Dear sir/madam,

Hello. I have installed the StarPU framework and I would like to execute the distributed cholesky version. However I am little bit confused with the command line arguments.

Actually, I would like to get strong scalability results, i.e. increase the number of nodes while the matrix size is the same.

So lets say that for the single node implementation the -size=8192 and the -nblocks=64, i.e. Matrix Size=8192x8192 and Tile Size=128x128

How should I configure the size and nblocks flags to have the same matrix size for 2 nodes and 4 nodes?

Thank you very much,
George Matheou
