Re: Mathematica 8 remote parallel kernels
Perhaps you are exceeding your quota of kernel licences? (Particularly likely on a shared server where others may or may not also be using some of the available licences at any given time.) Another possibility, if you are trying to launch a large number of parallel kernels, is that you are running into some kind of limitation on the number of concurrent TCP/IP connections. Other than that, it is likely platform-dependent, but you do not mention what platform you are using. Correctly setting up Windows client-to-Windows server parallel kernel operation is slightly more difficult than for the other platforms, for example.

Thanks in advance I hope you can help me with this.
