We exhibited Comet IP/OC48c(2.5Gbps) clustering technology
in Dallas at Super Computing 2000.
This cluster consists of
four PCs which mount the Comet network adapters connected
to OC48c POS switch. This Comet network adapter has the Comet NP/FPGA chip
and mounts a PMC standard OC48c network interface.
The key technology is "on-the-fly" processing of IP packets.
The Comet network adapter performs packet processing
while the packet is in the state of DMA. Compared with traditional
I2O network adapters with CPU,
there is an advantage that our method
shortens the time which IP packets are sent to and received from the
network.
Using PM/Comet and SCore-D software,
we demonstrate some parallel applications such as NAS Parallel Benchmark
and Ratracing CG software on this cluster. We also show the networking
performance of PM, UDP/IP and TCP/IP protocol.
At last, we have achieved TCP/IP processing performance is over 90MB/sec.

Comet prototype network adapter
We have aimed to manufacture the stream processor by the ASIC technology,
which does the protocol processing at very high speed.
This time, we developed the sream processor card equipped with FPGA chip
(Xilinx XCV1000) and DES engine chip (Fujitsu CG61394).
FPGA chip is equipped for the purpose of the increase of the circuit scale
and the operation speed improvement which can be made for trial purposes.
Moreover, DES engine chip was installed on this caed for the speed up of
the security function (IPSec) on the internet.
It is known that this technology is considerably heavy processing,
while it is indispensable function on the internet, and it is expected to
treat with hardware.
We confirmed to have the processing performance of 22MByte per second in
the IPSec communication as a result of this evaluation.
The next generation Comet NP/ASIC will be capable of the processing
performance of 88MByte per second.
We released a Comet board which meets standards of Compact PCI.
Currently, we put the electricity supply on this, and checked the basic
works with some checking programs.
For complete experiments, we are running DV/IP software program
with some networking cards mounted on this board.
Comet prototype was used in the opera of Ryuichi Sakamoto, 'LIFE'. 'LIFE' played on Sep 4-5 in Osaka, and Sep 9-12 in Tokyo, New York, and Frankfurt through high-speed internet. Our Comet Prototype has enabled such stable high-speed processing. Comet prototype supported for the digital video over internet protocol.
