Need I Call "initcuda" Multiple Times When Jitting Multiple Ptx Strings In One Application?

Hi all.
There is an example named “ptxjit” in CUDA SDK that demos how to jit the ptx string.
in the ptxjit.cpp file, there is a function named “initCUDA” which completes the context initialization and ptx text loading for ptx jitting.
My question is, need I call “initCUDA” multiple times if I want to jit multiple ptx strings in one application?

Thanks in advance!
