The Good News -- In 1993, NPAC selected to Partner with two Grand Challenge Groups as part of their "computer science" support
|
|
Both Applications were rather suitable for HPF as regular grids
|
The Bad News -- Both Application groups have abandoned HPF as couldn't wait for working compilers with appropriate features
-
But BOTH have switched to using Fortran90!!
|
Numerical Relativity needed adaptive mesh and this supplied by DAGH from Texas which is like HPF but simpler in overall capability but can handle adaptive meshes
-
But need to wait for new features in DAGH to handle say conjugate gradient which is automatic in HPF
-
Need to parallelize sophisticated data types (tensors) in Fortran90

|
In Data Assimilation, a NASA Goddard application, they are recoding in Fortran90 plus MPI as MUST meet specific performance goals in a year
