Arm Forge is a development tool suite for developing, debugging and optimizing CUDA and OpenACC codes - from GeForce to Tesla and the Kepler K80. Forge includes the parallel and multi-process CUDA debugger, Arm…
With the continued emergence of innovative, infrastructure-ready Arm-based server platforms, Arm is announcing availability of the Arm Allinea Studio. By providing access to Arm-specific compilers and libraries alongside market-leading debug and optimization…
It’s with great excitement that we’re announcing that Allinea is now a part of Arm.
For over 10 years at Allinea we’ve been on an incredible journey to be your cross-platform tools provider for high performance computing (HPC).
It’s…
In the previous post we parallelized Andrej Karpathy's policy gradient code to see whether a very simple implementation coupled with supercomputer speeds could learn to play Atari Pong faster than the state-of-the-art (DeepMind's A3C at time of…
In episode one we optimized Torch A3C performance on the new Intel Xeon Phi (Knight's Landing) CPU. Arm MAP and Performance Reports identified bottlenecks in our framework and sped up model training by 7x.
To get further gains we found areas of the…
In February, a new paper from Google's DeepMind team appeared on arxiv. This one was interesting – they showed dramatically improved performance and training time of their Atari-playing Deep Q-Learning network. The training speedup was so great that…
This year we're proud to be sponsoring the Student Cluster Competition at SC15. One of the key codes teams will have to optimize for their systems is the classic Linpack benchmark. I decided to have a go on one of our test systems to see what the students…
Recently we've been running bowtie2 on a 16 CPU server with 32 GB RAM. I've tried using the “-p” flag to use more cores but it doesn't seem to make a lot of difference after 8 or so.…
OpenFOAM, developed by ESI-OpenCFD is one of the most popular tools for developing CFD (Computational Fluid Dynamics) applications, along with ANSYS Fluent or CD-Adapco Star-CCM+.
Most modules of OpenFOAM are heavily optimized and offer little room for…
