The DDS Interoperability Demo - Reloaded

In a few hours we are going to demonstrate interoperability between different DDS implementations, namely PrismTech's OpenSplice DDS, RTI's DDS, and TwinOaks CoreDX.

This time I'll be demonstrating the interoperability of OpenSplice DDS Community Edition, namely the Open Source version of OpenSplice DDS.

More later.

Ciao!

The OMG Real-Time Workshop

Following a tradition established over the course of many years, the OMG Real-Time Workshop goes live again tomorrow. The 2009 edition (see http://bit.ly/vcGCd) is strongly centered around DDS, showing how this technology is really picking and quickly walking the path toward becoming the next big thing.

The first day of the Workshop, Monday the 13th, will be full dedicated to Tutorial and will features:

• OMG DDS Tutorial (full day)
• UML Profile for DDS Tutorial (Half Day)
• UML profile for Modeling and Analysis of Real-time and Embedded systems (Half Day)

I'll be giving the DDS Tutorial along with Gerardo Pardo and the UML for DDS Tutorial with Sam Mancarella.

The second and third day of the Workshop, namely Tue 14th and Wed 15th, will be dedicated to paper presentations and the DDS Interoperability Demonstration.

If you want to see the full list of papers check out http://bit.ly/vcGCd I'll try to write up the most interesting things that will be happening.

Ciao!

Back from India

I spent the whole past week in India across Delhi and Banagalore giving several OpenSplice DDS presentations. I've always been extremely fascinated by India, when I was a kid it was for me the land of mystery, the land in which people could do amazing things; while growing as a teenager I was fascinated by philosophy at the foundation of Hinduism and Buddhism--yet, for one reason or another, I had not yet been in India. This first visit in India was fantastic from all perspective. From a technical perspective OpenSplice DDS presentations were very well attended by an extremely bright audience, which was also one of the most lively and inquisitive I've encountered in years. From a human perspective the experience was very enriching as I had a chance to live and breath the peacefulness and loyalty irradiating from most of the people I met. Thus, once again I'd like to thank all the people that took the time to come and listen to my presentations, that showed me around, and helped me in understanding more about this very fascinating country.

Namaskar,

OpenSplice DDS v4.1 Open Source - What's coming up?

Although I am sure that the Open Source release of OpenSplice DDS was noticed by most of you I am equally sure that many of you are wondering what is going to come next. I've discussed the content of the upcoming "source-drops" in my latest webcast, but perhaps it is worth sharing it on the blog as well. 

Before going into the details of what will be available next and when it will be available, it might be worth to spend a few words on the version numbering scheme we are using for the OpenSplice DDS Community edition. The version numbering will be pretty straightforward and will be made of MAJOR.MINOR.YYMMDD where MAJOR is the major version, MINOR (always>0) is the minor version and YYMMDD is the date for the beta incremental release.

Thus as an example the current version is v4.1 is the first v4 major release (notice that MINOR is never 0). The next release will be as follows:

v4.1.090526

• DDSI/RTPS [beta]
• Visual Configuration Tool
• mmstat (shared memory tool)
• Support for Windows 
• Support for Visual Studio Express 2005

v4.1.090626

• Unicast Communication for OpenSplice DDS Native Networking
• C# API [beta]
• Linux 64bit support

v4.1.09.07.31

• C# API 

Thus as you can see there are a lot of goodies coming up in the next few months.

The UML Profile for DDS goes Live!

This week, after circa 6 month from when the OMG recommended the UML Profile for DDS (UML4DDS), Sparx has made available a full implementation of this profile. This is a great news for all DDS users; now they have access to a great and affordable tool which will allow them to completely model DDS applications in UML. What I believe users will find fantastic is how the UML4DDS and the Sparx EA Tool make it very natural to work with the DLRL layer of DDS (see previous posts on DLRL and Hibernate). Many users, by seeing the UML4DDS will eventually realize that DLRL is the most natural way of using DDS from Object Oriented Languages, and certainly the most natural way of modeling DDS applications in UML.

DDS Interoperability Demo at the DC OMG Meeting

The next 25th of March, at the Washington DC OMG Meeting, PrismTech, RTI, and TwinOaks, will demonstrate on-the-wire interoperability between their DDS implementations. This is an important step toward proving that OMG DDS compliant implementations can interoperate and yet exchange real-time data without loosing performance or QoS and without introducing single point of failures.
This capability is quite distinct especially when compared with other technologies such as JMS for which on-the-wire interoperability is not an option and for which interoperability has to be achieved by means of bridges that along with introducing performance overhead also introduce single point of failures--often not acceptable in business- and mission-critical applications.

BTW, at the upcoming OMG Meeting there will be also some interesting discussions around the C++ PSM for DDS and the Extensible and Dynamic Topic Types, thus one reason more to be there.
