    Abstract: A data processing system is presented that includes a communication link, a runtime processor coupled to the communication link, and one or more reconfigurable processors. A reconfigurable processor of the one or more reconfigurable processors is adapted for generating an interrupt to the runtime processor in response to a predetermined event and includes arrays of coarse-grained reconfigurable (CGR) units and an interface to the communication link that couples the reconfigurable processor to the runtime processor via the communication link. The runtime processor is adapted for configuring the interface to the communication link to provide access to the arrays of CGR units through the communication link from a physical function driver and from a virtual function driver.

    Abstract: An apparatus includes a processor and a storage storing instructions causing the processor to determine whether an analysis routine is multi-threaded and calls a library function of a non-threadsafe library, and if so, causes the processor to: instantiate an analysis process for executing the analysis routine on multiple threads; instantiate an instance of the library for execution within a isolated library process; instantiate another instance of the library for execution within another isolated library process; retrieve library metadata providing a function prototype of the library function; employ the function prototype to generate an instance of a bridge routine to enable a call from the analysis routine on a first thread to the library function; employ the function prototype to generate another instance of the bridge routine to enable a call from the analysis routine on a second thread to the library function; and begin execution of the analysis routine.

    Abstract: A novel allocate instruction and a novel API call are received onto a compiler. The allocate instruction includes a symbol that identifies a non-memory resource instance. The API call is a call to perform an operation on a non-memory resource instance, where the particular instance is indicated by the symbol in the API call. The compiler replaces the API call with a set of API instructions. A linker then allocates a value to be associated with the symbol, where the allocated value is one of a plurality of values, and where each value corresponds to a respective one of the non-memory resource instances. After allocation, the linker generates an amount of executable code, where the API instructions in the code: 1) are for using the allocated value to generate an address of a register in the appropriate non-memory resource instance, and 2) are for accessing the register.

    Abstract: A method for automated process distribution includes selecting a process definition; identifying a first process portion and at least one second process portion in the process definition; generating a first further process definition for the first process portion; generating a second further process definition for each the second process portion; generating a corresponding service definition for each the second further process definition. In the method, generating the first further process definition includes generating a process definition element configured to invoke at least one service of the service definitions, and generating the second further process definition includes generating a process definition element configured to offer a service of the service definition corresponding to that second further process definition.

    Abstract: A method, system, and computer program product containing instructions for automatically converting an MPI source code program into an MPI thread-based program. In response to inputs in the form of an MPI source code program and a command, a converter declares a global variable of the MPI source code program as a thread private variable to create a first private variable for a first thread and a second private variable for a second thread. A library is identified to support converting processes to threads during execution of the MPI thread-based program, and the identified library is used to build an executable version of the MPI thread-based program. The identified library may include code to identify instantiation of a new process when the MPI thread-based program is executing, and in response, to cause a corresponding thread for the MPI thread-based program to be instantiated.

    Abstract: In general, in one aspect, the disclosure describes a method that includes initializing a queue for a master thread. A cyclic pointer buffer is created based on heap variables in arguments in the master thread. At least one heap variable is passed from the master thread to a slave thread. A pointer for the master thread is exchanged with a pointer for an entry in the buffer. The entry in the buffer is indicated as being available for processing by the slave thread.

    Abstract: Systems and methods are described for resource locking and thread synchronization in a multiprocessor environment. One method includes restricting access to a protected shared resource by use of a lock; issuing the lock to a requesting software to permit access to the protected shared resource; indicating the issuance of the lock to the requesting software by writing a first value to a lock register; freeing the lock, thereby making the lock available for use by another requesting software, after the requesting software completes accessing the protected shared resource; and indicating that the lock is free by writing a second value to the lock register.
