The 9th Workshop on Python for High-Performance and Scientific Computing (PyHPC) at SC20 will once again bring researchers and developers together to share their experiences of using Python across a wide range of disciplines and applications.

EPCC is a member of the PyHPC Organizing Committee and this year we are co-chairing PyHPC's 9th Workshop on Python for High-Performance and Scientific Computing at SC20 on Friday 13 Nov, 10:00–18:30 EST

Installing Python packages in virtual environments

I recently looked into whether the Python package PyQt5 could be installed on Cirrus, a Tier-2 national service, on behalf of one of our HPC Europa visitors. The Cirrus documentation recommends that you do this using virtual environments and provides a helpful example. However, the problem is that if you subsequently use pip or easy_install to install additional Python packages within the virtual environment you will get a permission denied as it tries to install the package centrally to directories you do not have access rights to. I eventually managed to find a solution.

Summer of HPC: Exploring Edinburgh, Python coding and much more

This guest post is by Dimitra Anevlavi, one of our 2017 Summer of HPC visitors.

Greetings from Edinburgh’s sunny festival season.

During the past few weeks I have been both exploring this vibrant city and cultivating my Python programming skills. I will give you more details about how my work has been going, but first let me introduce you to some of the adventures I’ve had. From Edinburgh Castle to museums of modern art and street performances, this city has it all. The local pubs have their own vivid rhythm, and the traditional delicious fish and chips combination. We were even brave enough to try haggis and deep-fried Mars Bars here. 

Speeding up Python on ARCHER

45 minutes is a long time for a computer: 2,700 long seconds. For a supercomputer like ARCHER that's a lot of time to spend getting ready to do work, but this is the problem faced by the firedrake team who we work with as part of the Marine Technology project.

At EPCC we are currently advertising a number of funded PhD opportunities (see our PhDs in HPC webpage). I am proposing a project entitled Improving the programmability of micro-core architectures, which builds on some of the work I first discussed in a previous blog post on ePython.

Demystifying data input to TensorFlow for deep learning

TensorFlow is an incredibly powerful new framework for deep learning. The “MNIST For ML Beginners” and “Deep MNIST for Experts” TensorFlow tutorials give an excellent introduction to the framework. This article acts as a follow-on tutorial which addresses the following issues:

  1. The above tutorials use the MNIST dataset of hand written numbers, which pre-exists in TensorFlow TFRecord format and is loaded automatically. This can be a bit mysterious if you have no experience of data format manipulation in TensorFlow.
  2. Since the MNIST dataset is fixed, there is little scope for experimentation through adjusting the images and network to get a feel for how to deal with particular aspects of real data.

My work experience at EPCC

Connor Walsh is a school pupil who joined us on a work experience placement last week. Here's his report.

I have been "working" at the EPCC offices at Edinburgh University under Eilidh Troup on a project using Python and Pygame to simulate how much an object would sink in water when you change the mass and the volume of the object.

Edinburgh Software Carpentry workshop attendeesLast week EPCC's ARCHER training team ran another Software Carpentry workshop here in Edinburgh, on 3rd and 4th of December. The workshop provided attendees with an introduction to version control and Git, building programs with Python, automating tasks with Make, and how (and how much) to test programs. These were set within the context of best practices for scientific computing.
