High Performance Systems and Interconnects | ||||||||
| Changed: | ||||||||
| < < | Recent advances in interconnection technologies have made clustered systems built out of commodity components an attractive option for providing scalable computational and storage infrastructure in a cost-effective manner. Such systems comprise numerous hardware (processors, memory, peripheral buses, interconnect NICs, storage controllers and media) and software (embedded firmware, OS kernel, NIC and block device drivers, file systems, communication middleware, application libraries and software) components. Understanding the intricate interactions between them, streamlining their semantics and improving their performance is key to achieving good performance. | |||||||

gmblock | ||||||||
| Changed: | ||||||||
| < < | gmblock is an ongoing effort to implement efficient block-level storage sharing over modern processor- and DMA-enabled interconnects such as Myrinet. Its design focuses on the flow of data in a network block device system, aiming to improve the efficiency of remote block I/O operations by completely removing the CPU and main memory from the critical path. Data are pipelined, directly from the storage medium to the interconnect NIC and link, thus reducing the impact of network I/O on the locally executing processes. | |||||||
