    <p>I have asked a related question before <a href="https://stackoverflow.com/questions/16342840/why-ocamls-threading-is-considered-as-not-enough">Why OCaml&#39;s threading is considered as `not enough`?</a></p> <p>No matter how "bad" ocaml's threading is, I notice some libraries say they can do real threading.</p> <p>For example, <strong>Lwt</strong></p> <blockquote> <p>Lwt offers a new alternative. It provides very light-weight cooperative threads; ``launching'' a thread is a very fast operation, it does not require a new stack, a new process, or anything else. Moreover context switches are very fast. In fact, it is so easy that we will launch a thread for every system call. And composing cooperative threads will allow us to write highly asynchronous programs.</p> </blockquote> <p>Also <code>Jane Street</code>'s <strong>aync_core</strong> also provides similar things, if I am right.</p> <hr> <p>But I am quite confused. Do <code>Lwt</code> or <code>aync_core</code> provide threading like <code>Java threading</code>?</p> <p>If I use them, can I utilise multiple cpu?</p> <p><strong>In what way, can I get a "real threading" (just like in Java) in OCaml?</strong></p> <hr> <p><strong>Edit</strong></p> <p>I am still confused.</p> <p>Let me add a scenario:</p> <p>I have a server (<code>16 cpu cores</code>) and a server application.</p> <p>What the server application does are:</p> <ul> <li>It listens to requests</li> <li>For each request, it starts a computational task (let's say costs 2 minutes to finish)</li> <li>When each task finishes, the task will either return the result back to the main or just send the result back to client directly</li> </ul> <hr> <p>In Java, it is very easy. I create a thread pool, then for each request, I create a thread in that pool. that thread will run the computational task. This is mature in Java and it can utilize the 16 cpu cores. Am I right?</p> <p><strong>So my question is: can I do the same thing in OCaml?</strong></p>

    1. COI believe it should be possible to use the threading facilities of the JVM with the port of ocaml to that platform, but I did not try it yet.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
