Images in accelerated memory are much faster to draw on the screen. However, accelerated memory is typically limited and it is usually necessary for an application to manage the images residing in this space. This example demonstrates how to determin…
Memory allocation sequence to dialog work processes in SAP What is the memory allocation sequence to dialog work processes in SAP? When does a work process go to PRIV mode? How to avoid or minimize work process going to PRIV mode ? What are the SAP p…
BACKGROUND OF THE INVENTION The present invention relates generally to single-instruction, multiple-data (SIMD) processing and, more specifically, to a technique for saving and restoring thread group operating state. In a conventional SIMD architectu…

先说明下,本人是在windows系统下用的. 简单介绍一下,是nosql数据库,采用key-value存储方式形式.可用于处理高并发日志.维护top表等. 如果把它完全当初数据库使用,当做小型数据库还可以,因为当key达到一定的数量,性能下降比价明细. 读写性能:读110000次/s,写81000次/s 存储方式:采用内存+文件结合的存储方式.这样性能能够保证,而且即使服务器重启,只会丢失少部分数据.   安装:需要下载redis服务端,同时安装RedisWather可将Redis添加到系统服务…

# Redis 配置文件 # 当配置中需要配置内存大小时,可以使用 1k, 5GB, 4M 等类似的格式,其转换方式如下(不区分大小写)## 1k => 1000 bytes# 1kb => 1024 bytes# 1m => 1000000 bytes# 1mb => 1024*1024 bytes# 1g => 1000000000 bytes# 1gb => 1024*1024*1024 bytes## 内存配置大小写是一样的.比如 1gb 1Gb 1GB 1gB…
