Zarck posts the same messages on all BOINC projects fora. Not very constructive as he is well aware CUDA and OpenCL are used by projects that have support for GPUs. I don't think he understands the difficulty in writing a BOINC app for the CPU, let alone GPU apps. GPU apps are much more difficult, because of:
1. programming languages (CUDA/OpenCL)are less frequently used than C/C++
2. parallelism of GPUs
3. different GPU architectures and their optimizations
4. missing and/or broken libraries (AMDs FFT library for instance)
5. lack of support by AMD/nVidia

@Ray_GTI-R
My ODROID-U2 is much slower than yours, how did you configure yours?
It is taking 18 hours to finish 4 concurrently!

Mine is running the Android 4.1.1 (1.5 beta from the hardkernel website) with nativeboinc and No-frills CPU Control to prevent it from lowering clocks.

HTC Desire HD (which is quite an old phone, october 2010)
ARM chip: Qualcomm Snapdragon S2 MSM8255 @1.0 GHz
68,749 sec = ~19 hours

Not very fast, but it uses very little power, something like 2-3 Watt.
So 19hours * 0.003KW = 0.057KWh for a WU

Compared to my 2500k @4.0 GHz that takes 1.5 hours, but it can do 4WUs at the same time. I estimate it uses something like 150W.
1.5hours * 0.150KW / 4WUs = 0.056KWh for a WU

In terms of energy efficiency they are roughly comparable. I think new smart-phones with dual or quad cores (@ higher GHz) will probably be even more energy efficient. On the other hand, Ivy Bridge is also ~20% more energy efficient than Sandy Bridge.
