FaH and Boinc

Is it possible to have both running at the same time on a dedicated P4 HT machine?

Possible yes ... logic no.

Both FAH and BOINC probably use the same units to compute their work ... so you'll basically slow them both by sharing a single physical core with HT.

I can live with that.
If I start using Boinc on one machine, who gets credit for any WUs produced?Or is that a no point for team effort?

Keep in mind that the main point of F@H is science, not some credits, thus the faster you return the WU, the better is for science.

With only one actual physical core, we prefer you choose one or the other, but not both.

FAH and BOINC are completely different. FAH credits will go to the username you create when starting FAH, and BOINC credits to the username you created when starting BOINC. The two usernames can be the same, or different.

I'm using 2x Pentium Xeon 2.4 GHz HT Enabled CPUs(HT ON) + Ati Radeon HD4850 AGP.
I'm running 1 GPU + 1 CPU F@H Clients, and two ABC@Home under BOINC Platform.(F@H has a higher priority)
I see no difference in F@H PPD (No more than 5%), because ABC@Home is mainly integer intensive. F@H is mainly floating point intensive, so if you gonna run ABC@Home, that's ok.
I don't know about any other project, that is mainly integer intenvise. If somebody knew, please let us know

ABC conjecture is very important!

I know nothing about ABC#Home, but if it is integer intensive as you say, then you are correct. HyperThreading is especially useful for this sort of combination where one application is mostly integer and the other is mostly Floats (including SSE) and both register as using 100% of half of the CPU. HT is almost useless if you run two heavy integer applications or two heavy float applications simultaneously.

Maybe you can share this info on the ABC@home forum as well.

Could you explain a bit more about this ABC#Home?

That would be a good question to post on the ABC@home forum.

Time to stop this discussion ... it's not a BOINC support forum and the original question that was about has been answered.
