This document lists and provides the description of the name (keywords) of parallelisation input variables to be used in the main input file of the abinis code.
The new user is advised to read first the new user's guide, before reading the present file. It will be easier to discover the present file with the help of the tutorial.
When the user is sufficiently familiarized with ABINIT, the reading of the ~ABINIT/Infos/tuning file might be useful. For response-function calculations using abinis, the complementary file ~ABINIT/Infos/respfn_help is needed.
The option localrdwf=0 is NOT allowed when mkmem==0 (or, for RF, when mkqmem==0, or mk1mem==0), that is, when the wavefunctions are stored on disk. This is still to be coded ...
In the case of a parallel computer with a unique file system, both options are as convenient for the user. However, if the I/O are slow compared to communications between processors, (e.g. for CRAY T3E machines), localrdwf=0 should be much more efficient; if you really need temporary disk storage, switch to localrdwf=1 ).
In the case of a cluster of nodes, with a different file system for each machine, the input wavefunction file must be available on all nodes if localrdwf=1, while it is needed only for the master node if localrdwf=0.
