摘要： Thermal-aware source code compilation including: receiving, by a compiler, an identification of a target computing system, the identification of the target computing system specifying temperature sensors that measure temperature of a memory module; compiling the source code into an executable application including inserting in the executable application computer program instructions for thermal-aware execution, the computer program instructions, when executed on the target computing system, carry out the steps of: retrieving temperature measurements of one or more of the target computing system's temperature sensors; determining, in real-time in dependence upon the temperature measurements, whether a memory module is overheated; if a memory module is overheated, entering a thermal-aware execution state including, for each memory allocation in the executable application, allocating memory on a different memory module than the overheated memory module; and upon the temperature sensors indicating the memory module is no longer overheated, exiting the thermal-aware execution state.

摘要： A computing system includes computer memory of a number of different memory types. An application program compiled for execution on the computing system controls access to a field of a record in the computer memory of the computing system by defining a record that includes one or more fields, the one or more fields including a restricted field having a specification of restricted accessibility when the restricted field is allocated in a particular memory type; allocating an instance of the record in memory of the particular memory type; and denying each attempted access of the restricted field while the record is allocated in the particular memory type.

摘要： In an embodiment, in response to reading a declaration of a function that specifies a name of the function and a type of memory on which the function operates, the name of the function, a pointer to the function, and the type are saved to a template. In response to reading a call statement that specifies the name of the function and an identifier of an object, first code is generated. The first code, when executed, reads the pointer to the function from a virtual function table pointed to by the object, finds an entry in the virtual function table that represents the function, and reads the pointer from the entry in the virtual function table. The call statement, when executed, requests a call of the function. Second code is generated that, when executed, calls the function using the pointer read from the virtual function table.

摘要： Methods, apparatuses, and computer program products for real-time temperature sensitive machine level code compilation and execution are provided. Embodiments include compiling and executing, by a just-in-time (JIT) compiler, machine level code; during execution of the machine level code, determining, by the JIT compiler, an execution temperature for the machine level code, including reading temperature measurements from one or more processor temperature sensors; based on the determined execution temperature, identifying, by the JIT compiler, a portion of the machine level code that, when executed, caused temperature measurements of one or more processor temperature sensors to exceed a predetermined threshold temperature; recompiling, by the JIT compiler, the machine level code including modifying the identified portion to generate a new execution temperature that is lower than the previously determined execution temperature; and executing, by the JIT compiler, the recompiled machine level code.

摘要： A computing system includes a number of memory modules and temperature sensors. Each temperature sensor measures a temperature of a memory module. In such a computing system a garbage collector during garbage collection, determines whether a temperature measurement of a temperature sensor indicates that a memory module is overheated and, if a temperature measurement of a temperature sensor indicates a memory module is overheated, the garbage collector reallocates one or more active memory regions on the overheated memory module to a non-overheated memory module. Reallocating the active memory regions includes copying contents of the active memory regions from the overheated memory module to the non-overheated memory module.

摘要： A method, computer-readable storage medium, and computer system are provided. In an embodiment, a detection is made that at least one thread, in a plurality of threads executing in a computer, has hung. A lock order of a plurality of locks used by the plurality of threads is determined. A determination is made that a first thread in the plurality of threads violates the lock order. After the determination that the first thread violates the lock order, the computer is restarted and the first thread that violates the lock order is scheduled on a reduced-speed processor.
