I'm reading a book on threads, below is the quote from the book:
When a thread calls the Wait method, the system checks if the Task that the thread is waiting for has started executing. If it has, then the thread calling Wait will block until the Task has completed running. But if the Task has not started executing yet, then the system may (depending on the TaskScheduler) execute the Task by using the thread that called Wait. If this happens, then the thread calling Wait does not block; it executes the Task and returns immediately
Let's say we have the following code:...

if [the unusual happens], there is still a chance (0.01%) that the main thread can execute Sum method, is my understanding correct?
The answer is possibly!
This involves some serious deep-diving into the specific implementation details of how the
TaskScheduler handles tasks that are queued and how the compiler and subsequent smoke and mirrors that run in the back-end of the MSDN language have implemented the state-machines that handle
But in the basic sense you're conclusion, in my opinion, is correct! Per MSDN, if you are using the default
TaskScheduler implements certain optimizations on your behalf such as Task Inlining, like you described, and other optimizations like Work Stealing.
If work stealing and task inlining are not desirable, consider specifying a synchronization context of the tasks that you are creating, to prevent them from performing work on threads other than the ones you specify.
I recently migarted my projekt from dagger 2 to Hilt. Everything went well, but when I modified my WorkManager class, since my worker hasn't done anything.
In logcat I found this error message: WM-WorkerFactory: Could not instantiate hu.crm.crmapp.workmanager.SynchronizationWorker java.lang.NoSuchMethodException: hu.crm.crmapp.workmanager.SynchronizationWorker. [class android.content.Context, class androidx.work.WorkerParameters]
First of all, I checked all of things, that I found in stackoverflow, so I deleted thw workmanager provider from manifest.
The Sync,and PrefManager dependies I also provided, but I don't copy that bunch of code here....

Recently I was reading Google's paper, "MapReduce: Simplified Data Processing on Large Clusters". The words below confuse me. It says
When a map task is executed first by worker A and then later executed by worker B (because A failed), all workers executing reduce tasks are notified of the reexecution. Any reduce task that has not already read the data from worker A will read the data from worker B.
I guess the wokers who executing reduce tasks are just doing what they should do. If they have read data from worker A, they can continue their tasks. Instead, if they haven't, they fail to do the task and report error to master. Then master can re-assign the reduce task to others after worker B finished. So why should they be notified of the reexecution immediately? I think it's unnecessary for some reducers who have read the data they want from worker A....

The thing is reducers do not know that they already read all the data from mapper they want because mapper has failed and did not finish writing data.
Reducers has started reading data early before mapper completed and read some partial data. Mapper could produce more data if not failed.
Mapper has produced partial result files, then failed and new attempt has started.
Typically mappers and reducers are single-threaded and deterministic, this allows restarts and speculative execution. Suppose you do not use some non-deterministic functions like rand(), multi-threading in mapper (custom non-deterministic mapper). Also network/shuffle adds non-determinism. Mapper with multi core/multi threading can produce differently ordered output after restart. Mappers can use output of another mappers and even reducers (for example map-side join in modern implementations). The whole result should be deterministic to make it possible to restart but the order may not, it can be differently grouped files and number of files.
If reducer is commutative and also deterministic (typically yes), you can restart it and get the same result, if it is commutative, no problem with order of rows.
But is it possible to use partial results from one mapper instance (failed) and partial results from another one (new attempt), like read files 0000 - 0004 fron Map1_attempt1 and files 0005 - 0006 from Map1_attempt2 ? Only if mapper produces exactly the same number of files with the same order always. You see, if the whole result of Mapper should be deterministic, partial result may not. It depends on implementation.
I am trying to implement a server and multiple clients. Clients will register with server, and server should give a specific function to the clients to call. I do not want the specific function to be another rpc call. I am trying to make a distributed system for map reduce, where the function will be executed in client processes.
Is there a way to pass a function as response to remote procedure call in Go? Following is what i have tried:
In server :...
ANSWERAnswered 2021-Feb-21 at 10:10
Sending plain functions over the network will not work because of the language design. In a single program you can pass functions as arguments because they are compiled in the same binary. In the server process you can fetch their address/reference since they are mapped in memory but when you send the function you actually send the pointer to it which is not a valid address in the client's memory (hence the invalid pointer error).
To solve your problem I would go for the client registering a set of available functions with a server based on an id (could be a string mentioning the function name). The server will send back the function id in the Run RPC call and the client will select the function based on this id and run it
There are also some experimental libraries that can evaluate Go code at runtime but I would not consider them safe. This is one example.
Is it possible to have some kind of unique symbol value on the type level, that could be used to distinct (tag) some record without the need to supply a unique string value?
In JS there is Symbol often used for such things. But I would like to have it without using Effect, in pure context.
Well, it could even like accessing Full qualified module name (which is quite unique for the task), but I'm not sure if this is a really relevant/possible thing in the Purescript context.
Say There is some module that exposes:...
ANSWERAnswered 2021-Feb-12 at 21:00
Semantics of PureScript as such is pure and pretty much incompatible with this sort of thing. Same expression always produces same result. The results can be represented differently at a lower level, but in the language semantics they're the same.
And this is a feature, not a bug. In my experience, more often than not, a requirement like yours is an indication of a flawed design somewhere upstream.
So the bottom line is: I urge you to reconsider the requirement. Chances are, you don't really need it. And even if you do, manually specified strings might actually be better than automatically generated ones, because they may help you troubleshoot later.
But if you really insist on doing it this way, good news: you can cheat! :-)
You can generate your IDs effectfully and then wrap them in
unsafePerformEffect to make it look pure to the compiler. For example:

It seems because
details is an array you can't just target each item's
"$details.wage" you would probably need to unwind (see the example usage) the array which will produce multiple entries that will have a
details object where you can use

Can someone help explain why?...
ANSWERAnswered 2020-Aug-21 at 11:50
This is only possible if you are using NodePort type service. It's because by design the NodePort is opened on all nodes in the cluster including master nodes.
From the docs
NodePort: Exposes the Service on each Node's IP at a static port (the NodePort). A ClusterIP Service, to which the NodePort Service routes, is automatically created. You'll be able to contact the NodePort Service, from outside the cluster, by requesting
If you are looking for a way to avoid this use ingress with
ClusterIP type service.

You can use woker like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the woker component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
