5 years 2 months Adding CMake scritps for finding PETSc. In any case the environment variables PETSC_DIR and PETSC_ARCH need to be set!
Commit 150, by Thomas Egger
5 years 2 months Reverting changes made to ViewFactors class. There was an error when computing the view factors - further investigation required.
Commit 151, by Thomas Egger
5 years 2 months Cosmetics, reducing output from ViewFactors
Commit 152, by Thomas Egger
5 years 2 months MPIControl: Adding a barrier method that calls MPI_Barrier() or does nothing in case MPI is not active. This can be used to synchronize anywhere in the code, mostly useful for debugging.
Commit 153, by Thomas Egger
5 years 2 months MeteoObj: There was a misconception as to which date has been prepared. The non-master MPI nodes simply assume that data is available for the correct date. Alternatively we could broadcast the date available in an async fashion.
Commit 154, by Thomas Egger
5 years 2 months MeteoObj: Sanitizing for MPI usage
Commit 155, by Thomas Egger
5 years 2 months SnowpackInterface: Cleanup before inducing MPI
Commit 156, by Thomas Egger
Jul 25, 2014
5 years 2 months SnowpackInterface: now runs with MPI and scales very well - however two issues remain: interdependecy of modules (runoff is called from within snowpack) and the writing of data, that is distributed on multiple MPI nodes (writeOutputSNO, writing runof
Commit 157, by Thomas Egger
5 years 2 months SnowpackInterface: It seems that it's enough to call the runoff->output(Date&) method from the master node only, since data is supplied solely through runoff->fillHydroTables.
Commit 158, by Thomas Egger
5 years 2 months SnowpackInterface: getting rid of that zombie code
Commit 159, by Thomas Egger
Jul 26, 2014
5 years 2 months MPIControl: Adding a gather method for ints and a pseudo gather template for vector<T*>. It's a pseudo gather, because underlying send and receives are performed. The usage of MPI_gatherv was not possible due to string size restrictions and memory de
Commit 160, by Thomas Egger
5 years 2 months SnowpackInterface: when using MPI only the master node is responsible for output. TODO: let the user decide whether only the master or all nodes are allowed to do file I/O. The second option could be relevant when using a shared filesystem.
Commit 161, by Thomas Egger
5 years 2 months MPIControl: adding comments
Commit 162, by Thomas Egger
5 years 2 months TerrainRadiation: Fixing 64-bit issue (size_t != unsigned int)
Commit 163, by Thomas Egger
Jul 27, 2014
5 years 2 months AlpineMain: only master needs to have io.ini present in the filesystem - Config object is broadcasted to all processes
Commit 164, by Thomas Egger
5 years 2 months AlpineMain: only master reads landuse, dem and pts - then broadcasts these. DEMObject had a erroneous << and >> operators. Please update MeteoIO to the latest version.
Commit 165, by Thomas Egger
Jul 28, 2014
5 years 2 months MPIControl: adding scatter, send and receive template methods for vector<T*> types. Only types that have the << and >> operator implemented can make use of these functions. Furthermore there is a master_rank() function, which returns the master rank
Commit 166, by Thomas Egger
5 years 2 months SnowpackInterface: SnowpackInterface and SnowpackInterfaceWorker have been remodelled in order to only read snow cover data through the master process. The other processes receive the data by MPI send and receive operations. This lead to restructurin
Commit 167, by Thomas Egger
5 years 2 months SnowpackInterface: writeOutputSNO now operates on the basis of send and receives only, the MPI gather method has been discarded, due to the fact, that if we have many processes, the memory demands for the master node exceed availability.
Commit 168, by Thomas Egger
5 years 2 months SnowpackInterface: Reducing the amount of memory needed by read SN_SNOWSOIL_DATA only once. This structure does not change and consequently does not need to be sent accross the MPI processes.
