The following is screen captures showing utilization
( I also think there is a site parameter set wrong for images in forum , I have cut size to 75% to fit and they are blown up again to wrong page width )
The conversion parameters
after about 90 seconds the timers settle down and become accurate ( one of the few SW's that I have ever experienced)
I decided to close all other programs so that the app has full control this has allowed it to dominate 3 of the8 hyper cores. However the processing time has doubled
At three files cpu utilization drops in half to around 18 - 20 and processing time doubles again, process time settles at around 4 minute
With 4 files the cpu stil utilizes about 1 and a half hyper cores at 20% the conversion of the first file further degrades to about an hour
With the computer loaded with other tasks, the cpu utilization is negligibly affected. The results are similar within a few minutes. Observations show that with normal or highest priority, at most 3 of the 8 hyper threads are utilized. I suspect that the application is not reading the i7 configuration and is processing on 3 of 4 cores rather than 6 or7 of 8. With this in mind I could try to reconfigure the computer not to use hyper threading, this might increase my processing ability to 75%.
Is there any plans to utilize ATI Stream? Many vendors are using CUDA. I found one software that could utilize my ATI stream drivers (11.3), while they detected the 5770 chip set I did not see any improvement in processing over the single file results I had tested against. Those products did allow for multiple file processing across the cores. I am processing 4 -5 5 2 hour blocks of webinars a day. Multi file processing now becomes prohibitive and single file processing is not productive.
Thanks for you help.
