Yanrong Kan｜5 Trends of Storage Automation in 2022
Currently, storage automation has been around for decades. In its early days, it was a way to save storage administrators time when moving data, provisioning or decommissioning storage, splitting disks into volumes and LUNs (logical unit numbers), and other manual tasks that used to consume a lot of it. Over time, these capabilities have been […]

"Supercomputer" – GPU cloud server
1. What is GPU cloud server To understand cloud GPU, first, we need to understand what is GPU? GPU is a concept relative to CPU, that is, graphics processor. As graphics processing becomes more and more important in modern computers (especially home systems, game enthusiasts), a dedicated graphics core processor is required. . Simply put, […]

400,000 prize pool + top cloud service resources, the cloud computing competition series of public courses officially launched
The Fortran compiler, introduced 80 years ago, is still widely used today in meteorological modeling, fluid mechanics, computational chemistry, and other disciplines that require complex linear algebra and powerful computing power. It is also because of the invention of the Fortran compiler that Frances (Fran) Allen became the world's first female Turing Award winner. From […]

In the field of high-performance computing, what are the parallel clusters of GPU?
1、 Foreword The high performance of GPU cluster is mainly attributed to its large-scale parallel multi-core structure, high throughput in multi-threaded floating-point arithmetic, and the use of large on-chip cache, which significantly reduces the time of a large amount of data movement. We can say that GPU cluster is more cost-effective than traditional CPU cluster. […]

IGear uses this little magic to increase the training speed of the model by 300%
A high-precision AI model is inseparable from a large number of high-quality data sets, which are often composed of annotation result files and a large number of pictures. In the case of a large amount of data, the training cycle of the model will be correspondingly prolonged. So what’s a good way to speed up […]

Analysis and learning of PHP and swoole
php PHP we use is mainly used for web development. We call PHP FPM to process the business logic of the server through nginx, Apache and other server-side programs. After processing, PHP withdraws memory and returns the results. It can be seen that an HTTP needs to load all PHP files once. This is also […]
