A non-blocking socket returns whatever is in the receive buffer and immediately continues. If not written correctly, programs using non-blocking sockets are particularly susceptible to race conditions due to variances in network link speed. [citation needed] A socket is typically set to blocking or non-blocking mode using the functions fcntl ...
Non-blocking algorithms generally involve a series of read, read-modify-write, and write instructions in a carefully designed order. Optimizing compilers can aggressively re-arrange operations. Even when they don't, many modern CPUs often re-arrange such operations (they have a "weak consistency model "), unless a memory barrier is used to tell ...
A network socket is a software structure within a network node of a computer network that serves as an endpoint for sending and receiving data across the network. The structure and properties of a socket are defined by an application programming interface (API) for the networking architecture.
In computer science, message passing is a technique for invoking behavior (i.e., running a program) on a computer.The invoking program sends a message to a process (which may be an actor or object) and relies on that process and its supporting infrastructure to then select and run some appropriate code.
In distributed computing, a remote procedure call (RPC) is when a computer program causes a procedure (subroutine) to execute in a different address space (commonly on another computer on a shared computer network), which is written as if it were a normal (local) procedure call, without the programmer explicitly writing the details for the remote interaction.
Socket: Data sent over a network interface, either to a different process on the same computer or to another computer on the network. Stream-oriented (TCP; data written through a socket requires formatting to preserve message boundaries) or more rarely message-oriented (UDP, SCTP). Most operating systems Unix domain socket
HTTP pipelining is a feature of HTTP/1.1, which allows multiple HTTP requests to be sent over a single TCP connection without waiting for the corresponding responses. [1] HTTP/1.1 requires servers to respond to pipelined requests correctly, with non-pipelined but valid responses even if server does not support HTTP pipelining.
The Message Passing Interface (MPI) is a portable message-passing standard designed to function on parallel computing architectures. [1] The MPI standard defines the syntax and semantics of library routines that are useful to a wide range of users writing portable message-passing programs in C , C++ , and Fortran .
