Hi guys, My team and I have finished going over the latest draft of DRMAA2, and we have some comments, suggestions and questions about it. We want to hear your opinion about these issues. 1. Given a *jobId*, you can easily get its *Job* object using the method *JobSession::getJobs(in JobInfo filter)*, if you give has as a filter a * JobInfo* with the wanted *jobId* (maybe it would be an easier shorthand if DRMAA had a method *JobSession::getJob(string jobId)*, but this is a different issue). *But*, given a *jobArrayId*, there is no way to get its *JobArray* object, which is a great limit of DRMAA that doesn't really let users to use the *JobArray* feature in DRMAA as it is used in most batch systems. I think that there should be added a similar method *JobSession::getJobArrays(in JobArrayInfo filter)*, or at least a method *JobSession::getJobArray(string jobArrayId)*. 2. A very important feature that many batch systems support is the ability to limit the number of jobs in a job array that may run simultaneously (in LSF it's called "Slot Limit" and you can read about it at http://www-cecpv.u-strasbg.fr/Documentations/lsf /html/lsf6.1_admin/G_jobarrays.html#26618). I think that DRMAA can also support this feature by: 1. Change the method *JobSession::runBulkJobs* so it will also accept an optional argument *in long slotLimit* (if it's *UNSET* then no slot limit will be assigned to the new job array). 2. Add a new method *JobArray::changeSlotLimit(in long slotLimit)* 3. There are some parameters that most batch systems allow changing for already submitted jobs, but DRMAA doesn't support changing them. For example, DRMAA doesn't let you change the priority or queue of an already submitted jobs. I think that methods *Job::changePriority(in long priority) *and *Job::changeQueue(in string queueName)* should be added. 4. Many batch systems allow rerunning existing jobs. Although DRMAA has a field called *rerunnable* in the *JobTemplate* struct, it doesn't allow users to actually rerun jobs. Maybe a method *Job::rerun()* could be added to DRMAA. 5. I have a question. Does DRMAA support Generic Resources? (for example, if I have a cluster where some of its nodes have GPU cards, and I want to submit jobs that require a certain amount of GPUs, so I would like the batch system to manage it for me, as many batch systems know how to manage). Thank you for reading all of this. I would very like to hear what you think about each of the bullets above. Regards, Nadav
