That's right Martin. For each thread, I just call
system("globus-credential-delegate ... ") and use the epr in
system("globusrun-ws ...."). That's where I do not get any error. If, however,
I call system("globusrun-ws ...") on each thread using a single epr (created in
the shell script before running the C program), then I started getting RSL
stagein element error.
Thanks a lot Martin for looking at this.
