Hello,
I have 2 questions about MatView.
1.I would like to ask if the process below is possible.
When running in parallel, is it possible to make the matrix of the mpiaij
format into a txt file, output it, and read it again so that the entire
process has the same matrix?
2.If
Hello,
I have some issues about different mode and different command.
1. Exactly the same code, but no error occurs in debug mode, but an error
occurs in opt mode.
In this case, what should I be suspicious of?
2. When executed with ./application, no error occurs, but when executed
with
Hello,
I have a question about rank of matrix.
At the problem
Au = b,
In my case, sometimes global matrix A is not full rank.
In this case, the global matrix A is more likely to be singular, and if it
becomes singular, the problem cannot be solved even in the case of the
direct solver.
I haven't
Hello,
There are some questions about some preconditioners.
The questions are from problem Au=b. The global matrix A has zero value
diagonal terms.
1. Which preconditioner is preferred for matrix A which has zero value
in diagonal terms?
The most frequently used basic 2 preconditioners
