Pei, Thank you. That answers my questions.
I think my real issue lies with my computer only having 4 GB ram with 2.88 GB available when I run cTakes. I am getting a vm creation error C:\apache-ctakes-3.2.1>cd C:\apache-ctakes-3.2.1 C:\apache-ctakes-3.2.1>java -cp "C:\apache-ctakes-3.2.1/desc/;C:\apache-ctakes-3 .2.1/resources/;C:\apache-ctakes-3.2.1/lib/*" -Dlog4j.configuration=file:/C:\apa che-ctakes-3.2.1/config/log4j.xml -Xms512M -Xmx3G org.apache.uima.tools.cvd.CVD Error occurred during initialization of VM Could not reserve enough space for object heap Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit. I am putting in a request from our IT department for more ram and I was debating how much to ask for.

There are models and dictionaries that get loaded into memory- it's defaulted to 3gb to accommodate those. Increasing it may or may not improve performance; in fact it may even decrease it since it may cause more work on the GC. Also, include the version and the pipeline configuration that you are using and the group may have some suggestions. --Pei On Fri, Mar 13, 2015 at 5:01 PM, Fawcett, Mitch <[email protected] > wrote: > Hi, > > I'm brand new to cTakes but I'm really excited about experimenting > with it and developing a Proof of Value demo for my colleagues. > > I have a couple of questions. > > 1) I see that runctakesCVD.bat sets a maximum heap space of 3 gigabytes. > Is that a number that can/should be increased to improve performance? > > 2) Are there discussion threads archived somewhere where I can look > for answers before asking questions? > > Thanks, > > Mitch Fawcett, MBA > Senior Systems Analyst > 13 Read's Way, Suite 202 > New Castle, DE 19720 > Voice 302 327-5192 > [email protected] > > > > > >
