A tiny foray into Apache Spark & Python

I’ve spent an afternoon playing with Apache Spark (1.0.1) to start to form an opinion on where it might be useful. Here’s a couple of notes. We’re discussing this at PyDataLondon tonight. UPDATE I cover PySpark 1.2, ElasticSearch and PyPy in 2015. You can run Spark out of the box on Linux (I’m using 13.10) […]

IPython Memory Usage interactive tool

I’ve written a tool (ipython_memory_usage) to help my colleague and I understand how RAM is allocated for large matrix work, it’ll work for any large memory allocations (numpy or regular Python or whatever) and the allocs/deallocs are reported after every command. Here’s an example – we make a matrix of 10,000,000 elements costing 76MB and […]

Flask + mod_uwsgi + Apache + Continuum’s Anaconda

I’ve spent the morning figuring out how to use Flask through Anaconda with Apache and uWSGI on an Amazon EC2 machine, side-stepping the system’s default Python. I’ll log the main steps in, I found lots of hints on the web but nothing that tied it all together for someone like me who lacks Apache config […]

New High Performance Python chapters online & teaching a 2 day course on HPC

The last month has been crazy busy, not least because I got to run my first High Performance Python 2 day tutorial at a university. I was out in Aalborg University teaching a PhD group, we covered four blocks: Profiling (CPU and RAM) Compilers and JITs Multi-core and distributed Using less RAM, storage systems and […]
