ESESC: A Fast Multicore Simulator

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.
