Hello Gregor,
I regularly use WinBUGS for analysing high-dimensional bioinformatics
data. For many of these applications not only data size could be in
millions but also "parameters"/variables of interests could be in
thousands. Such models compile and run in WinBUGS without much difficulty.
However, irrespective of PC specification WinBUGS is unable to allocate
memory more than (about) 500 MB and the simulation stops. 200-300 MB
memory requirement to load data in bioinformatics is common and with
largish number of samples to be monitored memory requirement easily
exceeds 500 MB. I had reported this problem to the developers of this
software but unfortunately haven't received any solution so far.
Best wishes,
Madhu
