| == VASP binaries ==
| | #REDIRECT [[HPC/Applications/vasp]] |
| Some options for VASP cannot be configured at runtime (by input data) but must be chosen when compiling.
| |
| Since no single set of compile-time choices is appropriate for all uses, a number of binaries are provided, distinguished by their name.
| |
| | |
| The vasp5 modules from version vasp5/5.2.12a-mkl-4 onwards
| |
| contain several binaries built using different sets of preprocessor flags in the Makefile.
| |
| Earlier modules only contain two binaries, <code>vasp</code> and <code>vasp-gamma</code>.
| |
| Additional binaries are provided for useful preprocessor flag combinations
| |
| after applying patches from the group of Graeme Henkelman (UT Austin) to the source code:
| |
| * [http://theory.cm.utexas.edu/vtsttools/ Transition state tools for VASP], and
| |
| * [http://theory.cm.utexas.edu/vtsttools/bader/ DOS Projection in Bader Volumes].
| |
| | |
| To verify the binaries available for a module, run, once the module has been loaded:
| |
| ls $VASP5_HOME/bin
| |
| | |
| Copy a sample job script from:
| |
| $VASP5_HOME/vasp.job
| |
| | |
| Choose a binary appropriate for your task and pass it to <code>mpirun</code> in the job script. There is no need for full path names.
| |

| === Explanantion of flags ===
| |
| From <code>vasp.5.2/makefile.linux_pg</code>
| |
| <pre>
| |
| #-----------------------------------------------------------------------
| |
| # possible options for CPP:
| |
| # NGXhalf charge density reduced in X direction
| |
| # wNGXhalf gamma point only reduced in X direction
| |
| # avoidalloc avoid ALLOCATE if possible
| |
| # IFC work around some IFC bugs
| |
| # CACHE_SIZE 1000 for PII,PIII, 5000 for Athlon, 8000 P4
| |
| # RPROMU_DGEMV use DGEMV instead of DGEMM in RPRO (usually faster)
| |
| # RACCMU_DGEMV use DGEMV instead of DGEMM in RACC (faster on P4)
| |
| # **** definitely use -DRACCMU_DGEMV if you use the mkl library
| |
| #-----------------------------------------------------------------------
| |
| …
| |
| #-----------------------------------------------------------------------
| |
| # additional options for CPP in parallel version (see also above):
| |
| # NGZhalf charge density reduced in Z direction
| |
| # wNGZhalf gamma point only reduced in Z direction
| |
| # scaLAPACK use scaLAPACK (usually slower on 100 Mbit Net)
| |
| #-----------------------------------------------------------------------

| === Common flags ===
| |
| -DIFC -DRPROMU_DGEMV -DRACCMU_DGEMV -DCACHE_SIZE=16000 -DMPI -DMPI_BLOCK=8000

| == vdW-DF functional ==
| |
| All binaries support the use of the [http://cms.mpi.univie.ac.at/vasp/vasp/vdW_DF_functional_Langreth_Lundqvist_et_al.html vdW-DF functional of Langreth and Lundqvist et al.]
| |
| | |
| No specific preparations are needed other than setting the INCAR flags as documented. The binaries will find the required precalculated kernel file <code>vdw_kernel.bindat</code> by means of the environment variable <code>$VASP5_HOME</code> which is set by the module. This is a Carbon-specific extension.
