-a appID:
              unique number for each application in the workflow

       -c config: data specification config file

       -d ...
              define process decomposition:

       d1:    number of processes in 1st (slowest) dimension

       dN:    number of processes in Nth dimension d1*d2*..*dN must equal the number of processes

       -D ... define process decomposition ratio:

       r1:    ratio of process decomposition in the 1st (slowest) dimension

       rN:    ratio  of  process  decomposition  in  the  Nth  dimension  r1xr2x..xrN  must  scale up to process
              countcount without remainder

       -s OR -w:
              strong or weak scaling.  Dimensions in config are treated accordingly

       -x file
              ADIOS configuration XML file

       --hdf5 Use native Parallel HDF5 instead of ADIOS for I/O

       -v     increase verbosity

       -h     display this help

       -F     turn on fixed I/O pattern explicitly

       -T     turn on multi-threaded MPI (needed by SST/MPI)

       -p     specify the path of the output explicitly

       -t     print and dump the timing measured by the I/O timer
