performance optimization within enclave

Matthias_H_Intel — Mon, 13 Jun 2016 15:22:55 GMT

Is there any tool (SEP, VTune ...) which would allow to somehow analyze enclave SW (non release, e.g. debug build). If so, is there any documentation?

An enclave is an isolated environment. Performance analysis tools such as AQtime*, perf tools, VTune*, Valgrind* are not supported inside an enclave. The Intel® Software Guard Extensions Evaluation SDK provides a tool called sgx_emmt to measure the real usage of protected memory by the enclave at runtime.

Chapter 7 of the PRM details some of the performance / debugging that is available in the architecture:

Searching for SGX in the VTune release notes indicates which version of VTune has some support for SGX:

EDIT:
However, version 1.1 of the software does not include support for VTune.
