memory-mapped

With the next version of the BCL, . NET developers will be able to use memory-mapped files directly instead of via platform invoke calls.

Memory-mapped files allow applications to work with incredibly large files, even in excess of a gigabyte, in a highly efficient manner.

When working with very large files, native developers turn to a technique known as Memory-Mapped Files.

One of the most common uses of a memory-mapped file is inter-process communication.

As the name implies, a memory-mapped file maps a file-like construct to an address in memory.

When an SPU tries to read from an empty mailbox, it will stop execution until some value is written to its memory-mapped register.

Shared classes are implemented as memory mapped files, so the memory they occupy is shown in the Mapped Data output row.

To help improve startup time, the JVM now works with memory-mapped files.

Some networks do not fully support the memory-mapped files used by the linker.

Despite the name, memory-mapped files are not necessarily real files.

Specifies access capabilities and restrictions for a memory-mapped file or view.

Check that the common language runtime has sufficient permissions to create memory-mapped files.

The Cluster service and Resource Monitor process share a memory-mapped section backed by the paging file.

Memory-mapped files are an operating system feature that links a block of memory to a file.

If we explore the construction of the memory mapped file we can see that there is no stream, we just name the resource.

Containing the number of bytes of physical memory mapped to the process context.

Then, when it is time to start the JVM, instead of loading the system classes from scratch, the memory-mapped files are loaded.

Classes with virtual functions should never be stored in shared data segments nor in memory mapped files.

Instructs the Windows loader to search for the entry point in the specified memory-mapped code.

Performance counters use a memory mapped file, or shared memory, to publish performance data.

Represents the permissions that can be granted for file access and operations on memory-mapped files.

A memory-mapped file is created in a directory called javasharedresources to store the class data.

The memory-mapped registers are used by the PPE to control certain aspects of an SPE, but are not accessible by the SPU code itself.

You can use the stream returned by this method for sequential access to a memory-mapped file, such as for inter-process communications.

Creates a memory-mapped file that has the specified access mode, name, capacity, and access type from a file on disk.

The target file is open or memory-mapped on a computer running Microsoft Windows NT.

Another major performance boost for . NET is support for memory-mapped files.

Committed memory mapped directly into the file system.

Note that these last three points apply to memory-mapped files and shared data segments.

Creates a memory-mapped file that has the specified access mode, name, and capacity from a file on disk.

You can use memory mapped files to allow multiple processes running on the same machine to share data with each other.

I'll discuss an eighth type, MappedByteBuffer, available for memory-mapped files, later in this article.

After reading this article, you should understand NIO, from basic get and put operations to reading a memory-mapped file.

Gets the amount of physical memory mapped to the process context.

If each page-table entry consumes 8 bytes, then that would be 2 MB of overhead for every 1 GB of memory mapped.

In Java 6, the default implementation of the cache has been changed to use a memory mapped file.

The physical memory that is mapped for the guest operating system is actually virtual memory mapped into the process.

An error occurred creating a memory -mapped file.

Win32 creates a shared memory resource by shared memory-mapped files.

This will create the memory mapped file but to start using it we will need a map view.

See the Win32 documentation about memory mapped files.

Even though you have free memory, the systems are paging because the user's applications are using memory mapped files.

If two applications open the same memory-mapped file, changes made by one application will be immediately visible to the other application.
