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)

problem about running the trace of Financial1 #14

Closed gdchenahu closed 4 years ago

gdchenahu commented 5 years ago

When I run the Trace of Financial1 with MQSim, I found that when the write request is passed to the list of Waiting_user_requests in the device and the data of the write request is retrieved from the host, the write request placed in the list of Waiting_user_requests is abnormally deleted. And every time we run MQSim, the write requests that are deleted abnormally are different. Do you know what caused this?

Can you please post links to your input files (both configuration and workloads)? We need them to replicate the error.
