OdinMP/CCp -- a portable implementation of OpenMP for C We describe here the design and performance of OdinMP/CCp, which is a portable compiler for C-programs using the OpenMP directives for parallel processing with shared memory. OdinMP/CCp was written in Java for portability reasons and takes a C-program with OpenMP directives and produces a C-program for POSIX threads.par We describe some of the ideas behind the design of OdinMP/CCp and show some performanceresults achieved on an SGI Origin 2000 and a Sun E10000. Speedup measurements relative to a sequential version of the test programs show that OpenMP programs using OdinMP/CCp exhibit excellent performance on the Sun E10000 and reasonable performance on the Origin 2000.
