Linaro High Performance Computing Tools QuickSpecs
Table of Contents
A market-leading tools for debugging, profiling, and optimization of software on any HPC platform, including x86-based platforms and Arm-based platforms as well as GPUs.
Linaro Forge Ultimate brings everything software engineers need to build reliable and optimized code that creates the right results on multiple high-performance computing (HPC) architectures. The suite allows users to debug, profile, and tune for optimal performance—on everything from single threads to complex parallel HPC and scientific codes with MPI (message passing interface), OpenMP threads, NVIDIA CUDA or AMD ROCm. Linaro Forge Ultimate supports debugging and profiling for codes using the latest C, C++ and Fortran compilers on x86-64 (Intel and AMD) and 64-bit Arm hardware.
Overview
Linaro Forge Ultimate brings together Linaro DDT, Linaro MAP and Linaro Performance Reports into a single intuitive interface to provide the ideal package for software development and optimization:
- – Linaro DDT is the No. 1 debugger in research, industry and academia for software engineers and scientists developing C++, C, or Fortran parallel and threaded applications on CPUs, GPUs, Intel, and Arm. Linaro DDT is a powerful tool for automatic detection of memory bugs. Different detection and insightful data view offer easy ways to understand and fix problems.
- – Linaro MAP is a profiler helping to find bottlenecks in computation, communication, synchronization or I/O. Its high-speed, accurate low-overhead measurement and visual scalability tackle even the most challenging performance issues. Whether at one process or at scale, Linaro MAP is designed to work out-of-the-box with no need for instrumentation and no danger of creating large, unmanageable data files. Software engineers developing parallel and threaded applications on CPUs and GPUs rely on Linaro MAP’s insight into optimization.
- – Linaro Performance Reports is the first port of call for understanding application performance. See the type of activity in which your program is spending its time and infer how well it is mapping to your hardware and job configuration. Switch to more detailed tools (such as Linaro MAP) if and when needed.
Standard Features
Linaro DDT
Linaro DDT is a powerful graphical debugger suitable for many different development environments. Linaro DDT includes:
- – Single process and multi-threaded software
- – OpenMP
- – Parallel (MPI) software
- – Heterogeneous software, such as that written to use GPUs
- – Hybrid codes mixing paradigms such as MPI with OpenMP, or MPI with CUDA
- – Multi-process software of any form, including client-server applications
Linaro DDT helps you find and fix problems on a single thread or across hundreds of thousands of threads. It includes static analysis to highlight potential code problems, integrated memory debugging to identify reads and writes that are outside of array bounds, and integration with MPI message queues.
Linaro DDT supports all of the compiled languages that are found in mainstream and high-performance computing, including:
- – C, C++, and all derivatives of Fortran, including Fortran 90
- – Limited Python support (CPython 3.6 - 3.11)
- – Parallel languages/models including MPI, UPC and Fortran 2008 co-arrays
- – GPU languages such as HMPP, OpenMP Accelerators, CUDA and CUDA Fortran and HIP
While many users choose Linaro DDT for desktop development or for debugging on small departmental parallel machines, it is also scalable and fast to beyond petascale, and is depended upon to debug hundreds of thousands of processes simultaneously.
Linaro MAP
Linaro MAP is a parallel profiler that shows you the longest running lines of code and explains why. Linaro MAP does not require any complicated configuration, and you do not need to have experience with profiling tools to use it.
- – MPI, OpenMP, and single-threaded programs.
- – Small data files. All data is aggregated on the cluster and only a few megabytes written to disk, regardless of the size or duration of the run.
- – Sophisticated source code view, enabling you to analyze performance across individual functions.
- – Both interactive and batch modes for gathering profile data.
- – A rich set of metrics that show memory usage, floating-point calculations, and MPI usage across processes, including:
- Percentage of vectorized instructions, including AVX extensions, used in each part of the code.
- Time spent in memory operations, and how it varies over time and processes, to verify if there are any cache bottlenecks.
- A visual overview across aggregated processes and cores that highlights any regions of imbalance in the code.
Performance Reports
Linaro Performance Reports are a non-intrusive performance tool for HPC and scientific software. They analyze the applications running on the system to seek inefficiencies and pinpoint exactly where to focus the optimization work.
A report measures overall information about the computation, communication and I/O providing detail for each of these areas,
including:
- – The time spent in various categories of instruction: memory access, numeric operations, floating point operations
- – I/O – time and the effective performance (transfer rate) of read and write operations to storage
- – Memory – the mean and peak usage of memory per node
- – Communication – MPI time and performance for collective and point-to-point operations
- – Threads – the time spent in computation and synchronization, the physical core utilization and system load
- – GPUs – the utilization and memory use of GPUs
- – Energy – the energy pack add-on reports energy usage and peak power – for system, CPU and GPUs

Technical Specifications
Linaro Forge Ultimate
Installation
Linaro DDT, an industry-leading parallel debugger, and Linaro MAP, a low-overhead line-level profiler for MPI and OpenMP are now part of one common environment: Linaro Forge.
One installation provides everything needed to debug, fix, and profile programs at any scale, limited only by the license. This simplifies installation and maintenance overhead, as well as provides one common, familiar interface for all development tools, making it easy to move between them while working on a piece of code. Users may start Linaro Forge with DDT or MAP and can easily switch to the other tool with a single click while working.
Remote Clients
Linaro Forge has native remote clients for Windows, macOS, and Linux that can connect via SSH to any server or cluster using an existing login process. Users can then run, debug, profile, edit, and compile files directly on the remote machine. The native remote client experience is superior to X forwarding or VNC-based solutions.
