Subject: BoF on LPC 2019 : Linux Perf advancements for compute intensive and
 server systems

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
