All objects created by the CLR are subject to this hidden memory cost, which can result in an application using many times more memory than expected. For bulk in-memory data storage, swarms of small objects can push the cost up to unacceptable levels, especially on 64 bit systems...
The .NET memory allocation profiling method of Visual Studio Profiling Tools collects information about the size and number of objects that were created in an allocation or destroyed in a garbage collection and additional information about the function call st...

1、deferred allocation(延迟分配), 在第一次使用memory object传输数据时,runtime才对memory object真正分配空间。 这样减少了资源浪费,但第一次使用时要慢一些[一个context多个设备,一个memory object多个location,见前面的blog]。 2.peak interconntect bandwith(峰值内联带宽) host和device之间通过PCIE总线传输数据,...
PDH_MEMORY_ALLOCATION_FAILURE 无法分配内存以支持此函数。 PDH_CSTATUS_NO_MACHINE 指定的计算机处于脱机状态或不可用。 PDH_CSTATUS_NO_OBJECT 无法在指定计算机或指定的日志文件中找到指定的对象。 言论 应调用此函数两次,第一次获取所需的缓冲区大小(将缓冲区设置为 NULL,大小设置为 0),第二次获取数据...
Host memory: 8 GB The program is very simple: First I allocate a large chunk of host memory using malloc (or calloc). I then attempt to allocate several large OpenCL global memory buffers. Usually after two calls to clCreateBuffer, I get an CL_MEM_OBJECT_ALLOCATION_FAILURE. Howeve...
CRITICAL_OBJECT_TERMINATION 错误检查的值为 0x000000F4。 这表示对系统操作至关重要的进程或线程意外退出或已终止。 重要 这篇文章适合程序员阅读。 如果你是在使用计算机时收到蓝屏错误代码的客户,请参阅蓝屏错误疑难解答。 CRITICAL_OBJECT_TERMINATION 参数 ...

Get size of a JavaScript object in Bytes - version 1.x JavaScript does not provide sizeof (like in C), and programmer does not need to care about memory allocation/deallocation. However, according toECMAScript Language Specification, each String value is represented by 16-bit unsigned integer,...
