[wildlife] windows xp connection issues

I tried a fix on my end for those who have been having trouble connecting to the server with Windows XP. The scheduler in the header for the main page of csgrid had http://csgrid.org listed for the scheduler instead of https://csgrid.org

Let me know if this fixed anything (or broke anything -- hopefully not)!

[wildlife] EXACT v0.25 and v0.26

There was a bug I missed in the EXACT v0.25 client which will cause it to crash from over allocating memory. Please abort any WUs running with this version ASAP so they don't eat up all your machines memory. I really apologize, it ran correctly for my local tests but I had missed a call to convert one of the input filenames to it's proper location in the client.

That being said, v0.26 should be running fine. I made quite a few improvements to the code, so now it should require about 1/4th the memory as the v0.24 client (so the CIFAR work units will now take less memory that the MNIST work units from v0.24 and before). It's also running ~2x faster. That and I upgraded the back propagation algorithm to use batch normalization which also means we'll be getting better results from it. Pretty excited to see how it runs.

[wildlife] "monster" credit reimbursement update

So it looks like there's only about 100 workunits left for this application, so in order to make things fair I'm just going to wait until they all have finished and then apply the bonus credit. This will make things a bit easier on my end. Sorry for the delay!

[wildlife] review image interface should be giving new work

There was an issue with the work generator for the image review interface that should now be resolved. Let me know if there are any issues getting new work jobs!

[wildlife] PLOS One Article

Susan and her students have published an article in PLOS One on the Wildlife Biology end of things. Here's a link if you'd like to read it:

[wildlife] "monster" workunit credit reimbursement

So I've been trying to come up with a method to reimburse users for the "monster" workunits that some of you have been experiencing. Unfortunately, by the time these come in many of them have been removed from the database so there is not much I can do in terms of reimbursing individual users for that work lost.

That being said, what I'm going to do is on this coming monday, May 8th, I'll provide a reimbursement to each user with credit from the "EXACT MNIST Convolutional Neural Network Trainer" application. I'll provide a one time award to everyone for 15% of the credit they've generated by that application. This was the best I could come up with as the users who experienced the most "monster" workunits also would have crunched the most workunits as a whole.

That being said, if you're experiencing some workunits from the "EXACT MNIST Convolutional Neural Network Trainer" application that are seeing pathologically long runtimes (multiple days), please feel free to abort them, or any workunits that won't be completed before Monday, May 8th for that matter. After the 8th I will still leave the validator up and going for this application to collect any stragglers, but this award will be one time only based on credit for that application as it stands on Monday.

Sorry for all the trouble these have caused and I hope this is a reasonable solution!

[wildlife] application updates

Had some bugs to fix in the 0.23 application so I've just released an 0.24 application which should fix them. Sorry about the computation errors!

[wildlife] new app: EXACT MNIST BATCH

Well, that went quicker than I thought. The new application is released with new workunits (and they seem to be crunching without issue on my systems). This new version of the application changes the memory layout a bit which I hope will fix some of the issues we've seen with the "monster" workunits -- my hunch is that the larger workunits cause caching issues on some processors resulting in the 10x slower runtimes.

The new version of the application uses batch stochastic gradient descent, instead of stochastic gradient descent, which should keep memory accesses closer to each other and make caching better. It also has the benefit of requiring less epochs to train, so the new WUs should run a fair bit quicker in that regard as well.

I've updated the calculation for credit on these workunits which I believe should scale better to larger workunits. This means the deadlines should also be calculated more accurately. Let me know how the credit rate is (especially as the WUs get larger) and if the deadlines are okay so I can tweak things if need be.

Hoping this makes things run smoother! Let me know if you run into any issues.

[wildlife] downtime

I had a bit of a database issue starting things up for the new apps. So work generation will not be happening until I get things up and going with the new app. Hopefully sometime today.

Validation/Assimilation should still occur.

[wildlife] "monster" workunit questions

So I had a couple ideas about the monster workunits. For those of you who are having them, are you running other workunits at the same time? Could you let me know the memory usage of those workunits? Does their performance improve if you only run one EXACT workunit at a time?

What I'm thinking may be happening is that the larger workunits require more memory, and if there are enough other workunits (especially other large EXACT workunits) running at the same time things may end up paging to disk because of memory requirements.
