seed

public long seed

The seed used for the random number generator (default ).

r

public Random r

Random number generated used for sampling the starting vertices. Set by #init().

nruns

public int nruns

The #of runs per initial condition. For algorithms that use a single starting vertex (BFS, SSSP, etc.), there will be a total of nruns * nsamples runs. For algorithms that populate the initial frontier with all vertices (e.g., CC, PR), there will be a total of nruns.

nsamples

public int nsamples

The #of random starting vertices to use for algorithms that use a single starting vertex in the initial frontier and otherwise ignored.

nthreads

public int nthreads

The #of threads to use for GATHER and SCATTER operators.

analyticClass

public Class<IGASProgram<VS,ES,ST>> analyticClass

The analytic class to be executed.

schedulerClassOverride

public Class<IGASSchedulerImpl> schedulerClassOverride

The IGASSchedulerImpl class to use. TODO Override or always? If always, then where to get the default?

loadSet

public final LinkedHashSet<String> loadSet

Set of files to load (may be empty).

propertyFile

public String propertyFile

The name of the implementation specific configuration file.

Method Detail

init

public void init()
          throws Exception

Initialize any resources, including the connection to the backend.

Throws:

Exception

shutdown

public void shutdown()

Shutdown any resources, including the connection to the backend.

Note: This method must be safe. It may be called if init() fails. It may be called more than once.

handleArg

public boolean handleArg(AtomicInteger i,
                String[] args)

Return trueiff one or more arguments can be parsed starting at the specified index.

Parameters:

i - The index into the arguments.

args - The arguments.

Returns:

true iff any arguments were recognized.

usage

public void usage(int status,
         String msg)

Print the optional message on stderr, print the usage information on stderr, and then force the program to exit with the given status code.

Parameters:

status - The status code.

msg - The optional message

report

public void report(StringBuilder sb)

Extension hook for reporting at the end of the test run.

Parameters:

sb - A buffer into which more information may be appended.
