Using fgmres to solve large-scale linear equation systems

houjy — Sun, 01 Sep 2024 13:04:01 GMT

I have used ILP64 successfully.

But I have another question,When I use fgmres to solve large systems of linear equations, some values in the ipar array are equal to -5589219598436180572

Thank you very much

Hi,

Thank you for your questions. Could you please provide me more details on this? You can provide your configuration setup which might be one of the reason you are getting this error. Or else your example code that you're trying to run.

This is my code example. I would like to try solving a system of linear equations with a scale of 69335390 or above. Thank you very much.
