Overview
-
-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
-sOR-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
