The GCel uses T805 transputer CPU's at a clockspeed of MHz. Each transputer has a peak performance of MFlops and a LINPACK 100x100 performance of MFlops. The GCel of the 2 has MB memory per node. The communication between processors has a sustained performance of MB/s. The GCel runs under PARIX 1.2 and uses the ACE Fortran compiler and 2's version of the MPI libraries.
