The Aoyama+ Project

- AGU's Beowulf-Style Parallel Computer Systems

System A: ARK

Product run machine used for massive parallel computations for many body problems in statistical and condensed matter physics.

69 Dual = 138 Pentium II (350MHz) processors.

1 NFS/NIS/Gateway host, 4 Boot servers,
64 Diskless clients.
256Mbytes memory each = total 17 GBytes.
peak speed = 50GFlops.
cost per CPU less than 95,000-yen ( approx $850).
total consumption of electric power: 3KW.

System X: XIAN

Introduced for evaluation of PC's performance, Linux+MPI system stability and Switching hub speed. Now used as a test-bed for new releases of Linux/Compilers/Parallel libraries.

4 Celeron 300A (450MHz) processors.
128 Mbyte memory each.
4GB disk each, bootable from both disk and net.

System B: BERN

Introduced for evaluation of Alpha-CPU's performance. Now used as a sub-system for massive computations.

10 Alpha 21164 (600MHz) + 2 Alpha 21264 (533MHz) processors.
512Mbyte x 10 + 1Gbyte x 2 memories
40GB RAID 5 disk with tape backup.

System C: CLUMP

The purpose of this system is to make an EASY-TO-INSTALL and EASY-TO-MAINTAIN system. Alinka-LCM system enables us to make an automatic setup for everything. Asselbled on-the-shelf , it's easy to get in touch with each Motherboard/CPU/memories' conditions.

11 Dual = 22 Cerelon 533MHz processors.
128Mbyte memory.
alinka-LCM system for automatic net-boot setups.
wake up on LAN boot.
compact size to save space.

System D: (coming soon)

System E: EDEN

"E" stands for "economical". Assembled from bare-bone kits, the total cost is less than 400,000-yen (approx $3600) for 8 CPU + Hub.

8 Cerelon 500MHz processors.
128Mbyte memory.
On-board 100Base-T connection.
Bookshelf size to save space.

System F:

28 Notebook PC , originally purchased as equipments for the experimental course of undergraduate students, are used as parallel computing machines when off duty.

28 Compaq Armada V300 with MobileCerelon 500MHz processors.
128Mbyte memory.
On-board 100Base-T connection.
