JUBL

Called JUBL, or Juelich Blue Gene/L, the system offers a peak performance of 45.8 teraflops, equivalent to 45.8 trillion operations per second.

JUBL will serve as a "virtual laboratory" where scientists do environmental research work, such as simulating the diffusion of harmful materials in the atmosphere. It will also be used for the material and life sciences.

JUBL has 2,048 processors in each of its eight racks, for a total of 16,348. The older JUMP machine has 32 processors in each of 41 racks, for a total of 1,312 processors. The Blue Gene system also occupies less floor space -- about 100 square meters, compared to 300 to 400 square meters for the p690 system.
