[petsc-users] memory control

[Zhang Wei]

Hi
I am new to the slepc, I am struggling with handson exercies "Exercise 5: Problem without Explicit Matrix Storage", it seems the memory cost is really big for the case, as i simply increase the size of case ,n, to 9600 resulting cost around 8Gb memory during the runtime, and at beginning stage, it is clearly observed that each vector in krylove space cost 800Mb for 9600 elements case.. that is unreasonable.can any one help me on that ?
