The cTAKES Default Processing Pipeline requires about a minimum of 3G of RAM due to the size of the embedded HSQLDBs (that is the default). However, providing a fair bit of overhead is generally a good idea.
As for multi-threading, I have been using the ThreadSafeLvg class. Per the component-use guide: "cTAKES was not originally designed to be thread safe. If you would like to experiment with making it thread safe, see class ThreadSafeLvg in ctakes-lvg." https://cwiki.apache.org/confluence/display/CTAKES/cTAKES+4.0+Component+Use+Guide Mike On Thu, Jan 31, 2019 at 8:44 AM Baas,Leah <leah.b...@sanfordhealth.org> wrote: > Hi everyone, > > > > I’m setting up a new VM to process ~13,500 files using the cTAKES default > clinical pipeline.
