Hello,
I would like to ask for reasonability of Primecoin solo mining on setup 16x Intel Xeon E5-2620 @2Ghz (I'm running on Primecoin-HP).
Thank You very much

1. Run the latest HP client on one of the machines, ensure all CPU threads are used.
2. Go to debug console, type: "getmininginfo"
3. Use this magic:
Here's an updated formula for calculating blocks/day:
blocks/day = chains/day * (0.97 * (1 - fracDiff) + 0.03)
Here fracDiff is the fractional part of the difficulty, i.e. fracDiff = diff - floor(diff).
This is simply assuming that it's a 0.03 probability for the (k+1)'th number being prime in a chain. These result in longer chains which are not subject to the fractional difficulty. This number was produced by the function EstimateNormalPrimeProbability() in my latest code. It's a bit smaller than my previous estimate of 0.035 being the probability.

4. Multiply by 16
5. Look up exchange rate of XPM on any of the sites which list it. http://www.cryptocoincharts.info/#jump-xpm-btc
6. Calculate your obtainable $/day
7. Calculate your costs: electricity - you'll need a wattmeter of some kind.
8. You can now answer your question.
