All matrix files available so far can be downloaded here. The format is as follows: Die neue Version enthält nun auch eine Implementierung von Reactive Streams , mit der Streams in Quasar-Channels transformiert werden können und umgekehrt. Best of Java Such user-defined scoring functions may be used to rank a given set of sequence-structure alignments and benchmark the resulting ranking against a standard-of-truth ranking generated on the basis of one or more structure-based benchmark scores. To do this, just select an optimizer from the drop down list, provide some configuration information and run the optimization. Using NIO with one thread is a bad idea for a few reasons: I've finally chosen my course of action. OS threads can be used in any language but require a lot of RAM and are slow to synchronize and to spawn, while fibers are specific to a certain language or runtime, but are very lightweight, and are synchronized with virtually no overhead.

Unlike links, watches are asymmetric if A watches B, B does not necessarily watch A , and they are also composable: The format is as follows: It allows you to select and configure the scoring formula used to score the alignments. This score conductor allows you to add one or more scoring schemes. Such user-defined scoring functions may be used to rank a given set of sequence-structure alignments and benchmark the resulting ranking against a standard-of-truth ranking generated on the basis of one or more structure-based benchmark scores. Parsing all atoms might be useful for certain energy functions since the distances between the amino acid side chains can be calculated and not only CA distances are available. A common misconception is that NIO allows non-blocking IO therefor its the only model worth benchmarking. Eingeklinkt in den Compiler z. Actors also provide fault detection and identification. The second thing is that you have to specify a score conductor and options that belong to the score conductor scoring schemes used You can reload this file into the GUI and run Quasar using this configuration.

Sign up using Email and Password. Since we do not want to expect that all Quasar users are able to write such an XML configuration file, we developed an intuitive and easy to use graphical user interface to allow users to generate their own configuration files. If this is the case, you have two possiblities: Quasar also offers algorithms for optimizing combinations of scoring schemes with respect to the correlation with the benchmark score.

The Netty WebActor backend will always include the Date header by default but this behaviour can be configured through the co. The session duration for the default implementation is 60 seconds but it can be configured through the co.

Deploying web actors on top of Undertow is as easy as using one of two Undertow handlers: Notice that the session handler is installed as well: The actor context validity is 60 seconds by default but it can be configured through the co.

A web actor is attached to a servlet web session. It can be spawned and attached manually say, after the user logs in and the session is authenticated.

The manual attachment API unfortunately is container dependent. A web actor can also be spawned and attached automatically by letting COMSAT spawn and attach a web actor to every newly created session and this method will be described below.

For automatic deployment, all you have to do is define an actor class one that extends BasicActor or Actor , and annotate it with the WebActor annotation.

If you use embedded container, you have to register WebActorInitializer as a ServletContextListener to your servlet container. Web actors may use websockets.

You can find an example for each of the servers above in the comsat-test-utils project here: A web actor will receive messages of type WebMessage , which is the supertype of all messages that can be received from or sent to a web client.

For messages received from the web client, the sender is a virtual actor representing the web client. Every HTTP request to the resource, associated with the session, will be received by the actor as an HttpRequest message.

All HTTP request messages to a specific web actor instance will come from the same sender. When you respond to an HttpRequest with an HttpResponse , by default, the request stream will close.

An SSE stream is initiated with an HTTP request; then, each event message is written to the response stream and flushed, only the messages need to be encoded according to the SSE standard.

To close the stream, you send a co. WebSocket is a new web protocol for low ish -latency, bi-directional communication between the client and the server.

When the client connects to a web socket, the web actor will receive a WebSocketOpened message, and each following message will be received as a WebDataMessage.

The comsat-kafka module provides a Kafka Producer with an asynchronous send method that will return a Quasar SettableFuture.

The comsat-shiro module adds instrumentation to some Shiro methods via suspendables and suspendable-supers so that developer-provided Shiro Realms can perform fiber-blocking calls when queried by fibers using SecurityUtils:.

When the instrumentation module instruments h , it will find I. Note that this has no effect on other calls to I. The instrumentation module only cares that I.

Quasar supports automatic detection of suspendable methods, without manually marking them at all. Automatic detection of suspendable methods is currently a build-time static analysis tool, which means it must reason conservatively and so it could end up instrumenting more than necessary: Fibers can be serialized while parked, and then deserialized an unparked to continue where they left off.

The unparkSerialized method deserializes the serialized representation of the fiber, and unparks it. You can deserialize the byte array using the serializer returned from the getFiberSerializer method , and pass the uninitialized, unparked deserialized fiber to the unparkDeserialized method.

Methods in the java. Luckily Quasar also provides a lot of troubleshooting tools that can be enabled only when needed and that will tell precisely where and why instrumentation is incomplete: First set the value of the co.

Instrumentation problems usually result from forgetting to mark methods as suspendable, but also look for UnableToInstrumentException stack traces: Another common reason for difficult-to-troubleshoot instrumentation issues is forgetting to mark abstract, interface or overridden methods as suspendable: The verification is telling us that mySuspendable1 is partially instrumented, and specifically the call to myUnmarkedSuspendableMethod2 is not instrumented.

It tells us that mySuspendableMethod3 is not instrumented at all either. Why is that, considering that it calls a method of an anonymous implementation of MyUnmarkedInterface that seems correctly instrumented?

Afterwards a new run will now go through and complete without any errors. Since Quasar fibers are scheduled on threads and have a stack, they can be debugged just like Java threads and this makes things much easier compared to, for example, async APIs.

