Read-Copy update (RCU) in tracing

• RCU implemented in user space for LTTng-UST control

• Linux kernel using RCU synchronization scheme – extremely scalable and fast, – albeit notoriously complex.

• Production-grade library

for user-level RCU

• 280 times faster than SystemTap

Lesson’s learn › No involvement = 50%, 20% _or less_ of the potential tool benefits

› If you get involve it works! › No significant contribution to Eclipse for many years, today Ericsson

Eclipse committers or funding in many projects: CDT, Review, LinuxTools, P2, Papyrus, EMF Compare, ArCon, EGit/JGit,

Gerrit, Mylyn, PolarSys, LTS, Non Eclipse as well SCM, tracing, debug, ALM, etc

› Healthy relationship between end user companies & tool providers based on innovation!

› Start with low hanging fruits to ensure successful result, you then get a snow ball effect

Modeling context

› Modeling tools have been used in Ericsson since mid 90’s › Used for modeling different aspects

– System, software, implementation, platform, network, data

› Demonstrated benefits of modeling in many different contexts

– Currently relying mainly on commercial proprietary tools, e.g. RSA, RSA RTE, Rhapsody, BrigePoint, EA, PowerPoint

› But, they have also failed in other contexts – Modeling tools must be easier to use – Better DS(M)L support is required – Role of tools is to make designers more productive, not to add

complexity!

Public | © Ericsson AB 2013 | 2013-10-16 | Page 15

Open source Modeling tools

› Need open source alternatives to existing modeling tools › Not free!

– Less mature than open source tools covering other software development aspects, e.g. GNU, GCC, GDB since 1980

– Need to invest to contribute to the industrialization – Need to get involved and play a leadership role – We can’t wait and hope that we can get it for free. It won’t

happen!

› Key requirements for open source solution – Allow developing customization and DS(M)L – Provide integrations with other required development tools – Allow protecting our core IP’s – Offer commercial support
