adding further compute nodes

Hi,

Is there a need to re-install Intel Studio even in the case then I added further compute nodes to my cluster? There exists two infiniband -islands,  ibstat is:

CA 'mlx4_0', CA type: MT4099 and CA 'mlx4_1', CA type: MT26428. The latest  compute nodes are associated to MT4099.

These provider -errors are only present in the 'newer node context'

One way or another you must assure that all required shared libraries are available on all nodes. As far as impi is concerned, repeating the Mpi part of the installation with an updated node list would take care of it, (after taking care of dapl and hca). Evidently, installing psxe on a shared drive simplifies this aspect of adding nodes.
