....deallocation of resources [4, page 131] Smith and Williams [17] give an example of real time system performance engineering of a design which includes a second phase. Many existing distributed operating systems support second phase execution, including Ameoba [18] Chorus [16] V [2] and Sun RPC [4]. Second phase service is also directly supported in the programming language Ada [1] The two phases of service are illustrated in Figure 1. The time interval from the instant of the receive at the server to the time of the reply is described as phase one; the server execution after the reply, ....

....within a virtual processor (i.e. a UNIX process) can simply be done by copying data between the tasks address spaces, we need some form of global interprocess communication mechanism to implement communication and synchronization across the network. Possible alternatives include RPC packages [8], the TLI interface or socket primitives. For compatibility reasons, we chose the Berkeley socket interface to implement MMK X communication. The socket primitives are accessed through a software layer that provides the same functionality as the NX 2 operating system on the iPSC. This layer is ....

....the use of procedure calls to a distributed environment. RPC simplifies the development of distributed applications by abstracting details of communication, transmission errors, and failures. Its semantics are mostly those of an ordinary procedure call in many sequential programming language [46, 65]. A conventional procedure call transfers control to the sequence of instructions to the body of the procedure. When the procedure has been executed, control returns to the calling point. Usually a procedure returns a result. For input and output purposes parameters can be passed into the ....

While Java, ActiveX, and Javascript may be the most important technologies for client side computing, server side computing can be handled with CGI, Java RMI, CORBA [11, 9] and RPC [6]. With the system Progress [1, 3, 2] which we have developed, we follow similar aims like the above mentioned technologies for server side computing. But in contrast to these technologies where the main aim is to establish technological platforms for (server side oriented) distributed computing, ....

....A Java package is used (see [7] that completely hides the communication issues from the plan editor by providing methods for packing and unpacking the Progress data structures and for sending and receiving data via a socket connection to the remote Progress server. This package uses XDR (see [6]) to encode the data,because this is the way how the communication between Progress servers is handled. When loading a plan from the Progress server, the layout of the corresponding directed acyclic graph has to be determined. How should we place the nodes on the canvas of the graph drawing tool ....

The practicality of this approach is well recognized, and used as the basis for many experimental [3, 2, 9, 8] and commercial [6, 7, 17, 18] distributed systems. However, conventional RPC systems have a crucial restriction: only certain data types can be used as the arguments of a remote procedure. For example, pointers or higher order functions cannot be used directly as arguments. In ordinary programming languages, it is common for ....

....expected utilization (e.g. hallways) For better efficiency, the host serial line can be dedicated to a single base station, and the base station operates asynchronously: the base station forwards IR packets to the host as soon as they are received. Gateway processes on each host export a Sun RPC [2] interface for access to the base station. The RPC interface allows clients to send a packet unreliably over the infrared medium. When transceivers receive packets from the gateway they broadcast them into the infrared medium. The packets sent from the transceiver contain type, length, source ....

Distributed applications can also be developped with object technologies but this implies to manage communications between remote objects. Tools such as CORBA [GX92] RPC [Cor91] and Java RMI [SUN96] facilitate the communication implementation by hidding network accesses. Distributed applications are now needed in software developments, for example in domains such as Human Machine Communication and groupware to separate graphical development and functional core [RP95b, ....
