RemoteKernelOpen

RemoteKernelOpen[spec]

launches a kernel with the given specification.

RemoteKernelOpen[{spec1,spec2,…}]

launches kernels in parallel.

更多信息和选项

  • RemoteKernelOpen is used by LaunchKernels to start a parallel kernel with the Lightweight Grid protocol.
  • The argument to RemoteKernelOpen can be a hostname, a Lightweight Grid Manager URL, a RemoteServicesAgent expression, or a RemoteService expression.
  • Use RemoteKernelClose or RemoteKernelCloseAll to close the kernel.
  • With the default setting "LocalLinkMode"->"Connect", the remote kernel creates a link and Mathematica connects to it. With "LocalLinkMode"->"Create", Mathematica creates a link and the remote kernel connects to it. Some network configurations do not allow Mathematica to connect to links created on the remote computer, requiring "LocalLinkMode" -> "Create" to establish a connection.
  • The following options can be given:
  • "LocalLinkMode""Connect"how to establish the link
    "Service"""names the service to launch
    "Timeout"30the timeout for the network connection, in seconds
