Getting the Source
NEKCEM is available for download via the Subversion repository:
svn co https://svn.mcs.anl.gov/repos/NEKCEM
It is also recommended to download ParaView.
Contents of NEKCEM package
The NEKCEM package contains the source code, scripts, examples, libraries used, and documentation.
- src: source code
- bin: a collection of scripts for building and running NEKCEM
makenek: To compile for serial runs ../../bin/makenek under an 'example' dir; See makenek --help for options
makenekmpi: To compile for parallel runs ../../bin/makenekmpi under an 'example' dir;
nek: To run ../../bin/nek; See nek --help for options
cleanall: To clean ../../bin/cleanall
- examples: sample problems including SIZEu, *.rea, *.map, *.usr (some special cases have additional files)
- libs: BLAS and LAPACK can be placed here if not already installed on your system
- tool: source codes for other utilities, mainly for meshing (detail below)
- doc: documentation
Compile
cd NEKCEM/trunk/examples/cylwav (serial) ../../bin/makenek cylwave
cd NEKCEM/trunk/examples/cylwav (parallel) ../../bin/makenekmpi cylwave
Execute
cd NEKCEM/trunk/examples/cylwave ../../bin/nek cylwave (serial)
cd NEKCEM/trunk/examples/cylwave ../../bin/nek cylwave #np (parallel)
Note: on Intrepid, #np is the number of node (total number of cores will be #np*4)
Note: on Jaguar, do ../../bin/nek cylware #np1 #np1, where #np1 is the actual core number you need,
and #np2 is the core number you request from system, which has to be a multiple of 16.
