Compiling in a Persistent Distributed Shared Memory Environment

摘要

Plurix is a general purpose Operating System (OS) developed for the PC platform. Network communication is implemented by a Distributed Shared Memory (DSM). Restartable transactions and optimistic synchronization guarantee memory consistency. Making the DSM persistent allows us to abandon traditional file systems. The OS is developed using our own Plurix Java Compiler (PJC) translating source texts into machine instructions. PJC is an integral part of the OS and is used for program development. The persistent environment allows direct runtime structure generation. Symbol table entries are automatically registered by PJC in a cluster-wide name service and therewith survive the compilation process. After a short review of the persistent DSM environment we present integration aspects of PJC. Furthermore, we describe the implementation of our separate compilation scheme benefitting from the integration of OS and compiler. Finally, we present measurement results.
