....throughput. Then, those workloads should be used to profile execution times and to derive partitions. 8. RELATED WORK Many researchers have used programmable network interfaces to implement user level protocols directly in network interfaces or to analyze performance issues in network servers [4, 5, 12, 15]. Shivam et al. implemented a parallelized version of their own Ethernet Message Passing (EMP) protocol on the Tigon [15] EMP is a specialized message passing protocol for clusters, designed to provide a low latency and high bandwidth message passing system that is based on user level access to ....

....messages (much greater than standard Ethernet frames) the authors were able to achieve nearGigabit rates on relatively slow machines. Buonadonna and Culler developed Queue Pair IP, which replaces the traditional socket abstraction in order to reduce networking overhead for system area networks [4]. Queue Pair IP uses the existing Internet protocols as its transport layer, and the prototype implements components of TCP IP directly in the LANai adapter. The authors show that Queue Pair IP can reduce load on CPU while providing lower latency and higher bandwidth than either Gigabit Ethernet ....

....network interfaces to reduce the processing requirement on the host processor to communicate with the network. Examples include checksum offloading, support for zero copy I O and user level protocol processing, as well as partial implementations of network protocols on the network interface [9, 16, 20, 34]. Checksum offloading moves checksum computation for network protocols such as TCP IP from the host processor to the network interface, thereby reducing expensive data touching operations that a number of researchers have identified as a potential bottleneck [11, 13, 19] Virtually all modern ....

....compete for a single NIC, an application that requires low latency can avoid congestion through the use of virtual interfaces. Buonadonna and Culler developed Queue Pair IP, which replaces the traditional socket abstraction in order to reduce networking overhead for system area networks [9]. Queue Pair IP uses the existing Internet protocols as its transport layer, and the prototype implements components of TCP IP directly in the LANai adapter. The host processor no longer handles TCP IP protocols, thereby reducing load on the processor. The authors show that the Queue Pair IP ....

....network interfaces to improve the performance of application level networking in other contexts. For example, Buonadonna and Culler provide a low latency nonsocket interface for communication in system area networks by offloading a subset of the network stack to a Myrinet LANai 9 network interface [5]. Krishnamurthy et al. use I2O network interfaces with i960 processors to control disks and stream data directly from disk to the network without using the host CPU, PCI bus, or main memory [10] Petrini et al. use the Elan network interface to provide a single address space and implement the MPI ....

....of functionality for a server system under real server application workloads. CSP also does not explore the issue of providing a programming interface which allows server applications to exploit performance gains from using an efficient low latency memory mapped communication layer. QPIP [11] is an attempt to provide a lightweight protocol for applications which offloads network processing to the Network Interface Card (NIC) However, they implement only a subset of TCP IP on the NIC. QPIP suggests an alternate interface to the traditional sockets API but does not define a programming ....

....(NIC) However, they implement only a subset of TCP IP on the NIC. QPIP suggests an alternate interface to the traditional sockets API but does not define a programming interface that can be exploited by applications to achieve better performance. Moreover, performance evaluation presented in [11] was limited to communication between QP aware applications over a SAN. Sockets Direct Protocol (SDP) 44] originally developed to support server clustering applications over VI architecture, has been adopted as part of the InfiniBand specification. The SDP interface makes use of InfiniBand ....
