Extending Modulo Scheduling with Memory Reference Merging
[chapter]
1999
Lecture Notes in Computer Science
Preserved Fulltext
Experiments on the Cray T3E demonstrate the benefits of memory reference merging. ...
This technique has been used over several years on the Cray T3E block scheduler, and was later generalized to the Cray T3E software pipeliner. ...
Currently, software prefetching on the Cray T3E is limited to library routines that were developed and optimized in assembly code. ...

Acknowledgments Keith Farkas provided helpful comments on a draft of this retrospective as well as insightful work on stream buffer enhancements. ...
The Cray T3D and T3E also used stream buffers on the data side, as a replacement for a secondary cache. ...
As a result of this study allocation filters were implemented in the Cray T3E. More recently, stream buffers have been studied in the context of more modern processor designs. ...

The type qualifier declaration supports an abstract shared memory facility on distributed memory machines while making direct use of hardware support on shared memory architectures. ...
Although the resulting shared memory programming model is portable, it does not remove the need to arrange for overlapped or blocked remote memory references on platforms that require these tuning measures ...
