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'
