graph - Getting non-unique results from METIS when different compiler is used -


i'm trying use metis 5.1.0 partitioning large graphs. have compiled metis source code in windows (using cygwin), linux (using gcc), , mac (using different version of gcc). unfortunately, results in various platforms different. tried 2 different versions of cygwin on windows , surprisingly affected results too. on other hand, using same binary on different machines (same platform) gives unique results.

i understand metis performs graph partitioning using heuristics compiler/platform dependency not acceptable in use case. have developed java application calls metis binary file , it's quite important me same result across various platforms.
