01_nc_create_par: Create a parallel NetCDF File
In pbdNCDF4: Programming with Big Data -- Interface to Parallel Unidata NetCDF4 Format Data Files

Description Usage Arguments Details Value Author(s) References See Also Examples

Creates a new parallel NetCDF file on a parallel file system, given the variables the new file is to contain.

1 2	nc_create_par(filename, vars, force_v4 = TRUE, verbose = FALSE, comm = 0L, info = 0L)

`filename`	Name of the NetCDF file to be created.
`vars`	Either an object of class `ncvar4` describing the variable to be created, or a vector (or list) of such objects to be created.
`force_v4`	If `TRUE`, then the created output file will always be in parallel netcdf-4 format which supports more features, but cannot be read by version 3 of the netcdf library. `FALSE` is not allowed.
`verbose`	If `TRUE`, then information is printed while the file is being created.
`comm`	a communicator number from pbdMPI.
`info`	a info number from pbdMPI.

See nc_create for details. The parallel version is able to coordinate with other nc_create_par instances for more efficient operation in parallel.

An object of class ncdf4, which has the fields described in nc_open.
