System Call Traces

System-Call I/O Traces typically reflect operating system calls to the file system.

Some system-call traces can also be found in the Parallel Traces section.

[There are no traces less than 10 years old for this tracetype.]

WARNING: These traces are over 10 years old! They should not be used for modern research!

FIU Filesystem SysCall Traces System-call traces from "Non-blocking Writes to Files" in the Proceedings of the USENIX Conference on File and Storage Technologies, February, 2015. The six main traces are all one day of traces collected on 09/16/2014. All the systems were running Linux using the ext4 and zfs file systems. The two replayed traces are two minute traces collected while replaying the original Mobibench traces. The replay was done on a Linux system using an ext4 file system. System-call traces taken on six machines in 2014. Two additional traces from replaying the original Mobibench traces. 2014 7 days 453 Million 3.85 GB
MobiGen Traces 2 minute I/O traces generated using the Mobigen tool. Information about the tool is described in the README file. These traces are related to the paper I/O Stack Optimization for Smartphones by Sooman Jeong, Kisung Lee, Seongjin Lee, Seoungbum Son, Samsung Electronics, and Youjip Won. 2 minute I/O traces collected on a Samsung Galaxy smartphone. 2013 5 minutes 97.8 Thousand 19.3 MB

LASR Traces (ASCII) I/O traces taken at the system-call level in 2000 and 2001 as part of a security research project. The traces cover thirteen computers used for software development by CS researchers. The longest trace (machine02) runs from June 2000 to August 2001.

The traces are further described in a README file.

Seer Traces (ASCII) I/O traces taken at the system-call level, excluding reads and writes but including opens, closes and all other I/O calls, and including process-related calls such as fork and exec. The traces cover nine laptop computers used for software development by CS researchers, some with very heavy activity. The longest trace (norgay) extends from April 2, 1996, to January 28, 1997; the shortest (crockett) is October 11 to November 19, 1996. All traces contain gaps representing times when the machines were rebooted or the trace software failed. Activity by the superuser is generally omitted.

Additional information about these traces can be found here.
