I tried with -mat_no_inode - no effect. Thats the output [1] MatAssemblyBegin_MPIAIJ(): Stash has 0 entries, uses 0 mallocs. [0] MatStashScatterBegin_Private(): No of messages: 1 [0] MatStashScatterBegin_Private(): Mesg_to: 1: size: 704692232 [0] MatAssemblyBegin_MPIAIJ(): Stash has 88086528 entries, uses 13 mallocs. [0] MatAssemblyEnd_SeqAIJ(): Matrix size: 553824 X 553824; storage space: 24984360 unneeded,19875384 used [0] MatAssemblyEnd_SeqAIJ(): Number of mallocs during MatSetValues() is 0 [0] MatAssemblyEnd_SeqAIJ(): Maximum nonzeros in any row is 42
