Storage Repository Abstraction     Dec 2003

A comparison of the function calls issued by five different systems has been conducted
(Dec 2002).  The systems include the Storage Resource Broker (SRB), Condor (Chirp),
dCache access protocol (DCCP), RFIO functions used in Root, and the MPI-IO access functions.
Each system implements a set of C library calls, which use the specified operation prepended
by a C library call prefix.  (For example srbopen, client.open, dc_open, rfio_open, MPI_FILE_open)
An "x" in a cell of the following table indicates that the function is provided.
