AMD CodeXL: comprehensive developer tool suite for heterogeneous compute

October 9th, 2012

AMD CodeXL is a new unified developer tool suite that enables developers to harness the benefits of CPUs, GPUs and APUs. It includes powerful GPU debugging, comprehensive GPU and CPU profiling, and static OpenCL™ kernel analysis capabilities, enhancing accessibility for software developers to enter the era of heterogeneous computing. AMD CodeXL is available for free, both as a Visual Studio® extension and a standalone user interface application for Windows® and Linux®.

AMD CodeXL increases developer productivity by helping them identify programming errors and performance issues in their application quickly and easily. Now developers can debug, profile and analyze their applications with a full system-wide view on AMD APU, GPU and CPUs.

AMD CodeXL user group (requires registration) allows users to interact with the CodeXL team, provide feedback, get support and participate in the beta surveys.

Panoptes: A Binary Translation Framework for CUDA

May 22nd, 2012

Traditional CPU-based computing environments offer a variety of binary instrumentation frameworks. Instrumentation and analysis tools for GPU environments to date have been more limited. Panoptes is a binary instrumentation framework for CUDA that targets the GPU. By exploiting the GPU to run modified kernels, computationally-intensive programs can be run at the native parallelism of the device during analysis. To demonstrate its instrumentation capabilities, we currently implement a memory addressability and validity checker that targets CUDA programs.

Panoptes traces targeted programs by library interposition at runtime. Read the rest of this entry »

CUDA 4.1 Released

January 26th, 2012

Today NVIDIA released CUDA 4.1, including a new CUDA Toolkit, SDK, Visual Profiler, Parallel Nsight IDE and NVIDIA device driver.

CUDA 4.1 makes it easier to accelerate scientific research with GPUs with key features including

  • a redesigned Visual Profiler with automated performance analysis and expert guidance;
  • a new LLVM-based compiler that generates up to 10% faster code; and
  • 1000+ new imaging and signal processing functions in the NPP library.

The CuSparse library included with CUDA 4.1 has a new tridiagonal solver and 2x faster sparse matrix-vector multiplication using the ELL hybrid format, and the CuRand library included with CUDA 4.1 has two new random number generators. Read the rest of this entry »

GPU-Ocelot 2.0 Released

February 8th, 2011

GPU-Ocelot LogoOcelot 2.0.969 brings CUDA 3.2 and Fermi support to a stable release. Ocelot is a BSD-licensed open source implementation of the CUDA runtime, a PTX emulator, and a mid-level PTX compiler.

Here is a feature list for 2.0.969:

  • PTX 2.2 and Fermi device support: Floating point results should be within the ULP limits in the PTX ISA manual. Over 500 unit tests verify that the behaviour matches NVIDIA devices.
  • Four target device types: A functional PTX emulator. A PTX to LLVM to x86/ARM JIT. A PTX to CAL JIT for AMD devices (beta). A PTX to PTX JIT for NVIDIA devices.
  • A full-featured PTX 2.2 IR: An analysis/optimization pass interface over PTX (Control flow graph, dataflow graph, dominator/postdominator trees, structured control tree). Optimizations can be plugged in as modules.
  • Correctness checking tools: A memory checker (detects unaligned and out of bounds accesses). A race detector. An interactive debugger (allows stepping through PTX instructions).
  • An instruction trace analyzer interface: Allows user-defined modules to receive callbacks when PTX instructions are executed. Can be used to compute metrics over applications or perform correctness checks.
  • A CUDA API frontend: Existing CUDA programs can be directly linked against Ocelot. Device pointers can be shared across host threads. Multiple devices can be controlled from the same host thread (cudaSetDevice can be called multiple times).

Ocelot is available under a BSD license at http://code.google.com/p/gpuocelot.
