SPADE
is a scalable parallel architecture with support to
NORMA, CC-NUMA, COMA models. It's based on commodity
single/multiple CPU processing elements (Servers,
Workstations. High-end PC's) and commodity
interconnection networks (FastEthernet, ATM, SCI,
Myrinet). In order to provide efficient implementation
of shared memory model, as well as fast message passing,
we are developing custom interconnection systems with
hardware support for remote memory access. Two versions
of these interconnection systems are being developed: |
|
Interconnection
network based on PCI network adapter with remote memory
access capability; 8 ports Switch with multicast
capability; and high speed 66 MBytes/s LVDS links with
parallel cables; |
|
Interconnection
network based on ATM standard but optimized for low
latency, high throughput, reliable delivery, multicast
and no cell loss flow control. |
|
Interconnection
network based on SCI standard with support to remote
memory access |
|
We
also are implementing several prototypes of clusters: |
|
 |
Efficient
support for message passing and shared memory |
|
Fast
message passing based on active messages and
user level access protocols: LSI-EPUSP FULL,
based on Berkeley VIA and NIST M-VIA. |
|
Operating
Systems: LINUX, Windows NT |
|
Software

|
Hardware
support for fast synchronization |
|
Version
1: Processing elements + standard LAN adapters
and switches (Fast Ethernet, ATM, Myrinet) |
|
Version
2: Processing elements + dedicated
interconnection systems |
