wild guess without having any additional information.
The problem might be your network. Are you sure that you have
exclusive use of the network/nodes? 
Jobs run slowly --> with constant time or strong variations of time?
Monitor your network! Monitor your load on the nodes!

Subject: [CP2K:6507] parallel running cross nodes problem

Hi, anyone  encounter the problem that, after running MD about 2000 steps, the jobs run slowly , when parallel running on more than one node.  however, running on only one node, there is no problem.
