After adding this test in petsc4py-dev/test/test_ksp.py :

def testResetAndSolve(self): self.ksp.reset() self.testSolve() self.ksp.reset() self.testSolve() self.ksp.reset()

it seems there is some memory bleeding:

[0]Total space allocated 256 bytes [ 0]80 bytes KSPSetUp_BCGSL() line 476 in /home/devel/petsc/dev/src/ksp/ksp/impls/bcgsl/bcgsl.c [0] KSPSetUp() line 184 in /home/devel/petsc/dev/src/ksp/ksp/interface/itfunc.c [0] KSPSolve() line 332 in /home/devel/petsc/dev/src/ksp/ksp/interface/itfunc.c

These are workspace arrays that are re-allocated at every KSPSetup_BCGSL call.

Not sure about the proper way to fix this, but I would deallocate the arrays at KSPReset_BCGSL. Can anyone help me with this?

PS: Will we ever have petsc4py in the nightly builds? Is there something to be done from my side?

Sorry - will check on adding one.. Satish
