sgx_bench

benchmarking memory access latencies inside intel sgx enclaves.

Prerequisites

intel sgx sdk and psw (https://github.com/intel/linux-sgx)

Build and run

source /opt/intel/sgxsdk/environment ./build_sign.sh; ./benchmark_sgx -n -r -s 100 ./build_sign.sh; numactl --membind=1 -C 30 ./benchmark_sgx -n -r -s 100

program options: -n :cross numa -r :random walk -s

Build in debug mode

make SGX_DEBUG=1 SGX_MODE=hW sgx-gdb bencgmark_sgx

The main benchmark function is at App/App.cpp: Benchmarker::Run() The round trip time of calls is measured in cycles, using RDTSCP insturction. NOTE: the file spinlock.c is taken from Intel's SGX SDK repository at (https://github.com/01org/linux-sgx)
