A method and an apparatus that provide secure executable codes generated during run time via a trusted compiler server are described. An application can send a service request to the compiler server to request executable codes. The compiler server can determine whether the service request is permitted to be served based on a security policy imposed and the security settings associated with the service request. Availability of certain compilers can be allowed if the application is authorized according to the service request.

Methods and apparatuses for secure compilation

A method and an apparatus that instructs a compiler server to build or otherwise obtain a compiled code corresponding to a compilation request received from an application are described. The compiler server may be configured to compile source codes for a plurality of independent applications, each running in a separate process, using a plurality of independent compilers, each running in a separate compiler process. A search may be performed in a cache for a compiled code that satisfies a compilation request received from an application. A reply message including the compiled code can be provided for the application, wherein the compiled code is compiled in direct response to the request, or is obtained from the cache if the search identities in the cache the compiled code that satisfies the compilation request.

Methods and apparatuses for a compiler server

Virtualization of graphics resources and thread blocking is disclosed. In one exemplary embodiment, a system and method of a kernel in an operating system including generating a data structure having an identifier of a graphics resource assigned to a physical memory location in video memory, and blocking access to the physical memory location if a data within the physical memory location is in transition between video memory and system memory wherein a client application accesses memory in the system memory directly and accesses memory in the video memory through a virtual memory map.

A method and an apparatus that optimally compile a source code for a data transformation operation in response to a request from a run-time application are described. A current state of the run-time application is included in the request. The application executes a non-optimized library routine for the data transformation operation while a separate worker thread performs optimized code compilation on the source code for the data transformation operation based on the request at the same time. The request includes a current state of the run-time application. The non-optimized library routine has been pre-built during build time.
