Re^2: Regarding firefly working on i3 processor

Hello Sir. A very big thanks to you for your kind help. I had read your weblink on SMP, but was confused, but now your suggestion worked like a charm. I ran 3 instances of FIREFLY (3 different programs) and my CPU was 75% used...Thats really encouraging.
Now can you tell me how should I make use of 100% CPU for just ONE instance of FIREFLY or for a single program 100% CPU usage?

>>Sir i am a physicist curious to dive into computational field. I hve some experience with gaussian...but have left it after trying firefly.. i hve installed 7.1g version on winXP with dual core 2ghz. It used 70% cpu for benzene optimization. I then installed firefly version8 on i3 2330m processor, with avx enabled...i run the same calculations and i get this message "operating system doesnt support avx. So disabling it." And out of 4 cores, only one is used with 25%cpu usage. I want to use atleast 3 cores sir...please help...
