Rationale
-
-
why and how is this work relevant?
-

Massively Multiplayer Online Games (MMOGs) have recently emerged as a novel Internet-based entertainment application. Hundreds of MMOGs already serve tens of millions of paying customers world-wide, with virtual worlds such as World of Warcraft and Runescape hosting daily several millions of players. These players want fast-paced entertainment delivered through the Internet, which raises important content and resource requirements; when these are not met in full and on time, players will quit. However, the current industry approach in addressing these requirements has high cost and limited scalability. The high cost makes the market inaccessible for amateur and small game developers. The limited scalability means that even the largest game developers cannot support this rapidly growing community. We aim to investigate scalable, dependable, yet low-cost computational technologies for MMOGs.

Recently, a social component was added to MMOGs---Massively Social Gaming defines MMOGs in which the social interaction between players enhances and extends the gameplay experience, not the least through emergent behavior. We aim to investigate the social component of MMOGs, and to understand how to leverage it to make the lives of MMOG players better.

As a third main goal, we would like to better integrate gaming into education (for a complex set of reasons that include but go beyond this rationale).

Our work has numerous domains of applicationi, including gamification, that is, the use of social gaming elements in the design and delivery of undergraduate or graduate courses. The emergence of gamification has prompted us to not only develop gaming technology, but also, education professionals, try to assess its effects on educating students of technical higher education. We have started this work in 2003 and, after a hiatus in terms of research between 2005 and 2011, started to disseminate our results from 2012 onwards--the latency of education research is much higher than that of computer science research.

Main Research Questions
-
-
what do we try to achieve?
-
  1. What are the characteristics of real MMOG workloads? Much effort has been put into characterizing the workloads of MMO Role Playing Games, a popular branch of MMOGs. However, many questions remain unanswered before the characterization is complete. What are the differences between MMOGs and other Internet-based applications? What are the characteristics of different types of MMOGs?
     
  2. How to evaluate the performance of a system, algorithm,  or mechanism designed for MMOGs? A major impediment to developing the area of MMOGs is the lack of an accepted method to evaluate the impact of new findings in system, algorithm, and mechanism design. How to evaluate the performance of MMOGs using simulations? Or real system experiments? Or analytical models?
     
  3. What are the characteristics of the social networks present in MMOGs?  While researchers have investigated the structure of (social) networks for decades, the activity characteristics and the community structure of online social gaming remain relatively unknown. What are the unique characteristics of the MMOG community? What characteristics do MMOG communities share with traditional (online) communities such as FaceBook, Youtube, Microsoft Messenger, and Flickr?
     
  4. Can MMOGs make use of clouds? As a consequence of their internal organization or of the policies of existing data centers towards hosting MMOGs, many MMOG operators have to maintain large computing infrastructures, either self-owned or leased over long periods of time. A possible alternative is to use resources and services provisioned from commercial clouds, perhaps as a complement to existing infrastructure and services. But which MMOGs can now leverage cloud infrastructure and platform services? Can MMOGs function well under the availability and performance profiles of the current production cloud services? Can we improve the MMOG analytics to MMOG social analysis?
     
  5. Can gamification, that is, the use of social gaming elements in the design and delivery of undergraduate or graduate courses, be effective in teaching higher-education courses?  Technical higher education, in Europe and many other world-regions, is at a crossroads. The pace and complexity of technological progress, economic pressure, and cultural changes over the past century have increased the societal and economic need for a well-educated body of technical-university graduates. However much already applied, for example to engage university students in a limited setting, gamification is not easy to apply to a new topic. For example, giving students points may foster competition and incentivize them to study harder, but it may also diminish their intrinsic motivation and (when points are not well balanced) make them feel discriminated against. The vast array of gaming elements available to designers, the loose theories of fun, and the contradictory evidence regarding the use of gamification in practice, make applying gamification in higher education a challenging task.
     

 


Main Achievements
-
-
what did we do?
-
  1. Collected input to characterize the workloads of several real MMOGs. We have collected long-term traces that can be used to characterize the workloads of several real MMOGs. We have already used [1,7] one such trace to uncover the interaction between players as a major strain to the system; this was ignored in previous work on MMOG workloads, and also helps distinguishing MMOGs from well-studied Internet-based applications such as Web servers.
     