Sometimes, due to extra calls inserted during instrumentation and not present in the source code, if you step while debugging you could enter Stack methods or other Quasar internal methods: As a last choice, share only the information you can but consider that this could make finding the problem harder: Channels are queues used to pass messages between strands remember, strands are a general name for threads and fibers.

A channel is an interface that extends two other interfaces: Channels are normally created by calling any of the newChannel static methods of the Channels class.

The newChannel methods create a channel with a specified set of properties. Note that not all property combinations are supported.

Messages are sent to a channel using the SendPort. Messages are received from a channel using the ReceivePort. There are versions of receive that block indefinitely or up to a given timeout, and the tryReceive method receives a message if one is available, or returns immediately, without blocking, if not.

A channel can be closed with the close method, found in both ReceivePort and SendPort. All messages sent to the channel after the close method has been called will be silently ignored, but all those sent before will still be available when calling receive.

After all messages sent before the channel closed are consumed, the receive function will return null , and ReceivePort.

As usual, while the blocking channel methods declare to throw SuspendExecution , this exception will never actually be thrown. Quasar provides 4 types of channels for primitive data types: A channel created with the DISPLACE overflow policy is called a ticker channel because it provides guarantees similar to that of a digital stock-ticker: The ticker channel is useful when a program component continually broadcasts some information.

A ticker channel is single-consumer, i. On the other hand, it is possible, and useful, to create several views of the channel, each used by a different consumer strand.

A view which is of type TickerChannelConsumer is created with the Channels. The method returns a ReceivePort that can be used to receive messages from channel.

The fiberTransform method can perform any imperative channel transformation by running transformation code in a new dedicated fiber.

The transformation reads messages from an input channels and writes messages to the output channel. A powerful tool when working with channels is the ability to wait on several channel operations at once.

The Selector class exposes several static methods that allow channel selection. The basic idea is this: Here is an example of using Selector.

For details, please consult the Javadoc:. The example will do exactly one of the following operations: A very concise select syntax for Kotlin is available in the co.

Dataflow, or reactive programming, is a computation described by composing variables whose value may be set and possibly changed at any given time, without concern for when these values are set.

Quasar provides two dataflow primitives: Val and Var in the co. A Val is a dataflow constant. It can have its value set once, and read multiple times.

Vals can also be used as a simple and effective strand coordination mechanism. A Var is a dataflow variable. But this reductionist view of actors does them little justice.

Actors are fundamental building blocks that are combined to build a fault-tolerant application. An actor is a self-contained execution unit with well-defined inputs and outputs.

Actors may write to and read from channels other than their own mailbox. All actors extends the Actor class. MailboxConfig defines the mailbox size the number of messages that can wait in the mailbox channel , with -1 specifying an unbounded mailbox, and an overflow policy.

The overflow policy is currently ignored. An actor is required to implement the doRun method. Actor implements SuspendableCallable so you may run it by setting it as the target of a fiber or a thread via Strand.

An actor can be join ed, just like a fiber. Just like fibers, spawning an actor is a very cheap operation in both computation and memory.

The spawn method returns an instance of ActorRef. All almost interactions with an actor take place through its ActorRef , which can also be obtained by calling ref on the actor.

The ActorRef is used as a level of indirection that provides additional isolation for the actor and actors are all about isolation.

An actor must never pass a direct reference to itself to other actors or to be used on other strands. However, it may share its ActorRef freely.

An actor receives a message by calling the receive method. The method blocks until a message is available in the mailbox, and then returns it.

Because messages can be read by the actor at any time, you must take great care to only send messages that are immutable, or, at the very least, ensure that the sender does not retain a reference to the message after it is sent.

One of the reasons of providing a different receive function for actors is because programming with actors is conceptually different from just using fibers and channels.

I think of channels as hoses pumping data into a function, or as sort of like asynchronous parameters. Actors are a different abstraction.

They are more like objects in object-oriented languages, assigned to a single thread. An actor is a state machine.

It usually encompasses some state and the messages it receives trigger state transitions. This can not only lead to code explosion; it can lead to bugs.

The key to managing a complex state machine is by not handling messages in the order they arrive, but in the order we wish to process them.

This method takes an instance of MessageProcessor , which selects messages out of the mailbox a message is selected iff MessageProcessor.

A simple, fluent API for selecting messages based on simple criteria is provided by the MessageSelector class in the co.

There are several actor systems that do not support selective receive, but Erlang does, and so does Quasar.

The talk Death by Accidental Complexity , by Ulf Wiger, shows how using selective receive avoids implementing a full, complicated and error-prone transition matrix.

To that purpose you can use FiberExecutorScheduler. Note that the actor semantics are preserved: The server behavior is an actor that implements a request-reply model. From this moment on you can use regular jOOQ and everything will happen in fiber-blocking mode rather than ave caesar. Actor state Beste Spielothek in Unterschnaittenbach finden be stored directly in primitive fields of the actor class, or in object fields that may, in turn, contain primitives or ca$hpot casino other kalevala casino. WebSocket is a new web protocol for low ish -latency, bi-directional communication between the client and the server. Comsat runs code in Quasar fibers, which rely on bytecode instrumentation. There are several nice posts and discussions about this topic and the argument amounts to deciding where you want to move the waiting line. Naturally curious and leaning towards exploration, he enjoys gathering knowledge and understanding from people, places and cultures. However, Clojure is all about managing state correctly.
