, flash changed to 2 m, Ram changed to 8 m, and other versions were the same as V3.0; (Note that flash and RAM are both small, which is equivalent to configuration downgrade );In v7.0, the CPU and wireless modules are different from those in 6.0. The CPU does not contain the switch chip. In addition, an adm6996 is installed, and the wireless module uses the atheros.

When Matlab is used to generate a large image, an "out of memory" error occurs, causing the image to fail to be generated. Therefore, the virtual memory has to be extended. The specific process records are as follows:

In the MATLAB command line, type the command: feature ('memstats') and get the following results:

Just add the environment variables before the program executes GODEBUG gctrace =1 , such as:GODEBUG gctrace =1 ./xxxx.exeorGODEBUG gctrace =1 go run main.go
The program will display GC information, as follows

When running the LTE simulation platform, I encountered an out of memory problem. I went online for a while and found some solutions. Here I will summarize them.
The generation of out of memory is generally dueProgramDuring the running process, the memory is constantly read and written, resulting in a decrease in the number of consecutive memory segments. Here we will mainly learn some non-Program Improvement Methods and solve this problem by setting the system.

almost completely exposing the highest price they are willing to pay, so a tragic consumer is born in the market.Although bargaining with every consumer is very close to the first-level price discrimination in the dream, this is not done in every industry. In addition to the "clear price" and other policy reasons, there are sometimes more direct reasons. For example, in the telecom industry, telephone charges and traffic fees can only be priced in a unified manner. It is impossible to bargain w

And click "stop". The confirm operation dialog box is displayed;
④ Select "yes" to confirm the operation, and close the dialog box to complete the settings.
3? Optimize Virtual memory
When setting Windows NT virtual memory, you need to properly determine the "start size" and "maximum value" parameters of each drive paging file, which are used to specify the Start space and maximum space of the paging file.
Buffer will not be GC?
To see this problem, I wrote a test code.
var http = require('http') , os = require('os');function create(size, res) { var mb = 1024 * 1024; res.write('free ' + os.freemem() / mb + 'MB\r\n'); res.write('------------- after new ' + size + 'MB buffer\r\n'); var buffer = new Buffer(size
I recently reviewed the database (SQL Server), so I wrote some examples, which are the most basic things... (Don't laugh ...)It is also convenient for beginners to learn sqlserver...

solved. However, SSD disks are best at random reading. This hardware solves this problem naturally.
Therefore, leveldb is out-of-the-box with SSD disk raid.
For the leveldb standard version compilation, see here. Because the standard version uses the C ++ 0x feature, it is not supported on the RHEL platform, so for portability, for Basho, see the Standard C ++ version of port here. For details, see the directory c_src/leveldb.
