Instructions for coding new clients?

[wheelguy12]

Thought there would be a stickey on this, and scanning the posts didn't see any such animal, so - where can I find instructions that would be useful for creating new client applications? I also looked at the stickey list of current client apps, and none seem to do what I need for my particular situation, so I'm probably going to write a client using C#.

The only things I have been able to gather so far (may be way off base here, but...)
* clients have to use command line arguments to run the cores
* clients have to parse the log files to get current progress of the cores
* clients have to screen scrape the fah web site to get team and user stats

The V6 client is closed source and not being developed. Parsing the log files has been the only way to support V6 but it's strongly discouraged, particularly since the V7 client (which is currently in beta) has an interface for developers which will be supported. Please see the V7 FAHClient Open Beta forum and the Developers Den forum.

Rather than develop a client monitoring program for the older clients, start developing for the new V7 client. And rather than a sticky, there is a whole forum section... Developer's Den

The client can run command line arguments, but are not required to. They can also be set in the configuration file.
Parsing the log file is the current way, but not the future way.
Monitoring programs to do not to screen scrape to get user stats. Stat flat files are published. Read more here: http://folding.stanford.edu/English/Stats

Yep, I looked at both of those forums also - still no info there about monitoring and controlling the cores. Here are the basic steps that I need to control...
1. download work unit(s) for a given core
2. run core on the given work unit
3. upload result(s) for a given work unit/team/member

Are all of these steps controlled from a given core's command line? If not, then how?

The FAHClient manages the downloading of WUs and the initiation of the FahCores. This is closed source and protected by the EULA. You should read it. Only clients downloaded from Stanford are allowed to connect to their servers. You may not write a new CLIENT, but you can replace FAHControl (which is open-source) to manage the client provided by Stanford.

The fah client handles those tasks. Your monitoring tool cannot.

FYI, the work unit determines the core needed, so you cannot download a work unit for a core. It has to be the other way around.

The user name and team number are specified in the client configuration. The fah client reads those settings, and sends it back with the completed work unit.

And WU download and upload uses encrypted communications to assure data security. No 3rd party tool will ever be allowed to handle downloading and uploading work units.

It may help to be more specific about your progamming goals, so we can point you in the right direction.

What I am trying to do is this - download enough work to keep my machine busy while it is disconnected from the Internet. It should do this in an automated manner so that I don't have to manually configure the controller every day (like has to be done in the V7 client UI now).

Can this be done by coding for the V7 client? I noticed that someone else posted exactly this same problem on this forum 2 years ago, so perhaps some way of doing this has been created by now.

[wheelguy12]

Finally found a link to instructions for communicating with the V7 client. It sounds like I should be able to do what I need by writing a bit of code to continually create enough "slots" while on line to keep the machine busy while off-line, and just have this little tender app running all the time while V7 is running. Here is the link in case someone else is looking for it...

Thanks again for all the help - wow, you guys are fast too

Do note that slot loading (did I just coin a new term?) is not advised by PG, because it slows the project down (hence why it is not offered natively). You will need to take into account the deadlines of each work unit and the quick return bonus. You may time out and you will receive fewer points...

wheelguy12 is running a GPU client, which finishes a WU every few hours, so he needs 8 or more to keep the card folding all day, because the PC only has wireless via phone a few hours a day.

The reason there is not a good solution for this, is because there is no good solution. Caching of work units goes against the goals of the project. The faster the completed work units come back, the faster the science gets done. If you hold a work unit for 24 hours, then you are holding the next generation of work unit going out for 24 hours instead of just 3 hours. By folding offline, you are adding 21 hours delay to every work unit you fold.

Work units are serial in nature. They are time slices, and holding on to one slice holds up the rest. Caching is something that is not supported nor recommended. Sorry.

That being said, until the project formally prevents such actions, or adds enough points disincentive to stop doing this, it can still be done.

Personally, I would use X number of v6 GPU command line clients. Then run them as scheduled tasks at staggered intervals. Then shut them all down at a certain time that you plan to connect each day. Then run X more scheduled tasks so start each client for 5-10 minutes, in staggered steps. This allows each client upload any completed work, and download the next. Then back to the 3 hour stagger...

[wheelguy12]

I understand what you mean about the work units being serial in nature. So, in terms of the speed of finishing a single project element, yes - being offline will hold up that project element. Just as a slow machine taking a work unit slows down the other work units behind it. But, for the larger goal of getting more projects done, it is clearly more beneficial to run 24 hours instead of 6. If this is correct, then adding a capability to automatically queue work that can compensate correctly for the speed of the machine, and the patterns of time it is on line would be beneficial to the project as a whole.

