Thorn IOPanda

Thorn IOPanda registers an I/O method called IOPanda with the I/O interface in the flesh. This method creates three-dimensional output of 3D grid functions. (and possibly multidimensional arrays, which are not implemented fully in Cactus yet). Panda library integrated into IOPanda thorn has been modified and currently it supports to write array data in IEEEIO binary format. It will be modified again so that it can support output in HDF5.

Data written by panda goes into files named "<varname>.<rank_of_io_processor>" and will be placed in the directory which is specified in the input paramemter file. Futher processing of these data can be done with visualization tools like Amira, AVS, and IDL.

Checkpoint/recovery operations are not implemented yet and will be included in the thorn soon.
