Hi Xiaofei,
I don't think there is. Do be sure you could best ask the CREAM
developers directly, via [log in to unmask]
Also, the Argus-specific gsi-callout library (argus-gsi-pep-callout) has
no support for multiple endpoints. That's the component used by default
by CREAM for its gridftp access, as far as I know. They could also use
the lcas-lcmaps-gt4-interface with the lcmaps-plugins-c-pep and then you
would regain the multiple endpoint support now supported by the
lcmaps-plugins-c-pep.
Best wishes,
Mischa
