FT-P5-VME Bus Multiprocessor BoardThe FT-P5-VME is a highly scalable, high performance computing subsystem based on Analog Devices ADSP-2106x SHARC (Super Harvard ARChitecture Computer). A single FT-P5 provides nearly one GFLOP performance in a desktop workstation environment. Interconnected using their PMC dataports, Alacron's FT-P5 serves as a node on a Myrinet System or Local Area Network and delivers high levels of performance for imaging, graphics, simulation, DSP, document processing, and pattern recognition applications.
FT-P5-VME Features
ADSP-2106x SHARC Processor ArrayThe FT-P5's compute engine is an scalable array of up to 8 ADSP-2106x processors, interconnected using Alacron's Dual-Ported Local Memory (DPLM) architecture. The DPLM design eliminates processor contention for off-chip memory, allowing the memory bandwidth of the SHARC array to scale linearly with the number of SHARC processors. A two-dimensional DMA engine isolates the SHARC array from the system bus, shielding it from the impact of system bus traffic and data movement. In Single Instruction Multiple Data (SIMD) mode, Alacron's application libraries distribute processing tasks over several processors. All processors can access their private RAM banks simultaneously at 80 MB/sec. In Multiple Instruction Multiple Data (MIMD) mode, tasks are distributed to individual processors, with Alacron's RT operating environment controlling multiple threads. Pentium P5 Control ProcessorThe Ft-P5's performance is maximized by employing a Pentium P5 control processor to perform all operating system functions, thereby off-loading the ADSP-2106x processor array for data processing. The P5 supports multitasking operating systems and provides sophisticated memory management. PMC DataportsPMC dataports provide the FT-P5 with tremendous I/O and expansions capabilities. These dataports are compatible with all standard PMC cards. Myrinet ConnectivityPMC dataports allow the FT-P5's ADSP-2106x processors to DMA directly to the Myrinet, providing full duplex communication in excess of 1 GB/sec. In this manner, FT-P5s can be employed in in-cabinet clusters connected by a Myrinet System-Area Network (SAN) or serve as compute nodes in large distributed systems connected by a Myrinet LAN's. PerformanceThe FT-P5 series offers excellent performance for compute intensive algorithms. Representative performance of a single FT-P5 with from 1 to 8 ADSP-2106x processors on specific SIMD algorithms from Alacron's libraries are shown:
