  1. Submitting A Datagrid Job Steve Traylen GridPP Manchester 10th May 2002 s.m.traylen@rl.ac.uk

  2. Hello World - JDL #############Hello World Job######### Executable = "/bin/echo"; Arguments = "Hello World "; StdOutput = "hello.out"; StdError = "hello.err"; OutputSandbox = {"hello.out","hello.err"}; ######################################

  3. Submit Hello World

  4. Hello World – Jobs Life Cycle • Job’s Life Cycle: • Submitted on a RAL UI. • Submitted to a RB at Cern. • CERN's RB chooses a destination. • Submitted to the compute element. • Executes on a worker node. • Output collected through the RB.

  5. Hello World Status

  6. Hello World Output

  7. Publishing and Finding Data • First Job: random-pairs.jdl • Generates pairs of random numbers. • Saves output to a storage element. • Data location published to a replica catalogue. • Second Job: euclid.jdl • Locates data and chooses a close CE. • Calculates GCD of each pair of numbers.

  8. Random Pairs JDL • JDL: prime-pairs.jdlExecutable = "random_pairs.sh";StdOutput = "random_pairs.out";StdError = "random_pairs.err";InputSandbox = {"random_pairs.sh","random_pairs"};OutputSandbox = {"random_pairs.out","random_pairs.err"};
