The short answer is no.
When you say parallel, I assume you mean multi-threading
(as opposed to using mpi, which we can do internally).
Some groups have claimed that by putting locks around
calls to nc_open and nc_close, that they have done it
successfully for netcdf-3 files. Also, HDF5 claims to support
a multiple reader, single writer model for data, but we have
not yet investigated this.
