It is meant for codes that scale well into hundreds or even thousands of processors.
So, unless your code scales well and so can benefit from using a lot of processors, you may be better off running it with fewer processors on e. The 18 racks are arranged in six 6 rows with three 3 racks each making up a 48x24x16 3D torus.
The first rack on the first row row 0 is designated as R00, while the third one on the sixth row row 5 is R New York Blue is subdivided into partitions a. Each partition has a specific size number of nodes , type Mesh or Torus , and pset ratio one of the ratios mentioned above. Partitions can be predefined or created by users dynamically according to their job needs. A complete list of predefined partitions and naming conventions can be found in the User's Guide.
The pset ratio varies throughout the machine, having one of the four pset ratios mentioned above.
There are compute nodes on a midplane. Users compile their application codes and submit their jobs on the FEN.
The name Blue Gene comes from what it was originally designed to do, help biologists understand the processes of protein folding and gene development. The "P" version was designed to be a petascale design.
The two CPUs were not cache coherent with one another. With so many nodes, component failures were inevitable. The system was able to electrically isolate faulty components, down to a granularity of half a rack compute nodes , to allow the machine to continue to run.
Finally, a separate and private Ethernet network provided access to any node for configuration, booting and diagnostics. The program was then loaded and run on all the nodes within the partition, and no other program could access nodes within the partition while it was in use.
Upon completion, the partition nodes were released for future programs to use. Only a subset of POSIX calls was supported, and only one process could run at a time on node in co-processor mode—or one process per CPU in virtual mode. Programmers needed to implement green threads in order to simulate local concurrency. However, some scripting languages such as Ruby  and Python  have been ported to the compute nodes.
The cores are cache coherent and the chip can operate as a 4-way symmetric multiprocessor SMP.
The memory subsystem on the chip consists of small private L2 caches, a central shared 8 MB L3 cache, and dual DDR2 memory controllers. A single compute node has a peak performance of A rack contains 32 node boards thus nodes, processor cores. The bit A2 processor cores are 4-way simultaneously multithreaded , and run at 1.
The 18th core is used as a redundant spare, used to increase manufacturing yield. The spared-out core is shut down in functional operation. The L2 cache is multi-versioned, supporting transactional memory and speculative execution , and has hardware support for atomic operations.
It delivers a peak performance of A Q32  compute drawer contains 32 compute cards, each water cooled. Beyond the midplane level, all connections are optical.

Racks have two midplanes, thus 32 compute drawers, for a total of compute nodes, 16, user cores and 16 TB RAM. The same 4-rack system achieved the top position in the Graph list  with over GTEPS giga traversed edges per second.
