CLRium # 6: Pair report on Lock-Free, a lot of theory and practical knowledge

Very soon, November 29-30 in St. Petersburg and December 06-07 - in Moscow we will launch the sixth .NET seminar . This time on the topic of multithreading and competitiveness. We already wrote about this a couple of times on Habré, but today is the Programmer’s Day and there is a great reason to give you all a compliment: a discount on his visit.

I have news for you: we with Andrei Goncharov , my good friend and associate, decided to make lock-free reports for you, speaking together. It seemed to me that this should greatly revive the atmosphere of the performance. Andrei is now digging into this topic so that sometimes he even has to stop it: the reports will be very interesting and useful.

Yuri Vlasov , my second colleague found the Microsoft.VisualStudio.Threading library, which he uses with pleasure in projects. He decided to tell you about its rich capabilities and applicability in various tasks. This report perfectly completes the lock-free theme, covering issues of theory, complexity assessment, analysis of existing algorithms and building your own questions of good implementation in the form of an industrial library.

In honor of the Programmer's Day, we introduced the promotional code: CLRiumDevDay . It is valid for only two days when you can book tickets. Next - you have 5 days to pay for tickets.

First day - discount = 25%, second = 15%

Where will be held

In St. Petersburg, the seminar changed its location and will be held almost in the center of the city: the art space of the weavers. We rent the entire floor of the building so that you can comfortably accommodate, dine without leaving the building and have fun - during breaks. Because this is an art space, there are many interesting things besides the seminar itself.

In Moscow, the seminar will be held in the traditional Salute Hotel. The choice is simple: the place is well-proven.

A few words about the seminar program

First day program

• We will start with the operating system layer. 6 types of processes, threads, mention fibers (and explain why they are not in .NET). Two large reports that will decompose everything that is in the operating system;
• After the operating system, we’ll talk about CLR mechanics. It has many mechanisms on the basis of which many BCL classes work;
• Next, you will go to dinner to lay down the first layer of information ;
• After lunch, we will take up the BCL layer very tightly. Here are the synchronization primitives. And the complexity and importance of the complexity of algorithms and synchronization contexts. In general, two sound reports. Already at this stage you will feel that your investments will pay off at least on the current project, and in the future - on any interview;
• The third topic of the first day is lock-free algorithms. This is an essential part of our multithreading knowledge. Algorithms that work without locks. And in my humble opinion, it is best not to teach them . They need to understand how they work. This is what we will do: first, we will figure out how to put TK on our own to choose an algorithm based on the requirements. Next, we will analyze how the two algorithms work and, finally, we will independently develop another one.

Second day program

When you get enough sleep (this must be done: the brain assimilates all the information received during sleep) and you come to the seminar, its second part will begin:

• Introductory report on asynchronous APM and EAP models in CLR / BCL. Who says they are out of date? Everything new is well forgotten old, which means the old must not be forgotten: the spiral of development will return to it more than once;
• Functional approach to the development of asynchronous code. Functionality - it is not only in F #. We will understand how to write code in such a way so that it can be easily parallelized and so that it entails the least amount of both locks and allocations;
• Again, to reduce the heat in our heads, we will rest at dinner. Let's talk, change the context.
• After lunch, we will go polish our knowledge. These will be: PLINQ, async / await, the mechanisms of their work.

Justify the employer

If you want to save personal funds and contact the employer, but you don’t know how to do this, below I have prepared a short text that can be used by sending a letter to the management. For those who have already seen it, we hid its contents under a spoiler:

We are waiting for you!
