The computational servers

The cluster

Following the significant reduction in the cost of the hardware in recent years and in order to meet the needs of high performance computing and scalable algorithms, in 1999 the UMA adopted a cluster consisting of several interconnected PCs via a bi-processor standard network layer. This cluster consisting of 32 heterogeneous machines (three generations of machines) is renewed every third year thereby maintaining a degree of investment. Today, the UMA has 64 processors with 532 cores interconnected by a Gigabit network layer.

Our cluster is composed by:

The cluster now utilizes a Linux operating system which is relatively simple platform to implement thereby reducing the cost of administration.

UMA also has a GPGPU Machine:

Members and users

All UMA hardware resources are fully administered and managed by Christophe Mathulik.

The computational power of the cluster is notably implemented and used by the "Gravitational Dynamical Systems" team. In connection with this method of calculation, the UMA provides the infrastructure and parts of a third year course module at ENSTA which is devoted to distributed computing. These course material are implemented via projects on the cluster.
