NEW (feb 2002) : the new MPC/MPI cluster of workstations :
16 proc. 1GHz, 8 Gb RAM, 1/3 To disk - Now available online !

This new cluster is specifically designed to run MPI jobs in a high parallel environment.
You can now launch your MPI jobs on our MPC machine. You can find more informations about this here (in french).
historical : the first MPC Parallel Machine that was available online
The MPC Parallel Computer of LIP6 laboratory was available online through a Job Management System.
You can now launch your PVM jobs on our MPC machine. You can find more informations about this here (in french).

What is MPC ?

MPC is a parallel computer. Our project goal is to design a high performance/low cost multiprocessor, using standard Pentium based PC-boards as nodes, Unix FreeBSD operating system, and a high speed communication network built on the gigabit-HSL (High Speed Link) IEEE-1355 technology.

Hardware Components

The high speed network is based on the RCube dynamic router, developed at UPMC/LIP6. RCube is a VLSI circuit implementing a 8x8 crossbar with interval labeling and wormhole routing. Each processor node is connected to a router by means of another dedicated chip, PCIDDC, implementing a Direct Deposit Protocol to provide inter-node DMA throw the PCI bus. A new programmable PCI interface chip, NOE, is under development.

Software Components

A stack of kernel protocols and monitoring daemons has been developed in cooperation with PRiSM and ENST laboratories, and integrated inside Unix FreeBSD to provide several communication layers for developpers. An optimized implementation of PVM on top of this stack is now available.
