Abstract: Autonomous recovery from a transient hardware failure by executing portions of a stream of program instructions as a transaction. A start of a transaction is created in a stream of program instructions executing on a first processor of a multi-processor computer. A snapshot of a system state information is saved when the transaction begins. When the transaction ends, store data of the transaction is committed. If a transient hardware failure occurs, the transaction is aborted without notifying the computer software application that initiated the stream of program instructions. The transaction is re-executed on a second processor of the multi-processors, based on the saved snapshot of the system state information.

Abstract: A method and associated computer program product are disclosed for generating an object file for subsequent linking by a linker. The method comprises inserting at least one save instruction before a function call instruction and at least one restore instruction after the function call instruction, the at least one save instruction and the least one restore instruction corresponding to one or more call-clobbered registers. The method further comprises generating a first list of registers that are referenced by the function. The function call instruction includes a first annotation referencing the restore instruction, and the restore instruction includes a second annotation referencing the save instruction. The first and second annotations configure the linker to determine whether to eliminate the save instruction and the restore instruction corresponding to at least one of the one or more call-clobbered registers.

Abstract: A transactional memory system determines whether a hardware transaction can be salvaged. A processor of the transactional memory system begins execution of a transaction in a transactional memory environment. Based on detection that an amount of available resource for transactional execution is below a predetermined threshold level, the processor determines whether the transaction can be salvaged. Based on determining that the transaction can not be salvaged, the processor aborts the transaction. Based on determining the transaction can be salvaged, the processor performs a salvage operation, wherein the salvage operation comprises one or more of: determining that the transaction can be brought to a stable state without exceeding the amount of available resource for transactional execution, and bringing the transaction to a stable state; and determining that a resource can be made available, and making the resource available.

Abstract: A method is disclosed for storing vector data into memory with a processor. The method includes obtaining, by the processor, a variable-length vector store instruction. The method also includes determining that the vector store instruction specifies a vector register for a source, a memory address, and a length, where the memory address and the length are each specified in at least a general purpose register. The method also includes determining whether data should be stored into memory at the memory address using big endian byte-ordering or little endian byte-ordering. The method further includes storing data from the vector register into memory, where if the length is less than a length of the vector register, storing only the data from the vector register specified by the length.

Abstract: A method is disclosed for loading a vector with a processor. The method includes obtaining, by the processor, a variable-length vector load instruction. The method also includes determining that the vector load instruction specifies a vector register for a target, a memory address, and a length, wherein the memory address and the length are each specified in at least a general purpose register. The method also includes determining whether data should be loaded into the vector register using big endian byte-ordering or little endian byte-ordering. The method further includes loading data from memory into the vector register, wherein if the length is less than a length of the vector register, setting one or more residue bytes in the vector register to a pad value, wherein the residue bytes are determined based on the determined byte-ordering.

Abstract: A method and associated computer program product are disclosed for generating an executable file from an object file, the object file being associated with an architecture having a predefined calling convention designating one or more call-clobbered registers. The method comprises identifying, from a first annotation included in the object file with a function call instruction, at least one restore instruction that follows the function call instruction, the function call instruction associated with a predefined function of the object file. The at least one restore instruction corresponds to at least one of the one or more call-clobbered registers. The method further comprises determining, based on at least a first list of registers that are referenced by the predefined function, the first list being included in the object file, whether to eliminate the at least one restore instruction.

Abstract: A control system controls tenant services to various tenants by obtaining tenant attributes for each tenant, with respect to a particular workload. A model is generated that models tenant usage performance for a set of best performing tenants. The model is then applied to a remainder of the tenants to obtain a metric indicative of a likely tenant capacity for incremental usage of the workload. The control system controls the services provided to the tenant based upon the likelihood of adoption metric.

Abstract: An optimizing compiler includes a vector optimization mechanism that optimizes vector operations that are reformatting-resistant, such as source instructions that do not have a corresponding reformatting operation, sink instructions that do not have a corresponding reformatting operation, a source instruction that is a scalar value, a sink instruction that may produce a scalar value, and an internal operation that depends on lanes being in a specified order. The ability to optimize vector instructions that are reformatting-resistant reduces the number of operations to improve the run-time performance of the code.

Abstract: A method is a described for constructing a hearing aid shell that comprises a combination of hard and soft materials. In one embodiment, 3D printing is combined with conventional mold/casting methods so that a first shell portion made of a hard material and a mold for a second shell portion are 3D printed. The mold is then filled with a soft material which is allowed to set to form the second shell portion, and the first and second shell portions are adhesively attached.

Abstract: Embodiments relate to using a local entry point with an indirect call function. More specifically, a linker is provided to generate at application modules that at least partially defines an indirect function call configuration. The linker loads a first address of a function by using a first symbolic reference, and determines that the function pointer value of the first symbolic reference is solely used to perform indirect calls in the same application module, e.g. local-use-only. The linker indicates that the first symbolic reference can be resolved using the local entry point associated with the function, and performs that indirect function call exclusively through the first symbolic reference, thereby reducing execution of operations.

Abstract: Embodiments relate to optimizing an indirect call function. A compiler is provided to identify potential target functions and indicate the potential target functions in the program code. Additionally, the compiler determines and indicates in the program code that the function pointer value resulting from a non-call reference of a function symbol is solely used to perform indirect calls in the same module. A linker can read the indication the compiler made in the program code and optimize the indirect call function.

Abstract: A transaction is detected. The transaction has a begin-transaction indication and an end-transaction indication. If it is determined that the begin-transaction indication is not a no-speculation indication, then the transaction is processed.

Abstract: Embodiments relate to using a local entry point with an indirect call function. A compiler is provided to determine and indicate in the program code that the function pointer value resulting from a non-call reference of a function symbol is solely used to perform indirect calls in the same module, e.g. local-use-only. The compiler loads an address of a function through use of a symbolic reference. When the compiler determines that the value employed by the symbolic reference is used exclusively to perform an indirect function call, the compiler proceeds to resolve a local entry point address of the function, thereby reducing a quantity of operations to be executed.

Abstract: A method, system, and computer product for detecting a virtual object include transmitting a probe signal to objects, receiving an echo signal reflected by at least one object of the objects, generating scan data based on the echo signal, capturing one or more images of the objects, generating image data corresponding to the captured images, computing the scan data to identify each of the objects, computing the image data to identify each of the objects, and determining another object of the objects as a virtual object, responsive to determining that the another object is identified by the computation on the image data and is not identified by the computation on the scan data.

Abstract: Embodiments relate to using a local entry point with an indirect call function. More specifically, an indirect call function configuration comprises a first application module having a target function of the indirect function call, a second application module with a symbolic reference to the target function of the indirect function call, and a third application module to originate an indirect function call. A compiler determines and indicates, in the program code, that the function pointer value resulting from a non-call reference of a function symbol is solely used to perform indirect calls in the same module, e.g. local-use-only. A linker or loader can read the indication the compiler made in the program code. The linker or loader use the local entry point associated with the target function if the target function is defined in the same module as the reference and is local-use-only.
