Why do I get MPI_Abort errors when trying to submit a parallel job?

The core of my job submission code is below:

    jopt.email_notif = 0;

    jopt.toggleleft = left_list(j);
    jopt.toggleCausalDir = dir_list(k);
    jopt.toggleChoice = choice(l);
    jopt.od_number = od_list(i);

        jopt.connectivity = 1;

        sched = findResource('scheduler', 'configuration', 'NeuroEcon.local')
        set(sched,'SubmitArguments', '-l walltime=0:20:00')

        pjob = createParallelJob(sched);

        set(pjob, 'FileDependencies', {'multiDCMset1.m'})
        set(pjob, 'MaximumNumberOfWorkers', 1)
        set(pjob, 'MinimumNumberOfWorkers', 1)
        t = createTask(pjob, @multiDCMset1, 1, {jopt})
        t_all{1,jj}=t; jj=jj+1;
        submit(pjob);
---------------------------------------

The following is the error message I get in the job submission log, after the job finishes running. I don't understand the error or what could cause it. I do know that the same script runs fine on another person's computer. Do I need some specific settings to submit parallel jobs?

Is there any error in the task of the job? Check using:

pjob.Tasks(1).Error

or even

getReport(pjob.Tasks(1).Error)
