CMU-SAFARI / MQSim

MQSim is a fast and accurate simulator modeling the performance of modern multi-queue (MQ) SSDs as well as traditional SATA based SSDs. MQSim faithfully models new high-bandwidth protocol implementations, steady-state SSD conditions, and the full end-to-end latency of requests in modern SSDs. It is described in detail in the FAST 2018 paper by Arash Tavakkol et al., "MQSim: A Framework for Enabling Realistic Studies of Modern Multi-Queue SSD Devices" (https://people.inf.ethz.ch/omutlu/pub/MQSim-SSD-simulation-framework_fast18.pdf)

Hello, I am sorry to bother you but i meet some question that is very unfriendly,the question is that when i run MQSim,it always remain in the SSD Device preconditioning started........ in the scenario of IO traced based ,all Configuration used is original. hope you can give me some advice ,thank you.

Hi @xiaobuding-cx,

Can you please provide us with more details regarding your executions? Especially, I need to know your OS and compiler version used for running the simulator.

Best regards, Arash

thanks you for replay @tavakara , I use the Ubuntu system and eclipse C++ to run the simulator . Sometimes This problem appear when i use the linux terminal ,sometimes it also disappear as i run several more times， but in the eclipse ，it will only be normal at the beginning. So i choose VS2019 to run , it made another mistake: "Unhandled address distribution type in FTL's preconditioning function." I can run normally by defining the Address distribution in advance ,but i did'n know clearly where the problem lies.

Best regards, xiaobuding
