2008 Lecture Notes in Computer Science  
Consequently, protocol stacks such as iWARP and MX for 10-Gigabit Ethernet and QLogic InfiniBand, utilize hybrid hardwaresoftware designs that take advantage of the processing power of multicore processors  ...  However, upper-layer stacks on these networks, such as the Sockets Direct Protocol (SDP), have not kept pace with such shift in paradigm, and have continued to assume complete hardware offload, leading  ...  For example, existing implementations of high-performance sockets on highspeed networks, such as the Sockets Direct Protocol (SDP) [10] over Infini-Band (IB) [24] and 10-Gigabit Ethernet (10GE) iWARP  ...

of commodity 10G Ethernet network adapters.  ...  It has been well studied that reliable multicast enables consistency protocols, including Byzantine Fault Tolerant protocols, for distributed systems.  ...  Furthermore, due to the standard protocol stack implementation on the Linux platform, the kernel would allocate socket buffer for each ethernet frame received and copy payload from kernel space to user  ...

Afterwards, these insights are utilized to map the LNET protocol semantics onto the Extoll networking technology. The result is a fully functional Lustre network driver for Extoll.  ...  First, a comprehensive analysis of the Lustre networking protocol semantics and interfaces is presented.  ...  IP over Sockets Direct Protocol The Sockets Direct Protocol (SDP) [137] , included as an annex of the Infiniband specification, was a first attempt to implement a transportagnostic protocol to support  ...
