[petsc-users] memory crash with optimized petsc

[Fande Kong]

Hi all,

I can correctly run my application based on the petsc ( --with-debugging =
yes). But the same code encounters memory crash when it runs with optimized
version ( --with-debugging = no) . The detailed information for errors and
results is attached. The logs for configure and make are also attached.


Now, there are several questions I want to know.

(1) What are differences between debug version and optimized version in
terms of memory management and communication?

(2) I print some memory usages. Why does the optimized version cost twice
more memory than the debug version?

(3) How to debug the optimized code to fix memory issue?

Regards,
