| < < | The JobType must be "Normal" and the attribute NodeNumber must be defined (16 in this example). Despite the name of the attribute, this attribute defines the number of CPUs required by the job. It is not possible to request more complicated topologies based on nodes and CPUs. Please note that the maximum requestable NodeNumber is 64, but if you need more than 64 slots for a short period of time, you should write a letter to gridadm@rmki.kfki.hu. | |||||||

| < < | This example uses the OpenMPI implementation of the MPI-2 standard. This is the only MPI implementation which is supported on the RMKIGrid site. The JobType attribute must be "Normal" in all cases; it selects for an MPI job in general and not the specific implementation. | |||||||

All of the files for the above example JDL file have been defined except for the actual MPI program. This is a simple Hello World example written in C. The code is:
