Examples

Job Submission

C++:

#include <saga/saga.hpp>

int main (int argc, char** argv)
{
  namespace sa  = saga::attributes;
  namespace sja = saga::job::attributes;

  try 
  {
    saga::job::description jd;

    jd.set_attribute (sja::description_executable, "/home/user/hello-mpi");
    jd.set_attribute (sja::description_output, "/home/user/hello.out");
    jd.set_attribute (sja::description_error, "/home/user/hello.err");

    // Declare this as an MPI-style job
    jd.set_attribute (sja::description_spmd_variation, "mpi");

    // Name of the queue we want to use 
    jd.set_attribute (sja::description_queue, "checkpt");
    jd.set_attribute (sja::description_spmd_variation, "mpi");
    // Number of processors to request 
    jd.set_attribute (sja::description_number_of_processes, "32");

    saga::job::service js("gram://qb1.loni.org/jobmanager-pbs");
    saga::job::job j = js.create_job(jd);

    j.run()
  } 
  catch(saga::exception const & e) 
  {
    std::cerr << "SAGA exception caught: " << e.what() << std::endl;
  }
}

Python:

import saga

try:
  jd = saga.job.description()
  
  jd.executable = "/home/user/hello-mpi"
  jd.error  = "/home/user/hello.err"
  jd.output = "/home/user/hello.out"
  
  # Declar this as an MPI-style job
  jd.spmd_variation = "mpi"
  
  # Name of the queue we want to use 
  jd.queue = "checkpt"              
  jd.job_project = ["TG-XXXxxxXXX"]  
  # Number of processors to request
  jd.number_of_processes = "32"
  
  # URL of the resource manager. In this case Globus GRAM
  js = saga.job.service("gram://qb1.loni.org/jobmanager-pbs")

  job = js.create_job(jd)
  job.run()
  
except saga.exception, e:
  print e.get_all_messages()
