Shared Virtual Memory (SVM) Functions

Description

Shared Virtual Memory (SVM) (Glossary): An address space exposed to both the host and the devices within a context. SVM causes addresses to be meaningful between the host and all of the devices within a context and therefore supports the use of pointer based data structures in OpenCL kernels. It logically extends a portion of the global memory into the host address space therefore giving work-items access to the host address space. There are three types of SVM in OpenCL Coarse-Grained buffer SVM: Sharing occurs at the granularity of regions of OpenCL buffer memory objects. Fine-Grained buffer SVM: Sharing occurs at the granularity of individual loads/stores into bytes within OpenCL buffer memory objects. Fine-Grained system SVM: Sharing occurs at the granularity of individual loads/stores into bytes occurring anywhere within the host memory.

virtual memory exhausted: Cannot allocate memory

问题描述: 购买的Linux服务器,Linux服务器的内存为512MB. 在编译PHP的时候会提示:virtual memory exhausted: Cannot allocate memory,编译失败. 解决方法: 发生该问题的原因是服务器的内存不够,从而导致编译失败. 而购买的Linux服务器,未给你分配虚拟内存,所以可以通过自行增加虚拟内存的方法予以解决 [[email protected] ~]# free -m total used free shared buffers cach
