[diamon-discuss] Next meeting: glibc tracing, Friday December 16th, 1PM EST (6PM UTC)

Hi,

The next call is this Friday, Carlos O'Donell and DJ Delorie from Red
Hat will present the work they have started to get glibc instrumented.

See you on Friday !

Title: Whole-system benchmarking and glibc's tracing requirements

Abstract:
The vision behind glibc’s whole-system benchmarking is to provide
tooling to measure and characterize a user workload larger than a
microbenchmark (glibc already has a microbenchmark framework).

Once the workload is characterized it should be possible to evaluate
the merits of larger performance-related changes in the core library
against a given set of workloads.

The Red Hat glibc team has started this work by using a custom
in-process tracer for the malloc family of API calls. Knowledge gained
from this experience has given the team key insights into the kind of
tracing requirements that will be needed to approach the rest of the APIs.

The presentation will focus on the initial work done by the Red Hat team
and the obstacles facing broader adoption of a tracing framework within
glibc.
