[Trilinos-Users] VbrMatrix RAM usage

[Andrea Zonca]

hi,
I have some issues with understanding VbrMatrix ram usage;
I created a test case where I create a Block Matrix where each processor has
500 000 blocks, each 1 row by 3 columns doubles.
The total data is about 5 MB per processor.
However when I effectively build the matrix, I notice ram consumption
of about 56 MB
per processor.
Is this reasonable or am I doing something wrong?
Working test case here (with RAM usage report at different stages):
