AMD OpenCL-OpenGL interoperability on Ubuntu Linux
As far as I know, the OpenCL-OpenGL interopability on Linux only works with the amdgpu pro driver. In this post I explain how you can get the CL-GL interop to work on ubuntu. Start...

Deep learning inference engines
I have been working a lot lately with different deep learning inference engines, integrating them into the FAST framework. Specifically I have been working with Google’s TensorFlow (with cuDNN acceleration), NVIDIA’s TensorRT and Intel’s...
Norges fylker og kommuner i GeoJSON format
Her finner du Norges fylke og kommunegrenser i GeoJSON format og EPSG:3857 projeksjon. Disse grensene er opprinnelig hentet fra Geonorge, Norges offisielle kart database. Grensekoordinatene fra Geonorge er bare tilgjengelig i UTM 33 projeksjon,...
Fix NVIDIA driver 387 for Linux kernel 4.13+ on Ubuntu
Apparently, the current NVIDIA drivers (387) which comes with CUDA 9.1 doesn’t compile with the new Linux kernels (4.13+) on Ubuntu. The error report from DKMS will say something like: /var/lib/dkms/nvidia-387/387.26/build/nvidia-uvm/uvm8_va_block.c: In function ‘block_cpu_fault_locked’:...
Object tracking with Kinect and FAST
This video shows the work in progress on an algorithm for tracking objects captured by a Kinect camera using the FAST framework. FAST now comes with a Kinect module which uses libfreenect2 to stream...
Visualizing learned features of a caffe neural network
After training a convolutional neural network, one often wants to see what the network has learned. The following python function creates and displays an image with all convolutions of a specific layer as shown...
OpenCL-OpenGL interoperability problems on AMD GPUs and Linux
After experimenting with the OpenCL-OpenGL interoperability on AMD GPUs on Ubuntu Linux I got some cryptic error messages from X (see below). This happens both for the AMD APP samples like SimpleGL and my...
Memory-mapped files using the boost library
The objective of memory mapping files is to increase I/O performance. Memory mapping a file creates a pointer to a segment in virtual memory and the actual loading is performed by the Operating System...
Measuring runtime in milliseconds using the C++ 11 chrono library
I have been playing around with the new C++ 11 standard. It includes a nice new library called chrono which includes some useful clocks and timers. Below is an example of some macros you...
Getting started with Google Test (GTest) on Ubuntu
Google test is a framework for writing C++ unit tests. In this short post, I explain how to set it up in Ubuntu. Start by installing the gtest development package: sudo apt-get install libgtest-devsudo...
