A multipurpose, distributed MatLab calculations oriented, cluster machine was assembled in PERG/ELHEP laboratory at ISE/WUT. It is predicted mainly for advanced photonics and FPGA/DSP based systems design for Free Electron Laser. It will be used also for student projects for superconducting accelerator and FEL. Here we present one specific side of cluster design. For an intense, distributed daily work with the cluster, it is important to have a good interface and practical access to all machine resources. A complex management system was implemented in PERG laboratory. It helps all registered users to work using all necessary applications, communicate with other logged in people, check all the news and gather all necessary information about what is going on in the system, how it is utilized, etc. The system is also very practical for administrator purposes, it helps to keep controlling who is using the resources and for how long. It provides different privileges for different applications and many more. The system is introduced as a freeware, using open source code and can be modified by system operators or super-users who are interested in nonstandard system configuration.
The MOSIX Cluster project is an attempt to build a full functional cluster machine which consists of many different PC stations. The idea is to create a general purpose structure, which will be used for many different projects and calculations. Our machine is a heterogeneous system (consists of nodes with many different architectures), which makes it very interesting during the testing phase. It is tested with OBCA tasks, which need quick connection between nodes and often make such operations like reading and writing to disk. Many comparisons of efficiency are made during testing and
calculations.
