REALTA Pulsar Docker Containers

Docker containers used on the I-LOFAR REALTA nodes for processing pulsar observations.

CUDA Container Requirements

Docker 19.03+
nvidia-docker container toolkit
GPU with SM70+ available (Volta+, lower CCs may be possible by modifying the Dockerfile as needed, but I believe sm_30 is the minimum requirement)

Known issues/TODOs:

Cleanup ENV variables
Pass on packages to see if any can be removed after some changes to image requirements
Not all installed packages have been stress tested as of yet
Intel MKL/IPP libraries fail to be detected at compile time, removed for the time being and isolated to the "Dockerfile_MKLWIP" file. Could allow for a significant speed up, and for increase python performance (intelpython).
mark5access, PsrXML and a few other packages were intended to be installed but appear to have issues compiling, leaving out for now.
PSRCHIVE seems to have some GPU support but it depends on CULA, which at the time of writing seems to be unobtainable as it's behind a registration/licencse wall which is broken.
