Well late really, last two years after tax department started writing letters.
Serve them right as I got a quite hefty lump sum out of it.
So, after agonising over what to do about GPU based system, I decided I am only dabbling so I opted to simply get an ODROID-XU4 so that I can at least run OpenCL under Python.
Mind you, after toying with Chapel on my quad-core Odriod C1, I will be interested in the Octa-Core Xu4. I did splurge and get an 32GB eMMC 5.0 with Linux.
I went this way as even now the Jetson TK1 is available (as its now obsolete) in Australia, I am rather more interested now in Chapel. Not to mention that Chapel appears to be a better approach than Cuda. That is the appeal, you can take your Chapel code and just change the underlying engine.
So, my cluster will be one ODROID-XU4 and four ODROID-C1. So, 24 cores all up (not taking the general purpose GPU on the XU4 into account).
If I need more grunt a NVDIA card maybe later, in an 8-core PC, maybe.
However, PhD submission draft this weekend so dabbling is all that I will have time for.
