Neural networks are becoming widely used in computer interaction, but in real-world scenarios we see errors. We’ve recently completed research into edge distillation to solve this problem.

It looks like DeepMind-level performance is within our grasp! I took a quick look to see how our 90-core cloud run looks under a profiler

This spring my attention was caught by another interesting result: using a new approach they were able to beat Atari Pong in just 2 hours of training time on a single node by parallelizing the work into…

Not everybody has access to an Infiniband-backed supercomputer, but anyone can launch a fleet of EC2 GPU instances for a few dollars per hour. Can we get similar speedups in the cloud? I decided to find…

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…

Arm MAP isn't just a lightweight profiler to help you optimize your code. It also lets you add your own metrics with just a couple of lines of code.

The memory debugger in Arm DDT assists in fixing a number of common memory usage errors with C, C++ and Fortran codes on Linux.

Dangling pointers are pointers whose memory has been freed but which have not been set to null (or 0x0). This allows a particularly tricky class of bug to arise...

I expected a very straightforward tuning process – after all, this code has been a staple of the HPC community for decades – but as it turns out I was in for a surprise!

In Part 1 I ran Discovar, a life sciences genome assembly code, on one of our internal systems and optimized it to run the benchmark code 7% faster. Of course, physical hardware often performs very differently…

We're going to see what Arm MAP 5.0 can do by profiling three versions of a simple PI calculator program with some added I/O for good fun

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.

Arm Forge is a development tool suite for developing, debugging and optimizing CUDA and OpenACC codes - from GeForce to Tesla and the Kepler K80.

Memory leaks are a killer of long running applications - memory usage keeps growing until finally the memory supply is exhausted and it's "game over". If you’re lucky the system recognizes your application…

We humans can survive in almost every environment on our planet and are beginning to step off it. We command fire hotter than the core of a star and freeze atoms at temperatures cooler than the depths…
