Q. Illustration of parallel programming environments?

Let's discuss illustrations of parallel programming environments of Intel paragaon XP/S and Cray Y-MP software.

The Cray Y-MP system operates with UNICOS operating system.  It has 2 FORTRAN compilers CFT and CFT 77 for automatic vector code generation. The system software has huge library of routines, debugging aids, program management utilities as well as assembler UNICOS which is written in C. It supports vectorizing, optimizing, concurrentising facilities for FORTRAN compilers as well as has vetorizing and optimizing C compiler.  The Cray Y-MP has three multitasking/multiprocessing methods namely (i) Macrotasking, (ii) microtasking, (iii) autotasking. It has a subroutine library comprising numerous utilities, high performance subroutines along with scientific and math routines. 

The Intel Paragaon XP/S system is extension of Intel iPSC/860 as well as Delta systems and it is a scalable in addition mesh connected multicompiler that is applied in distributed memory system.

The processors which for nodes of system are 50 MHz i860 XP Processors. In addition it uses distributed UNIX based OS technology. The languages supported by Paragaon comprise C, C++, ADA and Data Parallel Fortran. The tools for integration involve FORGE and Cast parallelisation tools. The programming environment involves an Interactive Parallel Debugger (IPD).
