In the 07-Cooling directory there are sequential source code to be optimized ( Fortran or C versions are equivalent, just choose the one you prefer ) and scripts for compiling and running on EURORA (with few changes on any other similar cluster). Tests have been realized with GNU compilers, but other C and Fortran compilers should do as well. The Xdots and Ydots parameters may be changed to 1000 in developing the optimised version, as well as reducing the "Computed steps" at the end of the 'Cooling.inp' input file, but the final tests and benchmarks should be carried out with the original values (1400 and 80 respectively). To check the correctness of the program, the values printed at all the steps by the original and the optimised program versions should match, although small differences could be acceptable. The generated image files could be assembled to create a video like FieldValues_c.avi, 10 frames/sec Would you please read the comments in the source code for further instructions
