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)

run syntax #26

Closed sac2019 closed 4 years ago

sac2019 commented 5 years ago

hi, should we use two xml files: workload.xml and ssdconfig.xml for run? when I type the following commands: ./MQSIM -i ssdconfig.xml -w workload.xml

this error appears: terminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc aborted (core dumped)

thanks

Dear @sac2019 , Both xml input files are required for MQSim execution. Can you please send us your SSD configuration and workload definition files, so that we can investigate the issue? Thanks, Arash

I use the default workload and ssd config file.

I change the default workload file (decrease the number of channel and Die), the problem is solved. it seems two default files (ssdconfig and workload) do not not match.
