With synchronous iterations, the number of iterations is exactly the same than in the sequential mode (if the parallelization process does not change the algorithm). So the difficulty with - asynchronous iteratie algorithms comes from the fact it is necessary to run the algorithm + asynchronous iterative algorithms comes from the fact it is necessary to run the algorithm with real data. In fact, from an execution to another the order of messages will change and the number of iterations to reach the convergence will also change. According to all the parameters of the platform (number of nodes, power of - nodes, inter and intra clusrters bandwith and latency, ....) and of the - algorithm (number of splitting with the multisplitting algorithm), the - multisplitting code will obtain the solution more or less quickly.

Of course, the GMRES method also depends of the same parameters.
