Detailed description of MySQL Benchmark Test and sysbench tool, Benchmark Test sysbenchPreface
As a background developer, it is necessary to benchmark the database to understand the database performance. This article introduces the basic concepts of MySQL benchmark and detailed methods for using sysbench to

In the previous blog (CI framework Source Code Reading Note 4 guide file CodeIgniter. php), we have seen that the core functions of the CI process are completed by different components. These components are similar to a single module. Different modules implement different functions, and each module can call each other t

FIO-New!
FIO is an I/O tool meant to be used both for benchmark and stress/hardware verification. it has support for 13 different types of I/O engines (sync, MMAP, libaio, posixaio, SG V3, splice, null, network, syslet, guasi, solarisaio, and more ), i/O priorities (for newer linux kernels), rate I/O, forked or threaded jobs, and much more. it supports Linux, FreeBSD, NetBSD, OS X, opensolaris, Aix, HP-UX, and windows.

The MySQL Benchmark test Suite Benchmark is used to install the DBI component. Today, we plan to use the MySQL Benchmark Suite to test the insertion performance. The result is incorrect:

Although AMD's day-to-day task is to zen the momentum, but after all Zen the fastest also have to be the end of the year or the beginning of the IPO. In such a gap, the addition of the upgrade is the pain before the dawn. As a representative of AMD High-performance CPU--FX series, although its historical evaluation has long been conclude, but the market always has a place for the FX series. This year, AMD s
Earlier graphics cards were only used for display, and then 2D acceleration components were added to the graphics card, which were used for the operation of the screen, draw points, draw lines, and so on. With the need of game, three-dimensional simulation and scientific computing visualization, the demand for 3D is gradually increasing, the early drawing work is done by the CPU, to achieve realism and real-time effect, can only draw some simple wireframe model, in the 80 's, Stanford University
Original: http://villadora.me/2014/05/23/amd-define-and-how-to-translate-amd-to-commonjs/There has been a lot of controversy between Commonjs and AMD, and both have evolved and converged on the project. Personally, Commonjs is more developer-oriented, and for developers, it requires a clear version and management, less code and more interference, and less configu
The previous blogs have described some of the DRM drivers, graphics card memory management mechanisms, and interrupt mechanisms, and it should be much easier to read the AMD DRM-driven initialization process.Here is an article written by an AMD developer (put it here for the time being, and then add your own view later).Understanding GPUs from the ground upI get asked a lot on learning how to program GPUs.

scratch register will tell you which interrupt was generated by the drawing command.The fence interrupt handler function is radeon_fence_poll_locked. First read the fence number, know that the fence operation caused the interruption, when the resulting interrupt fence number is the last number, you need to assign the last fence number to the current number, while updating the fence timer. If the interrupt is not the last fence number, the timer needs to be judged and then the fence interrupt qu
