Jagurs in clustered environment

[guntutur]

Hello there, a quick question : does jagurs support running in a multi machine environment like a server cluster?
Say i have one master node with jagurs installed and configured, and 5 child node, all in one rack server on the same network. Is it possible with jagurs to utilise these 5 child node to fasten the computational time and process?

Best regards

Yes, JAGURS can use MPI for parallel running on a cluster. Please compile JAUGURS with a compile option of MPI=ON.
Thank you for having an interest in JAGURS.

Could you point me to the documentation on how to set up and installation for clustered environment? thanks

"README" file in src directory explains the installation. For JAGURS compilation, you need pre-installed libraries of NetCDF, NetCDF-fortran, HDF5, fftw, and proj4. And then you modify being correct paths to the libraries in Makefile and compile using MPI compiler (such as ifort) . If you are not familiar with parallel computing, we recommend asking your system administrator for help. Some of the libraries may be already installed in your system.

do you have any sample command to run jagurs admin within the cluster?
currently i have installed all needed libraries, including mpi and jagurs on master node
i have successfully run jagurs utilising openmpi on masternode but got stuck in utilising all the child nodes with mpi. thanks

Hi, You can access to the sample data at https://www.dropbox.com/sh/oiypdwufu31za1g/AADQ2QBRnu5BShO4Gh4989S4a?dl=0 I think that the parallel jagurs can run simply with mpirun -np # jagrus par=tsun.par Regards,
