Hi, I just wanted to ask if there is a problem with the scheduler. I have been having a heck of a time getting any work at all for my computer. I am running BOINC Version 7.0.58 and have a Core-I7-3630QM CPU with an Nvidia GTX 660M Video Card.

For the last 2 days everytime I check my computer is only processing 3 wu's at the max because there is no work for it to do. I just checked my results page and it said I had 19 wu's that I was working on which is what I show also but 17 of those are CUDA_Fermi wu's that only the GPU can work on.

I know the Astropulse V6 6.01 wu's are saying that the estimated time is like 228 hours and I'm going through them in about 9 or 10 hours. I'm guessing once I get through enough of them that it will correct itself but since it's only giving me 2 at a time to work on with my 8 CPU cores available that it's gonna take awhile (my other 6 cores have just been idle the last couple of days because I have no work for them to do).

I have been running the UPDATE command several times a day to try and get the schedular to give me some work and sometimes it does but only about 4 wu's and their usually CUDA wu's which my GPU is taking about 40 minutes to process.

What are your cache settings?

According to your All tasks for computer 6946525 page you have 43 tasks, 8 of them are for the CPU, at moment your host hasn't completed it's 10 validations for Astropulse v6,
so those will be estimated to take a huge amount of time, once those 10 validations are done the Astropulse estimates will scale to something like actual.

Hmm, not sure what my cache settings are? I'm still a little new to all this but I set my BOINC settings for the maximum 10 days of work and my prefreneces are set to:

I'm not saying I'm getting no work at all but like currently I'm doing pretty good I have 6 of my 8 CPU's doing work 2 Astropulse, 4 Setiathome enhanced 6.03. The problem is the scheduler wont give me any to cache, and not even enough to keep all my cores busy. The Astropulses will take about 10 hours and the 6.03 wu's take about 40 minutes to process and I have none on hand for even my 2 core's that are idle.

This seems to be the issue, with 10+2 days of cache added to the long estimation of the tasks the scheduller will only give you tasks with deadlines longer than 12 days + the currently estimated times... But as the deadlines are ussually around 14 days, the scheduller will not send anything thinking that you wont be able to make it in time.

Try to set this settings to 3 days + 1 day (or less) and you may get better changes to get more work assigned.

Having the cache set to 10 + 2 days is counter productive, Boinc 7 uses those two settings as High and Low Water marks, it'll try and keep 12 days cache, then every two days, once the amount of work drops below 10 days then it'll ask for work again,
The first setting is also used to say how many days offline you're going to be, so Boinc will try and do all the work 10 days before deadline, Probably the scheduler doesn't think you can finish any Shortie work in time, so it refuses to send any,
Best to set your Cache to something more reasonable, Like 4 + 0.01 With that Boinc will cache four point zero one days work, and very time it drops below four days it'll ask for more.
(with the present limits of 100 CPU and 100 GPU tasks you should easily get that with those settings, any higher setting is point less)

OK thanks for the information I will try changing the settings to what you said. I maxed out the setting thinking it would give me my 100 CPU and 100 GPU tasks to work on during the outage but now all I get is dribbles of work.

I dont know if it's another symtom or not but I have a 24/7 Broadband connection through CenturyLink but my downloads are constantly stalling out and then not even retrying until hours later unless I go and manually restart them. Even the small 360KB Cuda files will stall out over and over again. The 8 Meg Astropulse files could take 10 retries or more to get the whole file.

The Current Hurricane link is constantly at well over 100% Utilisation, causing slow downloads and dropped connections,

Wow your a genius! It made a Vast Improvement to my downloads they're going like gangbusters now and I'm averaging 25KBps download speeds between the two downloads.

The only problem I ran into was that when I hit the 'apply' button after selecting the optimize button in the tcpoptimizer program that it asked me if I wanted to reboot and I clicked yes but it only did a soft reboot and then BOINC couldnt connect to the internet at all so I thought something went wrong but finally tried a full reboot and then it just took off!

Thanks so much for your help.
