LSF / Extend "span[hosts=xx]" capability to several hosts to optimize cpu utilization in exclusive context

There is no way today to optimize CPU utilization over several hosts, i.e. to specify on how many servers the job should be dispatched, and let LSF use all available cpu on these hosts.

This works fine with 1 single host, using cpu range and "span[hosts=1]", yet this span feature does not handle multiple nodes so far.

This would be especially valuable in a context of heterogeneous hardware, when we cannot "guess" how many cpus are to be used if we want to occupy e.g. 2 or 3 hosts.

Besides, dedicate hosts to one single job (and make full utilization of all available cpus) allows to optimize performance, e.g. through specific mpi settings.

The possibility to get a patch for LSF 9.1.2 would be greatly appreciated.

    We have considered this request and it is not something we are able to deliver in the future. If there is broad interest for this, it can be resubmitted in 18 months.
