The easiest way would be to set it on the config only run, it should force the client to recognize that there are 8 cores there and use all of them.
As for running the SMP client as a service stanford do not recommend running it as a service especially under XP. If you want to give it a go though the guides are here:
Deino Client:-

MPICH client:-

I've included both guides as i don't know which client you are using.
As for the heat - yeah its a killer at this time of year, when it gets colder though consider it free heat for your house/apartment
Enjoy the day out
