Setting up a virtual machine for data analysis at the LHC
Analysis? I thought you only posted about electronics? The LHC is now producing data as 50ns bunch crossing and is getting ready to bring that down to 25ns! This means physics analyses are picking up and more people are getting into it. I have been involved...

Characterising the TegraK1 Cortex A15
A Benchmark Characterisation of the Cortex-A15-r3p3 I have run HPL and Coremark from the lowest frequency (204 MHz) to the highest (2.3 GHz). At first I thought the performance per Watt would be interesting but as expected the lower the frequency the lower ...

Hands on the New Nvidia TegraK1
Setup to Measure Power Consumption of the TegraK1 I have been benchmarking the Nvidia TegraK1 on our new Jetson development board for the past few days. I am still busy putting together all the results (mostly of the Cortex-A15 r3p3 and not the GPU, just ye...

Optimal Compiler Flags for ARM
ARM GCC FLAGS To get a good approximation for the ideal set of gcc flags to use on ARM, COREMARK was compiled and run several times with different flag combinations. I used 16 different combinations with what I assumed were the most important generic flags ...
