MOSES: the US Army’s OpenSim exercise

On Friday 23rd September, Nonprofit Commons (NPC) hosted a presentation by Douglas Maxwell, Science and Technology Manager for Virtual World Strategic Applications at the U.S. Army Simulation & Training Technology Center (STTC), who was speaking at Plush Nonprofit Commons in Second Life.

He was there to specifically discuss MOSES – the Military Open Simulator Enterprise Strategy – although his talk broadened to covered other aspects of the STTC’s work.

MOSES is a project aimed at evaluating the use of OpenSim as a means of providing a virtual world-based simulations and research environment available for use by relevant parties both within and without the U.S. Department of Defense. It grew directly out of the STTC’s involvement with the Second Life Enterprise product.

STTC

Currently overseen by Colonel Craig G. Langhauser, the STTC – Full name, the SFC Paul Ray Smith Simulations Training and Technology Center, in memory of posthumous Medal of Honor recipient Sergeant First Class Paul Ray Smith, killed in 2003 during Operation Iraqi Freedom – was officially founded in 2002, with a heritage stretching back over the last two decades related to the use of simulator-based training technologies. Located in Orlando, Florida, the unit’s stated mission is to: Enhance Warfighter readiness through research and development of applied simulation technologies for learning, training, testing and mission rehearsal.

As the Science and Technology Manager at STTC, Douglas Maxwell (SL name: Maccus McCullough) is no stranger to the use of computer simulations, having started out in the mid-1990s, when he was hired by the US Navy as a civilian specialist to work in their Virtual Reality labs in Washington DC. It was there that he realised people were becoming more immersed in simulations, “It isn’t logical to duck when a virtual object is flying at you, but they did,” he explained to the audience at the presentation.

“It told me they had made the mental leap from reality into the virtual environment we created. So I started looking at gaming technologies,” he continued. “[And then] a wonderful thing happened in the late 90’s. nVidia released the first commercially available and cost-effective PC based 3D graphics accelerators. We no longer needed a $750k SGI computer to do 3D tasks.”

This led Maxwell to write a paper how PC clusters could be used for simulation work at a much lower cost than that associated with high-end, dedicated systems, while also offering the same flexibility of use in creating and modifying scenarios. A paper which didn’t win him a popularity award, as he noted wryly to the audience, “I got some hate mail for that one!”.

Virtual Worlds and 3D Games

In 2008 Maxwell and his team started investigating virtual world environments as possible platforms for research, looking at OpenSim and Second Life. They immediately drawn to what they found in SL. “It is a computationally steerable persistent simulation,” Maxwell explained to his audience. “The capabilities in here are tremendous: in situ scripting, terrain deformation in real-time, every object is composable, not static. We got the idea that if we could increase the fidelity of the physics in here, it could actually be very useful”.

As a result of these explorations, Maxwell engaged with Linden Lab to address issues of security and data integrity for simulations, the company steering Maxwell’s team towards the Second Life Enterprise product. Simultaneously, he established the 12-sim Naval Underwater Warfare Center campus within Second Life itself – used more as a promotional tool than for simulation work.

Alongside of this, Maxwell and his team brought the source code rights to an entire commercial 3D gaming system which they used to develop EDGE-P – the Enhanced Dynamic Geosocial Environment Platform – an advanced virtual environment used to provide real-world operational environment training.

EDGE enables personnel from different locations to be brought together and trained in a wide range of scenarios, including homeland security and preparation for overseas posting. During his NPC presentation, Maxwell invited his audience to watch footage from an EDGE simulation held in September 2011, in which troops in one location were put through and immersive contact scenario with members of an Afghan village (represented by native language speakers located in other US Army bases). Observer / trainers were able to monitor proceedings from other centres, and provide exercise objectives and feedback for the participants.

The use of SLE covered a similar field of study, with the product being used to create aspects of the Afghanistan terrain for training and simulations study. Of particular interest to the team was a mix of the platform’s content creation capability and the ability to deform and model the terrain to suit their requirements combined with the fact that virtual worlds are entirely non-deterministic, or as Maxwell put it, “We set the goals, not the makers of the virtual world”.

When Linden Lab announced in May 2010 that they were pulling the plug on SLE, Maxwell faced a problem. Considerable time, effort and money had been put into developing a wide range of content and data using the SLE platform which he didn’t want his team to lose. As a result, he found himself once again looking at OpenSim – and receiving another surprise. “It had matured significantly since 2008. It was more stable, feature rich [and] even allowed for *gasp* backups!”

MOSES

Thus was born MOSES – the Military Open Simulator Enterprise Strategy – with the aim of evaluating whether OpenSim could in fact meet and exceed the capabilities originally being developed within the SLE product, with the goal of providing a persistent and stable virtual world incorporating VOIP, base content, mesh, media on a prim, and monitoring tools.