  2. Designed CAMEO, a framework for continuous analytics for massively multiplayer online games (MMOGs) using cloud resources. We have provided [4] a first estimate of the feasibility and costs of performing continuous analytics for MMOGs on cloud resources.
     
  3. Within edutain@grid, analyzed the feasibility of running massively multiplayer online games (MMOGs) on cloud resources. We have analyzed [1,7] the potential gains of running MMOGs on cloud resources, based on an ideal cloud/data center model. We have started to investigate [5] the impact of virtualization on running MMOGs on cloud resources.
     
  4. Analyzed several aspects of the social component for the BBO / BBO Fans online bridge communities. We have analyzed [11] the community structure and the ability of the community to coordinate its activity (self-organization, synchronization) among tens of thousands of players.
     
  5. Designed a gamification strategy for technical higher education. We have presented [26] this design and aanalyzed its impact in two courses, spanning 4 operational years and contributing to the education of over 450 students.
     

 


Main Findings
-
-
what did we find?
-
  1. "It is possible to automatically generate at massive scale puzzle instances of commercial quality on grid infrastructure." [6][7]
     
  2. "Otherwise unused (spare) resources may be used to solve complex puzzle instances at almost zero cost and with reduced overhead, if appropriate resource allocation policies are used." [3]
     
  3. "The performance of the production cloud services offered by Amazon Web Services and Google App Engine varies over time, and can alter significantly the performance and cost profiles of large-scale applications such as social gaming (state management, trading virtual goods, etc.)." [9]
     
  4. "Continuous analytics for MMOGs on cloud resources is feasible and shows good promise of being cost-effective." [4][13]
     
  5. "Dynamic resource allocation from clouds can lead to a tenfold reduction of the platform operation costs for massively multiplayer online games (MMOGs)." [1][7]
     
  6. "Games can be used as and are a good vehicle for teaching the principles of Software Engineering, provided the curriculum uses the appropriate games for teaching the right topics." [1]
     
  7. "Without adequate resource virtualization policies, the performance limitations threaten to cancel out the benefits of resource virtualization." [5][10]
     
  8. "For online bridge, the following player behavior type are common: community builder, community member, random player, faithful player. Moreover, online bridge communties are coordinated (self-organized, synchronized) even for large numbers of players (tens of thousands). " [11][12]
     
  9. "From an empirical evaluation using three years of experience with an undergraduate course and one year with a graduate course, during which we have educated over 450 students, we have found that gamification can help in many ways our students, from increasing passing rates and participation, to high student satisfaction and touching testimonials." [26]

  info (Improved version of our SC|08 article) We have investigated a new dynamic resource provisioning method for MMOG operation using external data centres as low-cost resource providers. We have introduced a comprehensive MMOG load model that takes into account both the player interaction type and the population size. We have assessed using trace-based simulation the impact of the data centre policies on the quality of resource provisioning. Last, we have presented experimental results showing the real-time parallelization and load balancing of a real game prototype using data centre resources provisioned using our method and show its advantage against a typical client threshold approach.

  info (Extended version of EuroPar 2009 article) In this work we have investigated the automated puzzle game content generation for MMOGs on grid infrastructures. First, we have characterized the requirements of this novel grid application. With long-term real traces taken from a popular MMOG we have shown that hundreds of thousands of players are simultaneously online during peak periods, which makes content generation a large- scale compute-intensive problem. Second, we have designed the POGGI architecture, which focuses on large-scale generation of puzzle instances that match well the solving ability of the players, and that lead to fresh playing experience. We assess the performance of our reference implementation in a real pool of over 1,600 computing nodes, and demonstrate that POGGI can generate commercial-quality content efficiently and robustly.

  info We are the first to identify the problem of the scalability of game content generation. To address this problem, we have designed an implemented POGGI, an architecture for automatic and dynamic content generation for MMOGs. Our architecture focuses on puzzle game content generation, which is one of the most important components of the generic game content generation problem. Experimental results in a large resource pool show that our approach can achieve and even exceed the manual generation of commercial content.
