Computation expressions in F# provide a convenient syntax for writing computations that can be sequenced and combined using control flow constructs and bindings. They can be used to provide a convenient syntax for monads, a functional programming feature that can be used to manage data, control, and side effects in functional programs. Sequence expressions are an example of a computation expression, as are asynchronous workflows and query expressions. For more information, see,, and.
Computation Expressions F Microsoft Docs
Certain features are common to both sequence expressions and asynchronous workflows and illustrate the basic syntax for a computation expression: The previous syntax specifies that the given expression is a computation expression of a type specified by builder-name. The computation expression can be a built-in workflow, such as seq or async, or it can be something you define. The builder-name is the identifier for an instance of a special type known as the builder type. The builder type is a class type that defines special methods that govern the way the fragments of the computation expression are combined, that is, code that controls how the expression executes. Another way to describe a builder class is to say that it enables you to customize the operation of many F# constructs, such as loops and bindings.
In computation expressions, two forms are available for some common language constructs. You can invoke the variant constructs by using a! (bang) suffix on certain keywords, such as let! , do! , and so on. These special forms cause certain functions defined in the builder class to replace the ordinary built-in behavior of these operations.
These forms resemble the yield! Form of the yield keyword that is used in sequence expressions. For more information, see.

Researcher Dr David Kainer is using the NCI supercomputer to look into Eucalypt genomes and understand how specific kinds of Eucalyptus Oil are produced. Mr James Goldie from the ARC Centre of Excellence for Climate Extremes models hot weather days and how they impact on health outcomes for Australians. The NCI Board has welcomed the Australian Government’s announcement that it will invest $75 million to replace Australia’s highest performance research supercomputer, Raijin, which is rapidly nearing the end of its service life. Dr Sophie Calabretto from Macquarie University uses the NCI supercomputer’s tremendous computational power to work through equations that generate a high-resolution view of the intricacies of interacting fluids. The objective of HydroAsia is to promote, in a global Asian vision, the key concepts, methodologies, tools and good practices which are essential for a sustainable water management. Today, problems related to water have become more and more complex and the analysis requires global and holistic approaches.
The collaboration of the partner universities, based on the use of the internet as a common working platform, aims to establish and share high quality teaching courses, and furthermore to strengthen links between students from the partner institutions in order to build up and spread the know-how of a sustainable water management in Asia. [see for further details]. HydroAsia is a unique opportunity to develop professional skills and knowledge in the field of hydroinformatics and collaborative engineering. The provided study case is a perfect real situation where several approaches can be implanted in order to assess the flood and to elaborate engineering solutions. The international atmosphere provides a unique opportunity to develop teamwork and communication skills and at the same time, to create a first professional network at the international level.
