Abstract


The comprehensive analysis of algorithmic properties of well-known. Cholesky decomposition was performed on the basis of multifold AlgoWiki technologies. There was performed a detailed analysis of information graph, data structure, memory access profile, computation locality, scalability and other algorithm properties, that allow us to demonstrate a lot of unevident properties split up. into machine-independent and machine-dependent subsets. A comprehension of the parallel algorithm structure provide us with the possibility to efficiently implement the algorithm at hardware platform specified.
