Development Logs

Community Bonding Period

• During the community bonding period, I downloaded BRL-CAD and configured and compiled my build. Initially it had some problems (probably due to my proxy settings), but finally it worked while using Ubuntu 17.04, revision r70379 (last known working version of BRL-CAD with openCL) and AMD APP SDK 2.9.1 as an OpenCL ICD.

• I started to write some code in order to get an advance on my project. This consisted of developing HYP and ARBN shot routines in OpenCL as per my project plan.
