Subject [users@httpd] Need guidance on using custom OpenSSL engine with Apache Server (Worker MPM)
Date Thu, 11 Dec 2014 08:59:48 GMT

Hi,

I have built a custom OpenSSL engine which will offload RSA decryption operation to GPU. 
The engine requires each incoming request to be handled by a thread. 
As request comes, its data will be placed in a buffer and will be offloaded to GPU once the
buffer threshold is exceeded.

To test this engine, I am using Apache server with Worker MPM enabled. 
To generate concurrent client requests, I am utilizing Apache benchmark tool. 

Ideally, when concurrent requests are issued, each requests will be handled by a server thread,
and the buffer will be filled up with data from all the requests.
However, when tested, the buffer only contains data from 1 request.

I would appreciate if anybody can explain why only single thread is utilizing my engine?

Thanks & Regards,
Mohan
