This paper argues the widespread adoption of Just-in-Time (JIT) logistics provides a key to understanding the growth in the U.S. trade share. To do so, I develop a dynamic trade model based on the choice of the logistics technology used in a firm’s supply chain. The model’s predicted trade dynamics depend on how the set of firms using JIT with international suppliers changes over time. A numeri...

Fortran D is a version of Fortran extended with data decomposition speciications. It is designed to provide a machine-independent programming model for data-parallel applications and has heavily innuenced the design of High Performance Fortran (HPF). In previous work we described Fortran D compilation algorithms for individual procedures. This paper presents an interprocedural approach to analy...

We describe how various sparse matrix and distribution formats can be handled using the relational approach to sparse matrix code compilation. This approach allows for the development of compilation techniques that are independent of the storage formats by viewing the data structures as relations and abstracting the implementation details as access methods.
