Abstract: Methods for simulating an instruction set architecture (ISA) with a instruction set simulator (ISS) are provided. One exemplary embodiment of the methods includes fetching a first decoded instruction during a run time, where the decoded instruction is decoded from an original instruction in a target application program during a compile time preceding the run time. The decoded instruction can designate a template configured to implement the functionality of the original instruction. The method also preferably includes determining whether the fetched instruction is modified from the original instruction and then executing the designated template if the instruction was not modified. The method can also include decoding the original instruction during the compile time by selecting a template corresponding to the original instruction and then customizing the template based on the data in original instruction. The method can also include optimizing the customized template during the compile time.

Abstract: A dataflow instruction set architecture and execution model, referred to as WaveScalar, which is designed for scalable, low-complexity/high-performance processors, while efficiently providing traditional memory semantics through a mechanism called wave-ordered memory. Wave-ordered memory enables “real-world” programs, written in any language, to be run on the WaveScalar architecture, as well as any out-of-order execution unit. Because it is software-controlled, wave-ordered memory can be disabled to obtain greater parallelism. Wavescalar also includes a software-controlled tag management system.

Abstract: Embodiments include a system for loading components with complex intra-dependencies. Components in the system may be assigned at start up to a common loader module. The system detects reference cycles amongst the set of components in the system. All components in a reference cycle may be assigned for loading to the same common loader. This system avoids deadlock scenarios by identifying reference cycles at start up and assigning each cycle to a single common loader. The embodiments of the system also analyze components to be loaded that are identified after start up to determine if they cause a new reference cycle. Components that cause a new reference cycle may not be allowed to be loaded to prevent deadlock loading scenarios.

The plug-in leverages the debugger's user-interface and engine. The plug-in can be a controller that subscribes to common notifications and is guided by a state machine, which stitches together a script control channel with an existing debug channel.

Abstract: Generating mixed-mode operations in the compilation of program code for processors having vector or SIMD processing units is disclosed. In a preferred embodiment of the present invention, program instructions making up the body of a loop are abstracted into virtual vector instructions. These virtual vector instructions are treated, for initial code optimization purposes, as vector instructions (i.e., instructions written for the vector unit). The virtual vector instructions are eventually expanded into native code for the target processor, at which time a determination is made for each virtual vector instruction as to whether to expand the virtual vector instruction into native vector instructions, into native scalar instructions, into calls to pre-defined library functions, or into a combination of these. A cost model is used to determine the optimal choice of expansion based on hardware/software constraints, performance costs/benefits, and other criteria.

Abstract: Embodiments relate to solving conflicts in assembler programs. An aspect includes generating an internal representation of the control flow of the source code of the assembler program, the internal representation including nodes for every instruction and a directed edge for every possible flow of control between nodes. Data attributes are attributed to the nodes and/or the edges to store the information about whether the resource used by an instruction is available or for which amount of time is unavailable. A data-flow analysis is the applied to the internal representation of the control flow of the source code to determine whether the resource used by an instruction of the assembler program is available or for which amount of time is unavailable. Each node is checked for whether the instruction accesses a resource which is unavailable. An appropriate action is then taken to overcome the resource conflict.

The method and system include selecting a memory page of host application code, translating the contents of the selected memory page of host application code, saving the translated contents of the selected memory page into a stub code area, overwriting the selected memory page of host application code; removing host page permission for execution of code in the selected memory page of host application code, and emulating the translated contents of the selected memory page when an exception is raised as a result of attempted access to the selected memory page of host application code.

Abstract: This invention provides a compliance assessment system and tool for efficiently assessing compliance programs and managing compliance program assessments across an organization. Compliance activities are measured against a group of Compliance Program Element Requirements (CPR's) that are used to assess LOB compliance programs. The CPR's define the minimum standards for the LOB's documentation and execution of its compliance program. Assessment results are documented and a compliance program assessment data sheet is developed. A rating is also provided for the status of the documentation supporting the compliance program and the effectiveness of the execution of the compliance program. From these inputs the tool of the invention automatically calculates a score representative of the adequacy and effectiveness of the compliance program. The tool also assigns a color code based at least in part on the score. Reports may be generated that can be used to determine compliance trends.

Abstract: A compiler is configured to determine a set of points in a flow graph for a software program where multithreaded execution synchronization points are inserted to synchronize divergent threads for SIMD processing. MIMD execution of divergent threads is allowed and execution of the divergent threads proceeds until a synchronization point is reached. When all of the threads reach the synchronization point, synchronous execution resumes. The synchronization points are needed to ensure proper execution of the certain instructions that require synchronous execution as defined in some graphics APIs and when synchronous execution improves performance based on a SIMD architecture.

Abstract: A method and system of auto parallelization of zero-trip loops that substitutes a nested basic linear induction variable by exploiting a parallelizing compiler is provided. Provided is a use of a max{0,N} variable for loop iterations in case of no information is known about the value of N, for a typical loop iterating from 1 to N, in which N is the loop invariant. For the nested basic induction variables, an induction variable substitution process is applied to the nested loops starting from the innermost loop to the outermost one. Then a removal of the max operator afterwards through a copy propagation pass of the IBM compiler is provided. In doing so, the loop dependency on the induction variable is eliminated and an opportunity for a parallelizing compiler to parallel the outermost loop is provided.
