Merlin 500 PowerPC Daughtercard

Merlin Based on the advanced MPC7410 PowerPC™ with AltiVec™ technology, the Merlin 500 compute daughtercard delivers up to 16 GFLOPS of processing performance in a single 6" x 6" board for the most demanding applications. With SKY Computers' architecture Merlin 500 is configured on 6U and 9U boards and easily integrated into high performance computing systems.

Merlin 500 capitalizes on the new AltiVec technology-based 500 MHz MPC7410 PowerPC by supporting high-speed processing with both high-speed memory and high-speed communication. SKY has implemented the 250 MHz level 2 cache in the MPC7410 to provide developers with both high performance compute and the I/O power to maximize total computational throughput.

The communication interconnect between Merlin 500 boards, chassis, and systems is provided by the ANSI standard SKYchannel 320 MB/sec packet bus architecture. Multiple simultaneous SKYchannel connections facilitate fast communication throughout the system hierarchy to continually provide maximum throughput. The SKYchannel communications back bone provides high speed communication and fast data transfer performance while maintaining the programming ease of a 16 terabyte shared memory architecture.

The SKYvec® development tools simplify code development for large multiprocessor systems by automating many of the processes which otherwise would have to be designed or managed by the programmer. SKYvec eliminates the need for time consuming and costly software ports, training classes, and on-site vendor support by making development easier than ever before.

6U VME Board

Merlin is available for SKY Computers' 6U and 9U VME boards and the HPC computer systems. Merlin uses four 500 MHz MPC7410 PowerPC processors configured in a cluster on each daughtercard to provide up to 16 GFLOPS of performance. Each MPC7410 has its own local bank of 64, 128 or 256 MB of SDRAM that is accessed over the processor's 83.3 MHz local memory bus at 667 MB/sec. The memory of other processors on the daughtercard can also be accessed over the 667 MB/sec local bus. Global memory and memory on other daughtercards is accessible through the 320 MB/sec SKYchannel interface.

The MPC7410 processors are directly connected to a 64-bit SKYchannel motherboard interface. A DMA engine in the SKYchannel interface enables computing to occur concurrently with the transfer of data anywhere in the 16 Terabyte memory-mapped SKYchannel address space. The application developer can choose between memory mapped access or advanced DMA access to shared memory with equally efficient SKYchannel access.

Multiprocessor Software
The advanced capabilities of the SKYvec® Software Development Environment, make Merlin 100% compatible with earlier generations of SKY products. A simple recompile and run accesses all of the new capabilities of the new Merlin. Migration from other vendors' platforms is nearly as easy.

Merlin makes full use of SKYvec, including intelligent compiler technology that automatically optimizes and vectorizes application code. The SKY Standard Math Library contains several hundred math, image, and signal processing functions. SKY/VSIPL simplifies multiprocessor development and ensures portability across platforms. The TimeTrac Multiprocessor Event Analyzer provides insight into the dynamic interactions between processors for multiprocessor optimization and debugging.

Technical Support and Warranty Programs
SKY's commitment to quality begins with the industry's longest standard hardware warranty. All SKY hardware products, including the Merlin, have a standard one year warranty. Throughout your development and deployment, SKY's experienced technical support engineers follow up with the support you need when you need it.
