TWO DC PROJECTS........?????

[klaatu51]

For the past four years I have run SETI and am approaching 2500 WU's but am considering
changing since SETI is ending, and in my case having more and more problems.

Since I have a HT chip I am considering switching to F@H and Climate Prediction, and wanted
to know how bad either, or both, will suffer if I run both.

Before I hit 2500 WU's I will possibly add F@H unless someone tells me that it will
adversely impact F@H. Any thoughts would be appreciated.

I wish I could answer your question completely, but I can give a bump plus say that I run two F@H on a HT chip and with the WUs I have timed I get a 31 percent increase in production by running two instead of just one.

Also I seem to remember that one of the projects runs at a higher priority and so doesn't play nice when trying to run two different projects. I don't think it was F@H because it runs in the lowest (idle) priority.

Somebody will come along with the answers.

And Welcome to the Folding@Home TeAm!

Does mean that there are caching programs for F@H?

No, but we don't often have server problems. Only once in the two months i've been active, and that not for long and only one of many servers. The client can store several finished WUs and send when server is up.

The next batches of WUs are created with data from current ones, so there are deadlines for the WUs such that a slow computer will finish in time, so no caching.

The stats are due soon, (next hour or so) someone will see this then.

You can set F@H to run on (vitrual)CPU0 and the other project to run on CPU1, otherwise known as processor affinity. I'm not 100% sure but you should be able to right click the shortcut (or .exe) for the program and set the affinity there.

I think that Win XP handles the two processes well without needing to set affinity, but I am not sure.

As for ClimatePrediction.NET, it's a PITA to make it run with other DCs simultaneously, cause it's craving everything it can get (at least that's what it used to do about 6 months ago). And there's no HT optimization for CPD.N as well, so I guess that you just have to _try_ running 'em both and see what happens!

Thanks folks. I have installed F@H and it seems to be working, but I have much to learn
about it and how to optimize(sp) it.

My SETI times have gone up considerably for the two WU's that have run since I installed
F@H.

Since I have a dial-up connection I assume I will have to watch the icon to see when to
download another WU.

Thanks again,

EDIT.....My temps have gone up from 44C to 47C. What does "Disable highly
optimized assembly code" mean?

" highly optimized assembly code" is SSE and SSE2. I'd leave it enabled, gives a huge speed boost.
