The key addition was the concept of a cluster, CLU's type extension system and the root of the language's name (CLUster). [10] Clusters correspond generally to the concept of a "class" in an OO language. For instance, here is the CLU syntax for a cluster that implements complex numbers: complex_number = cluster is add, subtract, multiply, ...
The channel is the endpoint for joining a cluster. Next, the receiver is set, which means that two callbacks will be invoked: viewAccepted (View view) when a new member joins, or an existing member leaves the cluster; receive (Message msg) when a message from some other cluster member is received; Then, the channel joins cluster "ChatCluster".
Jakarta Connectors (JCA; formerly known as Java EE Connector Architecture and J2EE Connector Architecture) are a set of Java programming language tools designed for connecting application servers and enterprise information systems (EIS) as a part of enterprise application integration (EAI). While JDBC is specifically used to establish ...
Systems Network Architecture [1] (SNA) is IBM's proprietary networking architecture, created in 1974. [2] It is a complete protocol stack for interconnecting computers and their resources. SNA describes formats and protocols but, in itself, is not a piece of software.
The IBM Roadrunner cluster supercomputer. Specific tools may be used to simulate and understand the performance of message passing on computer clusters. For instance, CLUSTERSIM uses a Java-based visual environment for discrete-event simulation. In this approach computed nodes and network topology is visually modeled.
Hadoop: Java software framework that supports data intensive distributed applications; HAWQ: advanced enterprise SQL on Hadoop analytic engine; HBase: Apache HBase software is the Hadoop database. Think of it as a distributed, scalable, big data store; Helix: a cluster management framework for partitioned and replicated distributed resources
Many computer protocols, such as telnet, include a NOP command that a client can issue to request a response from the server without requesting any other actions. Such a command can be used to ensure the connection is still alive or that the server is responsive. A NOOP command is part of the following protocols (this is a partial list): telnet ...
This is an index to notable programming languages, in current or historical use. Dialects of BASIC, esoteric programming languages, and markup languages are not included. A programming language does not need to be imperative or Turing-complete, but must be executable and so does not include markup languages such as HTML or XML, but does include domain-specific languages such as SQL and its ...
