Abstract-Recently, both industry and academia have proposed many different roadmaps for the future of DRAM. Consequently, there is a growing need for an extensible DRAM simulator, which can be easily modified to judge the merits of today's DRAM standards as well as those of tomorrow. In this paper, we present Ramulator, a fast and cycle-accurate DRAM simulator that is built from the ground up for extensibility. Unlike existing simulators, Ramulator is based on a generalized template for modeling a DRAM system, which is only later infused with the specific details of a DRAM standard. Thanks to such a decoupled and modular design, Ramulator is able to provide out-of-the-box support for a wide array of DRAM standards: DDR3/4, LPDDR3/4, GDDR5, WIO1/2, HBM, as well as some academic proposals (SALP, AL-DRAM, TL-DRAM, RowClone, and SARP). Importantly, Ramulator does not sacrifice simulation speed to gain extensibility: according to our evaluations, Ramulator is 2.5× faster than the next fastest simulator. Ramulator is released under the permissive BSD license.

“…McSimA+ is a multicore application-level+ simulator with detailed micro-architecture modeling [4]. While it was developed to offer a level of functionality that lies between an application and a full-system simulator (hence application-level+), its main purpose is to achieve higher simulation speeds in comparison with other common full-system simulators.…”

“…McSimA+ has been verified to execute diverse benchmark programs with high IPC (instruction per cycle) accuracy in comparison to real server execution [4]. Simulations in the combined simulator, however, will differ in IPC owing to following reasons: Firstly, the virtual-to-physical address translation described in Section 3 might improve the memory performance as different virtual addresses may point to the same physical address.…”

Fast and Accurate Memory Simulation by Integrating DRAMSim2 into McSimA+

Abstract:Computer architecture simulators play a crucial role in the verification of a new system's design. However, a single simulator may not be sufficient in covering detailed modeling of the entire system, thereby lacking in the simulation of a specific functionality under investigation. In this case, combining two simulators is necessary to compensate for the drawbacks of a single simulator. This paper proposes the integration of DRAMSim2, a simulator that thoroughly models DDR-SDRAM main memory architecture, into the application-level+ simulator McSimA+. The challenges of achieving an efficient integration, especially the integration of a cycle-accurate simulator into an event-driven environment, are addressed. The combined simulator achieves high accuracy due to cycle-accurate simulation while maintaining high speed and flexibility of the event-driven application-level+ simulator. The new simulator's overall system performance and the accuracy of the newly-integrated power model are verified against the gem5 simulator.

Abstract.Computer System Architecture (CSA) simulators are generally used to develop and validate new CSA designs and developments. The goal of this paper is to provide an insight into the importance of CSA simulation and the possible criteria that differentiate between various CSA simulators. Multidimensional aspects determine the taxonomy of CSA simulators including their accuracy, performance, functionality and flexibility. The Sniper simulator has been selected for a closer look and testing. The Sniper proofs its ability to scale to hundred cores with a wide range of functionality and performance.