I haven't thought of running multiple v6 command line clients. I suppose that as each one finishes, it will patiently wait for connectivity and upload the results followed by a download of the next work unit. No coding needed! That sounds like the solution for me, so I'll give it a try. The last time I fired up 20 slots in the V7 client, my machine had finished them, and was sleeping when I came home. I just need to find some way to prevent thrashing of the clients for attention of the GPU. Suggestions?

[bruce]

The point is that you're not only delaying one WU, you're planning on delaying a whole bunch of them. Not only does that mean the project runs slower, but that means the project must create extra WUs. If there are N people working on a project, and each of them have work to do, that's an ideal situation. Whenever somebody competes a WU, the server creates a new WU and assigns it to them Since N is not a constant, and can only be estimated, FAH must have K extra WUs sitting on the server so that they don't run out of work, but those extra K WUs also delay the project because nobody is working on them so it's slowed down to N/(N+K).

Now assume that somebody queues up a bunch of WUs and the server runs out of work units to assign. ---> Angry people .... and FAH must increase K, slowing down the project even further.

My suggestion is to create longer WUs. I don't know if it's possible, but let's suppose that you had an option to be assigned WUs from a project that ran for 10 or maybe 100 times as long a simulated time as the present WUs . . . and some method to choose those WUs. Wouldn't that be a significant improvement? It wouldn't be a perfect solution, but from the scientific side of things, it would sure beat the solutions that have been discussed here.

I posted the chart below a few weeks ago after looking in some detail at the seemingly unending series of Nvidia GPU work units in P6801. The design of this project was to have a very wide set of "Runs" (over 10,000 seemingly) that each iterate through an arc of Gens or Time Steps.

My analysis below is speculation, but it may support that it might not be that bad for projects designed like this for some donors to queue up their WU results for a day. With thousands of WUs released for each gen, and a four day cycle, there should be enough time. This is enabled by what I might term a "Wide" design - thousands of Run/clone sets processed in each generation - each time step. The data set below also shows that there are occasional "catch-up" events when the system has proceeded to a subsequent time step, or gen, but has a few WUs out of the Wide arc that didn't get in in time, so are sent out (maybe sent out again if for what ever reason a WU missed its deadline) late.

BTW, as of this moment, P6801 us up to Gen 18. Server 171.64.65.64 has a current backlog of 135,738. I myself have finished at least 615 p6801 WUs in the last 2 1/2 months on my MSI GTX560Ti moderately clocked at 950 MHz.

I traced getting first a couple of days of gen 0, and within that gen, cycling through Clone 1-2-3-4. Within gen 0, clone 1, it iterates through each of the runs. I think that as the results from the, say, 4 clones times 10,000 runs in gen 0 are turned in, that the FAH back end software will generate the work units for gen 1, and load them all up to the servers. It seems that it is taking about four days to cycle through all the WUs for a given gen.

Now, this project 6801 design may be unique, but with what seems like a four day time cycle, it may just support the kind of queuing that wheelguy12 is asking about. But, there are no guarantees in this business.

[7im]

For a quant, you forgot to allow for the human element. Your 4 day cycle only works for wheelguy to cache WUs when all the rest of us continue to NOT cache WUs. If you start promoting that idea again, it blows the speed of the project out of the water when more and more people try to cache WUs. Your analysis falls down at that point.

Thanks, 7im.

re: the topic of caching. I'm spinning possibilities from what I see, absent any definitive info from Stanford on how they REALLY design the projects or what their back end reprocessing of finished WUs into the next gen WUs looks like. I try to avoid the Inductive Fallacy, but I also want to see data to support our premises.

I think there are relatively few folders who want to do heavy work when connected to the net only a couple of hours a day. I wholeheartedly agree that if the whole population of Folders were caching their WUs, the results would be highly skewed. A piece of good news in v7 is the overlapped nature where the client immediately starts processing the next WU at the end of the prior without waiting for the upload will satisfy many who have been pushing for caching WUs.

At the end of the day, do some projects have the resiliency to support a few "cachers"? I think the discussion 7im and others in this thread have made was helpful for a person whose special circumstances led to a caching solution for these very rapid GPU work units.

Inductive Fallacy
Premise 1: Having just arrived in Ohio, I saw a white squirrel.
Conclusion: All Ohio Squirrels are white.
(While there are many, many squirrels in Ohio, the white ones are very rare).
