In the case of the kernel profile for mosa, hostname does not report the ip addresses so the workers do not know them.  In a previous email thread( [Swift-devel] [ZeptoOS] hostname  returns none in Surveyor) we discussed about how to get the worker node ip addresses using personality.sh and some netmasking(attributed to Zhao, thanks!).  Emalayan you specified that for now you can use the approach of using the torus rank 0 for the mosa manager and the mosa workers will just connect back to torus rank 0.  In a previous email to me you specified that this approach will work for the experiments you are planning for SC but you would need a better way for other mosa deployments.
