FOSDEM event "XALT: Lessons from attaching to almost every program in Linux"

Robert McLay

Type devroom

Starts on day 1 (2021-02-06) at 16:00 (Brussels time, UTC+1) in room Hpc (duration 00:30)

Matrix room #hpc:fosdem.org

XALT is a tool run on clusters to find out what programs and libraries

are run. XALT uses the environment variable LD_PRELOAD to attach a

shared library to execute code before and after main(). This means

that the XALT shared library is a developer on every program run under

linux. This shared library is part of every program run. This talk

will discuss the various lessons about routine names and memory

usage. Adding XALT to track container usage presents new issues

because of what shared libraries are available in the container.
