It must generate Fortran77(90) + Message Passing code or possibly in one pass map HPF code onto parallel machine code
|
| 2 |
Traditional dataflow and dependency analysis is especially critical in Fortran77 parts of code
|
| 3 |
It must use data mapping assertions to decide what is stored where and so organize computation
|
| 4 |
Code must be transformed to respect this owner-computes model
|
| 5 |
It must typically use "Loosely Synchronous" model with communicate-compute phases and then compiler generates all the communication needed
-
Due to latency issues compiler must minimize communication needed and maximize size of packets sent
|
| 6 |
We need an excellent run-time library which the compiler invokes with parallel Intrinsics etc.
