GPGPU and Tomcat

[James Law <JL...@generic-software.com>]

Hi

I've got little knowledge on the way Tomcat works behind the scene so
please excuse my ignorance.

Would Tomcat see any benefits from implementing gpgpu support in the way
that the distributed project "Folding" has seen?

I find GPGPU quite fascinating subject  and for what I can understand
tomcat could potentially see benefits from having massive amounts of
parallel processing power available.

Am I way off the mark or is this worth reading more into?

thanks

To me, the database is one of the more interesting places to use GPUs.  Half a gigabyte of very fast RAM and some high speed simple processors is a good place to put some critical data that you want to search.  Because of the architecture of a typical GPU, it seems unlikely that it's the best place to process complex threaded code, even if (say) the JVM could make use of it.

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

Whether or not any particular application would benefit depends on the characteristics of that application.  Frequently, webapps do relatively minor processing, 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 environments tend to have very minimal GPUs, since they are not used directly by any GUI software.
