Run 01 (VALM01): Winter 2017 Berlin, Jan 17 06:00 UTC - Jan 18 06:00

Status message: debugging

Description Date of issue Closing date Further remarks
Start of VALM01 testing 01/01/2019
... ...
Crash in nested runs. April-May ... Smaller test simulations run well.
Memory demand for calculation of view factors (radiative transfer) 01/08/2019 03/08/2019 OOM killer aborted processes randomly. Using not all cores on node fixed this.
Parent and child grids do not overlap (required after revision of the nesting) 05/08/2019 05/08/2019 New child drivers are required as number of grid points changed.
Driver problem with bridges at the boundary. 05/08/2019 05/08/2019 Child was moved a few meter northward.
Bug in building parameters, wrong dimension in static input file 08/08/2019 08/08/2019
Bug when green roofs are present. 09/08/2019 10/10/2019 Green roofs where disabled in the simulation. Fixed now.
MPI network problems on the cray machine in Berlin 10/08/2019 19/8/2019 Recurring MPI failures at different locations in the code, appeared only in the large winter IOP simulations, not in smaller ones. As a consequence, all runs were carried-out on the Atos machine in Göttingen.
Minor bug in new implementation of external radiative forcing 21/08/2019 21/08/2019
Failure due to MPI errors. 05/09/2019 21/09/2019 Appeared also in smaller test simulations. Need to be fixed on HLRN side.
Emission module caused model crash 23/09/2019 27/09/2019
MPI error just at the beginning of the run - HLRN internal problem: ofi fabric is not available ... 24/09/2019 ? Error does not appear any more.
Crashed with error message corrupted double-linked list 01/10/2019 07/10/2019 Seems that scheduling is not working properly, had been queued for 4 days!!! Further debug messages implemented to narrow down the location. Message comes from the parent domain. However, memory consuming sky-view factors were calculated.
Crashed with An allocatable array is already allocated 09/10/2019 10/10/2019
Crashed by an MPI error 13/10/2019 Parent finished initialization. Crashes in a MPI_ALLGATHER call in surface_data_output_init. Might be connected to the HLRN-network problem (14/10/2019).
Crashed again with error message corrupted double-linked list in child simulation. 17/10/2019 Parent finished initialization. Crashes again in surface_data_output_init. Next step: switch-off surface-data output as this has no priority at the moment.

(note that the list of past bugfixes will be updated soon)
