Edit2: Why would the anti-virus software cause trouble for E@H all of a sudden? For what it's worth, I use Norton 360.


When anti-virus (doesn't matter which one) scans in realtime, it'll scan every program that starts up. By doing so, the AV will lock the program --in case it's malignant so it won't be able to spawn its evil doing-- which in the case of a BOINC project's application will mean that it won't be able to communicate with the task that it tries to start. Result: instant fail.

Why all of a sudden? Your AV probably got an update in just prior to when the errors started, which gave it 'reason to believe the Einstein apps were malignant'.

So if the BOINC data

So if the BOINC data directory is exempt from being searched by the anti-virus, but the missing file error continues? Just suffered a bunch of failed tasks.

The good thing is it is happening very quickly, it is also saying it is a file error, that may not be your fault.

I have been processing for a

I have been processing for a month or two and noticed several WU's terminating
with a Computation Error. I also notice when I started my browser while
BOINC was running the browser wouldn't open properly and had to be restarted.
There may be a connection. I am running Firefox with DuckDuckGo.
When I had the last browser failure I went to the BOINC screen and there was
the computation error - it had been running fine up to that point. No idea
why this is happening.

Here is the problem:
Error while computing 614.25 84.76 0.36 --- Binary Radio Pulsar Search (Arecibo) v1.33 (BRP4cuda32nv301)
and
Completed and validated 30,859.22 30,515.96 128.63 251.21 Gravitational Wave S6 LineVeto search (extended) v1.04 (SSE2)

What this is telling me is that the SSE2 units, the ones that run on your cpu are doing fine, BUT the cuda units, the ones running on your gpu, are the ones having problems. There could be several reasons for this..one is that your gpu drivers are not very new, you are using version 311.06 while my Nvidia gpu's are using 314.7, there could be HUGE changes between them. Second it could be your gpu is not powerful enough for you to be crunching at the same time as your pc is doing other things, meaning you need to stop crunching the gpu units while you are using the pc for other things. There are several tweaks you can make that can do this, and they are easy to do. I would upgrade the drivers first though, go here http://www.nvidia.com/page/home.html click on drivers and go thru the menu to find your gpu and then download and install the latest ones. Be sure to stop Boinc before you start the install process, then it is best to restart the pc and let Boinc come back up normally. Then just let it run while you do your thing and see if they finish like they should. If they don't, give it a couple of days, then come back and we can help you tweak Boinc so you can both contribute and use your pc too.
