What is ESESC?
ESESC is a fast multiprocessor simulator with detailed power, thermal, and performance models for modern out-of-order multicores. ESESC is an evolution of the popular SESC simulator (Enhanced SESC) that provides many new features.
The main ESESC characteristics are the following:
- It is very fast (over 40MIPS with sampling)
- Uses QEMU and supports user mode RISCV and MIPS64r6 ISA
- Models OoO and InOrder cores in detail (ROB, Instruction Window, etc)
- Supports configurable memory hierarchy, and on-chip memory controller
- Supports multicore, homogeneous and heterogeneous configurations
- Simulates multithreaded and multiprogram applications
- Models power and temperature in addition to performance, and their interactions
ESESC is a significant evolution/improvement over SESC:
- ESESC has RISCV and MIPS64r6 ISA, sesc had MIPS ISA.
- ESESC can run unmodified Linux RISCV and MIPS binaries, sesc required a custom toolchain.
- ESESC uses QEMU for emulation, sesc had a custom emulator.
- ESESC is integrated with McPat, sesc had an older Wattch model.
- ESESC has a brand new memory hierarchy, sesc had a more complex coherence.
- ESESC has improved thermal modeling, sesc had HotSpot
- ESESC has many types of sampling (statistical, smarts, simpoint), sesc had none.
- ESESC is actively maintained, sesc is no longer mantained.
- ESESC has many bugs solved.
For more information on running ESESC see the docs directory. Use the gitter discussion group for questions.
