Tomcat is pure Java (except for the APR connector), so any such support wou=
ld have to be in the JVM, not Tomcat itself.

Whether or not any particular application would benefit depends on the char=
acteristics of that application.  Frequently, webapps do relatively minor p=
rocessing, with the brunt of the work being performed in a data base engine=
 (usually running on a separate system).  The exception is handling SOAP or=
 similar protocols that require extensive (and expensive) parsing.

Also, the server boxes Tomcat is typically run on in production environment=
s tend to have very minimal GPUs, since they are not used directly by any G=
UI software.
