Hi all,<div><br></div><div>How to measure the memory usage of the application built on the Petsc? I am now solving linear elasticity equations with fgmres preconditioned by two-level method, that is, preconditioned by multigrid method where on each level the additive Schwarz method is adopted. More than 1000 cores are adopted to solve this problem on the supercomputer. When the total freedom of the problem is about 60M, the application correctly run and produce correct results. But when the total freedom increases to 600M, the application abort and say there is not enough memory ( the system administrator of the supercomputer told me that my application run out memory).</div>
<div><br></div><div>Thus, I want to monitor the memory usage dynamically when the application running. Are there any functions or strategies that could be used for this purpose?</div><div><br></div><div>The error information is attached.</div>
