Dears,

we would like to test our new CPU multicore application for quantum chemistry tasks ("QC"). Since it’s the first time we have a CPU app out, I’ll test the behavior of GPUGRID with a relatively large batch that you will see soon. Workunits are named "*QC309big*".

Here’s some features of the app, in short (subject to change):

* Platform: Linux only for now, generic x64.
* Threads: as many as Boinc decides. I guess it depends on your machine, your preferences, and other running tasks in ways which are obscure to me…
* Run time: about 1 CPU hour per WU (so, shorter if multithreading)
* Credit: computed with the default algorithm (tasks are short, don’t expect much). Bonus mechanism for fast turnaround is still on.
* Known bugs: restarts and checkpoints. This should be mitigated with the “keep in memory when suspended” option. Sorry about that, it’s outside of our control.
* Network behavior: the first time you get a WU of this kind it downloads a Python interpreter (miniconda) and then some open-source packages, and installs them in the project directory. The installation is reused whenever possible.
* Disk usage: could go around 1 GB, perhaps more when tasks are running. Resetting the project should remove everything.
* Memory usage: should be around 1 GB when running.

Depending on the results of this test, we’ll start thinking about other platforms.

Thanks and nice crunching!

Toni

the client does not receive WUs, although there are almost a thousand of them and the client is suitable for the requirements (Linux x64). earlier this host was able to receive test tasks for QC and python

please write the exact requirements (memory, disk, OS) specified when generating tasks

Can you check what applications are you accepting in your preferences?

By the way requests are currently as follows:

    <rsc_fpops_est>3e12</rsc_fpops_est>
    <rsc_fpops_bound>250e15</rsc_fpops_bound>
    <rsc_disk_bound>4e9</rsc_disk_bound>
    <rsc_memory_bound>1e9</rsc_memory_bound>

All apps selected & "accept work from other"


Preferences:
max memory usage when active: 1900.76MB
max memory usage when idle: 1980.80MB
max disk usage: 6.71GB (4,47 free)

Another boinc mystery...

Jobs only seem to go to a subset of eligible machines. If anybody out there has a clue of the reason, I'll be glad to hear.

All error out with this:

Good luck for debug

Dears, all three errors mention a missing "readlink" executable. It is surprising, because it's a fairly basic command, but please check if you can run "readlink" in a terminal. If not installed, should be in the "coreutils" package.

It is installed

readlink --version
readlink (GNU coreutils) 8.26
Copyright (C) 2016 Free Software Foundation, Inc.
License GPLv3+: GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html>.

Same here. It is installed readlink version 8.26.

I also have problem with getting new WUs on some of my machines. Looks that ones with Nvidia card get work, and ones without it do not get anything.

---

Is there a particular reason this is a CPU application and not a GPU one?

Same here. It is installed readlink version 8.26.

Same here.

NNW until there's a fix.

On Linux CentOS 7.4 is works fine. I suspect that bolinc is not able to find or execute readlink cmd. Please try executing following commands:

which readlink
ls -l `which readlink`
sudo -iu boinc bash -c 'which readlink'
sudo -iu boinc bash -c 'ls -l `which readlink`'
sudo -iu boinc readlink /lib/libz.so.1

On my CentOS they return following results:

# which readlink
/usr/bin/readlink
# ls -l `which readlink`
-rwxr-xr-x. 1 root root 41800 2016-11-05  /usr/bin/readlink
# sudo -iu boinc bash -c 'which readlink'
/bin/readlink
# sudo -iu boinc bash -c 'ls -l `which readlink`'
-rwxr-xr-x. 1 root root 41800 2016-11-05  /bin/readlink
# sudo -iu boinc readlink /lib/libz.so.1
libz.so.1.2.7

---

# which readlink
/bin/readlink


# ls -l `which readlink`
-rwxr-xr-x 1 root root 43192 Oct 4 20:56 /bin/readlink

The following return nothing
# sudo -iu boinc bash -c 'which readlink'
# sudo -iu boinc bash -c 'ls -l `which readlink`'
# sudo -iu boinc readlink /lib/libz.so.1

Commands do not work for me either.

So, I copied readlink program to usr/bin and now it is working in my ubuntu hosts.

Readlink path usually is /usr/bin but it depend on various packaging and configuration provided by the distro

Don't copy the file from /bin to /usr/bin (or whatever)

just create a symlink. If for same reason readlink will be updated , the file you've copied will not updated

$ sudo ln -sf /bin/readlink /usr/bin/readlink

PS : my readlink path is

$ which readlink
/usr/bin/readlink
