Yes! The UD Agent now runs on all newer versions of Windows.

Also see /faq/3748.

Effective with the June 18, 2002 UD Upgrade, the Agent will no longer work with Windows 95.

Laptop Battery Conservation:
If you install and run the UD Agent on a laptop that is running on DC power (battery) the UD Agent will pause its execution to preserve the life of the battery. The Agent will detect when AC Power is restored, and will re-start. There is currently no way around this.

Update: Apparently the latest version of the Agent will not work on a linux box. One of our member found this thread on the UD forums:

Thanks to Aggie Dan for this info.

UD does not support running the Agent on a Unix-based OS at this time. A version of the Agent for Linux has been developed, but the Think program has not. However, at least one Team Discovery member has successfully run the Agent on Linux (RedHat 7.2) using Wine. See this thread for an explanation.
Thanks to Den for this post.

There is an "Offline Crunching Guide" with instructions on how to use UD on a PC that does not have an Internet connection. Check it out here.
Note: This is a work-around that provides instructions for processing on a non-connected machine, then transferring the files to a computer that has an internet connection.

The answer from UD:

Does the UD Agent take advantage of multi-processor architecture/SMP?

Not at this time. However, we may add this functionality to a future release.

Both UD.exe and the client apps are single thread applications so can only ever run a one CPU core. It can never use multiple cores at the same time (regardless of what windows is telling you).

It is the client apps (ligandfit, Rosetta) that do all the processing (99.9% of it in fact) and will use all available single core CPU time that it can get. It runs at the lowest priority level so it never interferes with any other apps on the system.

The UD.exe app runs at normal priority and only uses up CPU time if you have the apps graphical screen visible, when it is processing the result file for sending to UD or receiving new work. It also uses CPU time when a save occurs.

The P4D processor has Hyper-threading so to Windows it looks like you have 2 processors when in fact you still only have one. HT gives you 2 logical processors, with one having access to the integer unit (for running integer arithmatic) and the other having access to the floating point unit (FPU - to run floating point arithmatic) - remember there is still only one processor with one INT unit and one FPU.

Windows actually lies when using a HT CPU and will never show more than 50% for any application even though ligandfit is actually using 100% of the CPU because it uses the FPU for its calculations. Because HT is a poor mans SMP, Windows cannot accurately show the processor usage hence why you see different results at different times.

If you need to stop the UD Agent for some reason, you should avoid simply stopping it without regard to saving your work. Otherwise, a certain amount of processing, sometimes many hours, can be lost.

Follow the procedure in this FAQ entry for best results.

Also see Snooze mode for a way to temporarily halt the Agent without losing work.

If you need to temporarily shut down your computer, putting the system into hibernate mode will not result in any lost time due to saving issues.

When you install the UD agent you get a registration screen.

Just tick the existing user box and enter your existing username/password.

Then give the new device a unique name.

A recent thread brought up in the forum, addresses some of the issues noted.

Bookmarking this in our FAQ perhaps for the resolution.

Yes, until Vista support is built in to the UD agent you must run it under Administrator Mode and start it manually.

If you reboot your Vista machine you will have to remember to restart UD manually in Administrator Mode.
