QFlex enables full-system microarchitectural simulation of multicores running unmodified applications and is based on QEMU. We currently support 64-bit ARM binaries in trace mode. In this first release, we also make a full CloudSuite workload image available for those who want to get a head start. More workload images will follow soon. You can download QFlex from our GitHub repo. As QFlex is a work in progress, we encourage users to use GitHub issues actively.
