I. Naming Chapter
1.Go functions, variables, constants, custom types, Packages (package) are named according to the following rules:
1) The first character can be any Unicode character or underline
2) The remaining characters can be Unicode characters, underscores, numbers
3) Unlimited character length

, it can be embedded, based on the class set that is currently loaded. If necessary, you can also undo the optimization.Multithreading : Multithreading brings better interactive response and real-time behavior. Multithreaded compilation is simple.Dynamic : Dynamic is important when some code is added to a running program. The current version of Java allows programmers to know the structure and behavior of objects. It is useful for systems that must parse objects at run time (Java GUI Builder, Sm
dividing the target cache size by the number of available logical processors in a physical processor package. Generally, some cache lines need to access data that is not used as the source or target cache part in the cache block, in this way, the block size can be selected from 1/4 to 1/2 of the target cache size (see chapter 1 ).
The software can use the cpuid'
understand bus and cache Interaction
When the dataset contained in the parallel code segment causes the entire working set to exceed the L2 cache and/or the bandwidth consumed exceeds the bus capacity, be careful. On an Intel Core Duo processor, if only one thread is using L2 cache and/or bus, it is expected to obtain the best benefits of cache and bus systems, because the other
a task unit and processes the cache assigned to a thread.
The gap between each task indicates the synchronization load. The decimal number in parentheses represents a cache index. On an Intel Core Duo processor, the producer thread can store data in the L2 cache to allow the consumer thread to continue the job, minimizing the need for bus traffic.
The producer and consumer thread functions are implemented

This paper mainly explores the problem of the heterogeneous computing of the GPU and multi-core CPUs of OpenCL, and briefly expounds what is the OpenCL heterogeneous computing, describes the characteristics of CPU and GPU, and combines them to make the foreground of heterogeneous computing. Then specifically how to build a multi-GPU and multi-
Now that we are in the 21st century, it is hard to imagine that Java-related books are so scarce, but this is just the case with Java. All the Java-related books were basically published by several Sun engineers, such as the "Hooked on Java" written by Arthur Van Hoff et.al and "The Java" written by Patrick Naughton. Handbook ".
Of course, these books fill the gaps in Java, but each book has 3, 400 pages, which assume that readers understand the program, especially object-oriented programming.
A common problem in multi-core development is false sharing (failure sharing). This problem allows us to look at the compilation of multi-core programs from a completely new perspective, which is the hardware perspective.
On Intel Core 2 Duo processor platform, L2 cache is shared by two cores, while L1 data cache is s

/2 degrees, this will enable the server device to work within 5 degrees of collapse, rather than within 20 degrees, which is both economical and secure. In addition, it is rumored that Intel provides Google with a custom chip for high-temperature design, but James Hamilton, a top expert in the cloud computing field, thinks it is unlikely because although the processor is also very afraid of heat, however, it is much stronger than memory and hard disk,

. NET Core 1.0 was intended to be learned when it was released. However, according to Microsoft's previous release rules, version 1.0 can be regarded as a public beta version and Version 2.0 is stable. Now the 2.1 version has been released, and the previous concerns about its "instability
-known fact is that a single undo block can also contain undo records for multiple transactions. A transaction requests the ownership of the undo block exclusively, pins it, and then uses the block until the block is full (at which point the transaction requests a new undo block and updates its transaction table slot to point to the new block) or the transaction commits. If there is still free space in the undo block after the transaction commits, the block is added to the candidate list of the
The so-called 0 pointer is that this pointer points to the virtual address 0x0.

As you might have guessed, in the wrong code, we called func1 the function and dest passed in a 0-pointer address to the parameter 0x0 .Just like this:func1(p,str,len);
