6 The T9000 Farm

6.2 Porting of CPREAD to the T9000

The CPLEAR event reconstruction code (CPREAD) has been ported onto the T9000. The whole package contains 230,000 lines of Fortran'77 code. The AT&T Fortran-to-C (f2c) compiler was used to translate all Fortran into C due to the present lack of a Fortran compiler for the T9000. No optimization of CPREAD was performed during this step and only minor changes were imposed due to the use of f2c.

In addition, the CERN programming libraries, used by CPREAD, have also been ported to the T9000. These include 170,000 lines of Fortran and additional C code. These libraries include data structure, histogram and mathematics packages. This work demonstrates that other large physics Fortran applications may be ported onto the T9000.

A native Fortran compiler is currently being developed by ACE for the T9000, which should improve the performance of applications written in Fortran.
