Follow-up on previous video: Making the benchmark scale better
Переглядів 632 місяці тому
In this video we follow-up on an oddity from the previous video: the lack of scalability of the sum-of-squares benchmark, when running with 2, 3 or 4 (or whatever number of physical cores are present on a computer) workers vs one. We use the classic Trace Compass to look at new traces obtained after some minor adjustments, that fix the previously mentioned issue. Benchmark: github.com/MatthewKh...
Eclipse Trace Compass: Showing an unbalanced workload and benchmarking issues through kernel tracing
Переглядів 1232 місяці тому
In this video we use Trace Compass to look at an odd behaviour. A benchmark where a fixed load is split among many threads is slowing down when we add more cores. The results were surprising. The worker threads would finish at different times and therefore we needed to wait for the longest worker. We utilize the Theia based front end for this demo as it allows exploration by CPU usage rather th...
Eclipse Trace Compass: How to record an LTTng Kernel and Userspace trace and read the results
Переглядів 1503 місяці тому
This is a demo of how to trace your application easily and view the results. It is an effective hello world in low level tracing. We use LTTng, lttng-utils, and Eclipse Trace Compass in order to monitor the performance of a given program. The program tests memory access patterns and compares x-then-y vs y-then-x vs memset for performance.

XZ-tool backdoor traced using uftrace, Visualized in Trace Compass
Переглядів 4255 місяців тому
This is showing a quick flow of how you can compare two runs. This explores the XZ backdoor. I did not find data as compelling as Andres Freund did. This is an attempt to find a way to visualize the backdoor in a tool rather than an infographic. The major takeaway is also that libraries have a major impact on execution flow too. It is quite visible with this trace. the command used is: echo exi...
Eclipse Trace Compass Automatic Trace Clock Synchronization for Critical Path Analysis
Переглядів 1355 місяців тому
Trace Compass's Critical path analysis can handle traces from multiple nodes, servers, or computers. This brings up the issue, how can we synchronize clocks. NTP is good, but sometimes we can have clock skews of 10 seconds, this is not acceptable for nanosecond precision traces. Different clocks can even drift at different temperatures! We show the simple solution here. If you're interested in ...

Explaining "Bottlenecks" using Trace Compass
Переглядів 2117 місяців тому
This video is intended for a slightly different audience than the rest of the trace compass videos. Trace Compass is used here to illustrate points. What is a bottleneck? Performance bottlenecks are like traffic jams in your computer. They occur when one part of the system slows down the rest, hindering overall performance. This video explains how bottlenecks can happen, how to prove which comp...

Nice job Vlad!
Truly a great intern!
DTW. Dynamic time warp. Would align automatically
We support DTW, in fact we have the first implementation of LIANA. www.sciencedirect.com/science/article/abs/pii/S1084804514001623 However, this would not help in the context of flame graphs, but flame charts. Here is a video describing the difference. ua-cam.com/video/ZrjuJKjAUns/v-deo.html . Basically a flame chart shows your callstack vs time, a flame graph is a weighted tree of function durations that are aggregated from a callstack over time. Also, we find the naming (Flame Graph/Flame Chart) to be confusing. Callstack over time and flame graph would be clearer. However, we tried to align with industry standard nomenclature. Thanks for the comment!
Nice video! Can you tell me if lttng-record-trace (lttng-utils) is currently maintained somewhere? I added some feature to perform the tracing on a embedded remote target via ssh and I would be happy to share this.
As far as we know, it's here github.com/dorsal-lab/lttng-utils I think we should update the readme to reflect that. LTTng utils is unsupported. It is a good will project, but nobody really supports it. I am certain that dorsal would love a new maintainer. ;)
Cool and Great work
Thank you!
Looks nice, great work!
Thank you so much!
Well done!
Thanks! We're glad to see ways we can help!
Cool!
Thanks for the amazing video. Any idea how Tracecompass builds a critical path analysis for a thread. When I look at the order of kernel events they map to the control flow view and not critical flow view. Would be great to know how Tracecompass deduces it from trace events?
You can look in the source code, it's open source. But basically the linux kernel is well instrumented. We know stuff like sched wakeup, switch etc.. and we can get more data like syscalls for files and network access. I cannot go into too much detail in a youtube comment, but reach out to the community @ tracecompass.org for a better deep dive!
Is it normal to have to manually place Jaeger Tracing in the application to be able to place the body inside Jaeger Web or is there an automatic way to see the body on a Tracing platform like Jaeger Web?
We do! git.eclipse.org/r/c/tracecompass.incubator/org.eclipse.tracecompass.incubator/+/127410 No users expressed the need for this! If there is a need we can accommodate, or if you have a cooler way to do it, please share a patch, we'll review with giant smiles!
What GDB version is used in this demo? GDB tracepoints have been broken for a while now AFAIK.
GNU gdb (Ubuntu 9.2-0ubuntu1~20.04.1) 9.2 Sorry, I should have answered faster. I didn't notice the message. I love your nickname btw.
Wow, this looks so awesome! Can't wait to check it out. I've just implemented a (near-)zero-overhead PHP Stacktrace capturer and Flamegraph generator. The information you get out of flamegraphs is just amazing. Would love to capture the information for a whole server like you did. Do you have a tutorial, where I can learn to capture the data on a linux production server without overloading the server?
Hey, sorry for the long delay, I thought I answered it. check out www.tracecompass.org for the tutorials, there's a project called tracevizlab. We hope to see interractions/collabs soon!
Hi Matthew, lets agree to disagree about the relative coolness of GDB tracing vs lttng. It's true that lttng is way more flexible, faster, easier to capture traces for, has less limitations, and more. But is it cooler? Are CDs cooler than vinyls? I think not. Other than that little detail, excellent video! :)
I cannot argue with such wisdom. GDB tracing has some very nice use cases. IMO it's much easier to set up, but you get less information out of it. As an individual who likes getting the full picture, that is limiting. :) The best though, is integrating a GDB Trace with a system trace and a cloud trace to get the full pic of what's going on.
Very slick and a nice explanation for why overclocking is such a dicey proposition.
We just report the facts. If someone wants to lose efficiency for speed and they live in the antarctic and have solar/wind power. Go for it!
Good video!