MOSES currently comprises some 117 regions running on standard OpenSim software and HP servers. Additionally, the team brought online assets from The University of Central Florida’s STOKES High Performance Computing Center, which allow them to run Intel’s Distributed Scene Graph (DSG). This in turn allows them to tun up to 1,000 avatars on super sims. The environment had its official debut at the U.S. Defense GameTech Users’ Conference, held in March 2011.

MOSES initially hosted the content originally created in SLE (safely exported prior to the licences expiring), which included some 36 sims modelling terrain common to Afghanistan. However, it quickly grew far beyond that. Some 18 sims have been assigned for use by the US Air Force and at least four for use by the US Navy. Nor does it end there.

This is because MOSES isn’t restricted to purely military uses. Indeed, unlike SLE, rather than sitting behind a hyper-secure firewall, it’s sitting on the open Internet. Maxwell cites two reasons for this.

The first is purely practical for the project: “MOSES is on the public Internet … to allow us all to expand, more efficiently, best practices in using Open Simulator and 3D Web virtual environments,” he said, talking to Sitearm Madonna about the work.

Safe Haven

The second reason is a little more philanthropic: Maxwell saw a need to offer a safe haven  for others in the same situation he’d found his team in with the loss of SLE.

“I knew of many users in the military, industry and academia who were in the same dilemma as myself – how do we preserve the content?” he explained to his NPC audience. Thus, MOSES provided a way for other groups and organisations to migrate their work.

To date, over 100 non-military accounts have been established on MOSES, either as a result of migration from SLE or because of individual requests for access to the platform. Regions have been supplied to research groups, organisations, and some private companies, some of which also have Estate Manager rights to the sims they use. “The academics really like it,” Maxwell observed, “As it provides a safe environment for their students.”

Nevertheless, on the open Internet it might be, but MOSES has security measures in place that equate to around 75% of the security achieved on the SLE platform, increasing its attractiveness to those engaged in research and development. It is certainly not for the hobbyist, as Maxwell made clear. “MOSES is a professional environment, and everyone is expected to maintain decorum. There are no casual users.”

Accounts can be obtained by visiting the MOSES website and registering interest. All requests are vetted by Maxwell himself in order to discover the level of interest, type of proposed use on the grid, and so on. While priority is obviously given to military projects, proposals don’t have to be within the military arena in order to gain access to the system. “If you’re developing or evolving some cool new kind of technology, like bots, for example, that would be clearly relevant to the MOSES mission,” Maxwell informed Sitearm.

While the STTC provide a dedicated Viewer (based on Imprudence) pre-set to point directly to MOSES, any TPV can actually be used to access the system once a request for use has been approved. To help with communications and to provide updates and information, Maxwell has adopted the LL approach of holding weekly in-world Office Hours meetings. These take place every Friday at 15:00 EDT, and he encourages those using the platform to attend; “The weekly office hours are a great way to meet open simulator developers and our team. We usually have 20-ish in attendance”.

There are some key points to remember when applying for access to MOSES, as Maxwell stated to Sitearm: “What you put on MOSES, you own free and clear,” he stated unequivocably. “We have also enabled full-sim backups from your MOSES regions to your own organisation’s hard drives.”

He also added, “It’s important to remember [that] MOSES is a research and development environment, not an operations environment. We will keep upgrading the platform, for example, as we learn new improvements in using OpenSim”.

Certainly, as a dedicated research environment enjoying the benefits of controlled access, MOSES offers significant attractions to those carrying out virtual world related research and study. The project itself stands, as Maxwell himself commented when talking with Sitearm Madonna, “As carrying on the tradition of military research contributing to the public good”.

  1. LL did not really close up shop on SLE. I believe the Navy bought the rights to the whole thing.

    So why is Maxwell squawking about being pushed out? Why couldn’t the Army gain rights to the platform from the Navy? They are, afterall, a military division for the same country.

    And why is my tax money going to this silliness?

    1. I’ve not heard anything about the US Navy “buying” the rights to SLE. As far as I’m aware, the SLE shut-down was an internal decision by Linden Lab. First I’ve ever heard of the USN (for whom Maxwell worked in simulations, etc., up until March of last year) having acquired it. Any citations relating to it?

        1. That looks to be an open solicitation to purchase 70 copies of SLE. Not sure that constitutes purchasing the rights to the whole thing.

  2. Thank you very much for the post and your interest in our work, Inara.

    There has been some controversy regarding that FBO solicitation and it being interpreted correctly. It was simply a support purchase spread out over 70 seats. -douglas

  3. Project MOSES is wrong. It is about continuity of government in a way that the only way it could be called upon to be needed is if a superpower used direct Military force on the USA……

    Put simply they are creating a solution to a problem that can’t exist except by them creating the problem, and then leaving the only solution to be using them as the answer…..

    This wouldn’t be the first time technology has been perverted by military…..
