VTune
VTune Profiler (formerly VTune Amplifier) is a performance analysis tool for x86 based machines running Linux or Microsoft Windows operating systems. Many features work on both Intel and AMD hardware, but advanced hardware-based sampling requires an Intel-manufactured CPU. VTune is available for free as a stand-alone tool or as part of the Intel oneAPI Base Toolkit. Optional paid priority support is available for the oneAPI Base Toolkit. __NOTOC__ Features ; Languages: C, C++, Data Parallel C++ (DPC++), C#, Fortran, Java, Python, Go, OpenCL, assembly and any mix. Other native languages that follow standards can also be profiled. ; Profiles:Profiles include algorithm, microarchitecture, parallelism, I/O, system, thermal throttling and accelerators (GPU and FPGA). ; Local, Remote, Server : VTune supports local and remote performance profiling. It can be run as an application with a graphical interface, as a command line or as a server accessible by multiple users via a web brow ...

List Of Performance Analysis Tools
This is a list of performance analysis tools for use in software development. General purpose, language independent The following tools work based on log files that can be generated from various systems. * time (Unix) - can be used to determine the run time of a program, separately counting user time vs. system time, and CPU time vs. clock time. *timem (Unix) - can be used to determine the wall-clock time, CPU time, and CPU utilization similar to time (Unix) but supports numerous extensions. ** Supports reporting peak resident set size, major and minor page faults, priority and voluntary context switches via getrusage. ** Supports sampling procfs on supporting systems to report metrics such as page-based resident set size, virtual memory size, read-bytes, and write-bytes, etc. ** Supports collecting hardware counters when built with PAPI support. Multiple languages The following tools work for multiple languages or binaries. C and C++ * Arm MAP, a performance profiler ...

OneAPI (compute Acceleration)
oneAPI is an open standard for a unified application programming interface intended to be used across different compute accelerator (coprocessor) architectures, including GPUs, AI accelerators and field-programmable gate arrays. It is intended to eliminate the need for developers to maintain separate code bases, multiple programming languages, and different tools and workflows for each architecture. The oneAPI specification The oneAPI specification extends existing developer programming models to enable multiple hardware architectures through a data-parallel language, a set of library APIs, and a low-level hardware interface to support cross-architecture programming. It builds upon industry standards and provides an open, cross-platform developer stack. Data Parallel C++ DPC++ is an open, cross-architecture language built upon the ISO C++ and Khronos Group SYCL standards. DPC++ is an implementation of SYCL with extensions that are proposed for inclusion in future revisio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Profiler (computer Science)
In software engineering, profiling ("program profiling", "software profiling") is a form of dynamic program analysis that measures, for example, the space (memory) or time complexity of a program, the usage of particular instructions, or the frequency and duration of function calls. Most commonly, profiling information serves to aid program optimization, and more specifically, performance engineering. Profiling is achieved by instrumenting either the program source code or its binary executable form using a tool called a ''profiler'' (or ''code profiler''). Profilers may use a number of different techniques, such as event-based, statistical, instrumented, and simulation methods. Gathering program events Profilers use a wide variety of techniques to collect data, including hardware interrupts, code instrumentation, instruction set simulation, operating system hooks, and performance counters. Use of profilers The output of a profiler may be: * A statistical ''sum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intel Inspector
Intel Inspector (previously known as Intel Thread Checker) is a memory and thread checking and debugging tool to increase the reliability, security, and accuracy of C/C++ and Fortran applications. * Reliability: Find deadlocks and memory errors that cause lockups & crashes * Security: Find memory and threading vulnerabilities used by hackers * Accuracy: Identify memory corruption and race conditions to eliminate erroneous results The nondeterministic nature of threading errors makes it hard to reproduce. Intel Inspector detects and locates threading errors that include race conditions, deadlocks, depth configurable call stack analysis, diagnostic guidance, built-in knowledge of Threading Building Blocks (TBB), OpenMP, and POSIX or Win32 threads. Memory checking includes memory leaks, dangling pointers, uninitialized variables, use of invalid memory references, mismatched memory, allocation and deallocation, stack memory checks, and stack trace with controllable stack trace depth ...
