I have several questions about integration of openmpi with resource queuing systems.
1. I understand that openmpi supports integration with various resource distribution systems such as SGE, LSF, torque etc. I need to build an openmpi application that can interact with variety of different resource distribution systems, since different customers have different systems. Based on my research, it seems that I need to build a different openmpi installation to work, e.g. create an installation of opempi with grid and create a different installation of openmpi with LSF. Is there a way to build a generic installation of openmpi that can be used with more than 1 distribution system by using some generic mechanism? 2. For integration with LSF/grid, how would I specify the memory (RAM) requirement (or some other parameter) to bsub/qsub, when launching mpirun command? Will something like below work to ensure that each of the 8 copies of a.out have 40 GB memory reserved for them by grid engine? qsub -pe orte 8 -b y -V -l m_mem_free=40G -cwd mpirun -np 8 a.out 3. Some of our customers use custom distribution engine (some non-industry-standard distribution engine). How can I integrate my openmpi application with such system? I would think that it should be possible to do that if openmpi launched/managed interaction with the distribution engine using some kind of generic mechanism (say, use a configurable command to launch, monitor, kill a job and then allow specification of a plugin define these operations with commands specific to the distribution engine being in use). Does such integration exist in openmpi? Thanks, Vipul
