1) Message boards : Number crunching : Norton Security Stopped GPUGRID Tasks (Message 48350)
Posted 14 hours ago by Toni
The app hasn't changed since last April (acemd is the main application executable, it is definitely necessary).

For some peace of mind, I can suggest to try and submit it to www.virustotal.com .

The "heuristics" seem rather obscure. Even the well-known Atom editor triggered a false positive: https://github.com/atom/atom/issues/13234

Ehm... embarassingly, I wrote CUDA but I meant the NVIDIA Driver.
Luckily, CUDA installers actually also install the graphic driver, so the solution should be ok nevertheless. My bad.

Afaik you just need to install CUDA. There should even be packages ready for Ubuntu. If BOINC was already working, then it should recognize GPUs after installing CUDA.

Not sure if/how it works out of the box when you are not logged in though.

Multiple tasks at once are the way we intend to go for QC (consistent with your preferences of course). The idea is to limit the number of cores to 4, and the BOINC client should manage the available capacity.

The QC multicore app is running well on the majority of hosts.

Here are a couple of tips for the very few cases where it fails. You should look in the "stderr output" of the relevant task.

If you see...

task miniconda-installer reached time limit 360
-- the installer could not be downloaded within 6 minutes. (Firewall? Slow connection?) Resetting the project (when idle) may help.

missing bzip2 executable
or something similar: as the name says. It should be trivial to install bzip2 via your package manager.

wrapper_26198_x86_64-pc-linux-gnu: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by wrapper_26198_x86_64-pc-linux-gnu)
The current app requires a relatively new distribution.

Thanks to both!

Making a windows app will probably need one of the following two solutions. Neither is perfect (by far).

* The "Windows Subsystem for Linux" from Microsoft. It's unfortunately W10 only (as far as I can tell), and probably we'd be the first BOINC project to use it (=headaches).
* A VirtualBox app. Its downsides are known I think.

By the way, question for the gurus: when you run a vbox app, is virtualbox automatically installed on your system?

The 66% is due to our using the boinc wrapper for an app which doesn't report its progress. There are three steps in the WU (install, update, compute) and the third is the long one, hence the 2/3.

If I figure out how, I'll try to limit the number of CPUs requested. I think the client has some control over it as well.

Do not make symlinks. The problem is already solved.

Working/not working pairs are useful for debugging indeed (if they have the same preferences, that is). It was suggested that it was the presence of a GPU, but there are GPU-less counter-examples, like this. The scheduler is a software nightmare...

I'll resume tests later this week. In the meantime, there are 1000 more CPU WUs (QC310big).
