Abstract: Both 3rd generation Xeon scalable processors and Gramine 1.0, which potentially improves the performance of Intel SGX, were released in 2021. In this paper, we provide the first performance analysis of HPC workloads with Gramine and SGX on 3rd generation Xeon scalable processors. Our analysis starts with some microbenchmarks and is then extended to various HPC workloads. Our experimental results show that Gramine+SGX shows a small performance overhead (4-17%) for both compute-intensive and memory-bandwidth-sensitive workloads but a bit large performance overhead (up to 170%) for a memory-latency-sensitive workload. In addition, we show that the combination of Gramine and a 3rd generation Xeon scalable processor shows a slowdown of 1.5x on average (up to 4.4x) for many HPC workloads. This number is an order of magnitude smaller than that reported in the previous work using the combination of the former generation SGX toolchain and processor.
