Description
Dear ALU developers,
We observe an increase of memory in our code using ALUgrid 3d in parallel. If we monitor the memory consumption of our time domain code, we observe that: -the memory increases only if we run the code on more than 1 core -the memory increase for rank=0 is 0 -the memory increase in ~128 kB steps -it occurs after an unpredictable number of timesteps -same behaviour for OpenMPI and MPICH2
We try to locate the function as good as possible and found in file: ALUGrid-1.14/src/duneinterface/gitter_dune_pll_impl.cc line 849: inner.first->EdgeData2os (sendBuff, edgeData , inner.second );
We tested it on Ubuntu 9.04 and 9.10 with the default gcc and OpenMPI and MPICH2 implementations.
It would be nice if somebody has an idea what's going wrong there.
Have a nice day Patrick
