Solution 1:[1]

What you cannot do: have more that 1 program (or process) to use an enclave. Only the process that has created the enclave can use it.

What you can do: have more that 1 thread inside an enclave, but you have to create them in the untrusted part of the app. In your XML enclave config file there are 2 values, TCSNum and TCSPolicy.
