Hi,
Have you tried the new MILU0Preconditioner?
Seems like this might be a good use case for a sparse implementation of direct factorizations (LU, QR). Unfortunately these direct factorizations do not leverage sparse datastructures at all yet, making them very slow in practice on sparse data.
Concerning the out of memory, are you running the process as x64 with gcAllowVeryLargeObjects enabled?
Thanks,
Christoph
