The MOAIS/Kaapi team participated in the Grid Plugtests in 2007 and 2008.

The Grid Plugtests consist in developing a distributed application to solve a complex problem using a grid. Deployment and computation are limited to one hour. The purpose is to test and improve interoperability mechanisms of grid middleware.

The IVth Grid Plugtests hold in Beijing, China from 29 October to 1st November 2007. The Challenge was to count the solution number of the N-Queens problem (rules).

- Xavier Besseron (integration of TakTuk with ProActive)
- Vincent Danjean (karun)
- Guillaume Huard (TakTuk)
- Serge Guelton (N-Queens program)
- Frédéric Wagner (N-Queens program)
- Thierry Gautier (Kaapi, leader)

- Deployment of 3654 cores of Grid'5000 last less than few minutes
- N-Queens N=22 solved in 3min 21s on 3654 cores of Grid'5000
- N-Queens N=23 solved in 35min 7s on 3654 cores of Grid'5000
- First prize, winner of the N-Queens contest

The Vth Grid Plugtests hold in Sophia Antipolis, France from 20 October to 23 October 2008. The Challenge was to price high dimensional European options (rules).

- Xavier Besseron (sequential code for option pricing using Monte-Carlo)
- Guillaume Huard (deployment tools for GCM standard)
- Thierry Gautier (parallelization of the Monte-Carlo code)
- Emmanuel Gobet (expert for the mathematics of the problem)

- Conjoint deployment on Grid'5000 (French grid) and Intrigger (Japanese grid)
- A single application running on 3609 cores of the both grids
- The application has tolerated 2 software faults
- 0.9 x 10^15 Monte-Carlo simulations in one hour
- 96% of time spend in computation
- First prize, winner of the contest
