Hi,

There is a BoF session scheduled on Linux Plumbers Conference 2019 event.
If you plan attend the event feel free to join and discuss about the BoF
topic and beyond:

Linux Perf advancements for compute intensive and server systems:

"Modern server and compute intensive systems are naturally built around
several top performance CPUs with large amount of cores and equipped
by shared memory that spans a number of NUMA domains. Compute intensive
workloads usually implement highly parallel CPU bound cyclic codes
performing mathematics calculations that reference data located in
the shared memory. Performance observability and profiling of these
workloads on such systems have unique characteristics and impose specific
requirements on software performance tools. The requirements include
tools CPU scalability, coping with high rate and volume of collected
performance data as well as NUMA awareness. In order to fulfill that
requirements a number of extensions have been implemented in Linux Perf
tool that are currently a part of the Linux kernel source tree
[1], [2], [3], [4]"

Best regards,
Alexey
