HPJava
Currently, the HPJava translator has two phases, pre-translation
and translation. Pre-translation reduces the source HPJava
program to an equivalent program in a restricted form of the
full HPJava language. The translation phase transforms the pre-translated
program to a standard Java program.
The main reason the current HPJava translator has two phases is to
make the basic translation scheme simple and clear, by transforming
certain complex expressions involving multiarrays into simple
expressions in the pre-translation phase.
Thus, the restricted form generated by the pre-translator should be
suitable for being processed in the translation phase.
Unlike with HPF, the HPJava translation scheme does
not require insertion of compiler-generated communications, making it
The current translation schemes is documented in detail in the HPJava
manual, called Parallel Programming in HPJava , and
also in the paper .
