Abstract: A document management system can include an artificial intelligence-based document manager that can perform one or more predictive operations based on characteristics of a user, a document, a user account, or historical document activity. For instance, the document management system can apply a machine-learning model to determine how long an expiring agreement document is likely to take to renegotiate and can prompt a user to begin the renegotiation process in advance. The document management system can detect a change to language in a particular clause type and can prompt a user to update other documents that include the clause type to include the change. The document management system can determine a type of a document being worked on and can identify one or more actions that a corresponding user may want to take using a machine-learning model trained on similar documents and similar users.

Abstract: An instruction is provided for performing a vector string search. The instruction to be processed is obtained, with the instruction being defined to be a string search instruction to locate occurrence of a substring within a string. The instruction is processed, with the processing including searching the string specified in one operand of the instruction using the substring specified in another operand of the instruction. Based on the searching locating a first full match of the substring within the string, a full match condition indication is returned with position of the first full match in the string, and based on the searching locating only a partial match of the substring at a termination of the string, a partial match condition indication is returned, with the position of the partial match in the string.

Abstract: A single architected instruction to produce a signature for a message is obtained. The instruction is executed, and the executing includes determining a sign function of a plurality of sign functions supported by the instruction to be performed. Input for the instruction is obtained, and the input includes a message and a cryptographic key. A signature is produced based on the sign function to be performed and the input. The signature is to be used to verify the message.

Abstract: A method, system, and computer program product are provided for prioritizing transactions. A processor in a computing environment initiates the execution of a transaction. The processor includes a transactional core, and the execution of the transaction is performed by the transactional core. The processor obtains concurrent with the execution of the transaction by the transactional core, an indication of a conflict between the transaction and at least one other transaction being executed by an additional core in the computing environment. The processor determines if the transactional core includes an indicator and based on determining that the transactional core includes an indicator, the processor ignores the conflict and utilizing the transactional core to complete executing the transaction.

Abstract: Performing processing using hardware counters in a computer system includes storing, in association with greatest common divisor (GCD) processing of the system, a first variable in a first redundant binary representation and a second variable in a second redundant binary representation. Each such redundant binary representation includes a respective sum term and a respective carry term, and a numerical value being represented by a redundant binary representation is equal to a sum of the sum and carry terms of the redundant binary representation. The process performs redundant arithmetic operations of the GCD processing on the first variable and second variables using hardware counter(s), of the computer system, that take input values in redundant binary representation form and provide output values in redundant binary representation form. The process uses output of the redundant arithmetic operations of the GCD processing to obtain an output GCD of integer inputs to the GCD processing.

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: In a transactional memory environment including a first processor and one or more additional processors, a computer-implemented method includes identifying a memory location and sending a probe request from the first processor to the additional processors. The probe request includes the memory location. The computer implemented method further includes generating, by each additional processor, an indication including whether the memory location is in use for a transaction by the additional processor. The computer-implemented method further includes sending the indication from each additional processor to the first processor and proceeding, by the first processor, based on the indication.

Abstract: A new zSeries floating-point unit has a fused multiply-add dataflow capable of supporting two architectures and fused MULTIPLY and ADD and Multiply and SUBTRACT in both RRF and RXF formats for the fused functions. Both binary and hexadecimal floating-point instructions are supported for a total of 6 formats. The floating-point unit is capable of performing a multiply-add instruction for hexadecimal or binary every cycle with a latency of 5 cycles. This supports two architectures with two internal formats with their own biases. This has eliminated format conversion cycles and has optimized the width of the dataflow. The unit is optimized for both hexadecimal and binary floating-point architecture supporting a multiply-add/subtract per cycle.

Abstract: A round-for-reround mode (preferably in a BID encoded Decimal format) of a floating point instruction prepares a result for later rounding to a variable number of digits by detecting that the least significant digit may be a 0, and if so changing it to 1 when the trailing digits are not all 0. A subsequent reround instruction is then able to round the result to any number of digits at least 2 fewer than the number of digits of the result. An optional embodiment saves a tag indicating the fact that the low order digit of the result is 0 or 5 if the trailing bits are non-zero in a tag field rather than modify the result. Another optional embodiment also saves a half-way-and-above indicator when the trailing digits represent a decimal with a most significant digit having a value of 5. An optional subsequent reround instruction is able to round the result to any number of digits fewer or equal to the number of digits of the result using the saved tags.
