1) Message boards : ATLAS application : Atlas Native Transient HTTP Errors Uploading Resultfile (Message 47447)

I've used squid v5 from the start.

You can tell boinc to bypass squid for result uploads: boinc manager -> Options -> other options -> http proxy -> don't use proxy for -> http://lhcathome-upload.cern.ch/lhcathome_cgi/file_upload_handler
Or put it in cc_config. Squid is useless for result uploads anyway.

The workaround mentioned in the bug above works also. With client_request_buffer_max_size 512 MB atlas uploads go straight through or usually on their 1st retry.

Why do you need a "boinc account"? Boinc doesn´t deserve to have its own account.

Anyway, look here:

For boinc go to https://boinc.berkeley.edu/download_all.php

cvmfs I've written above.

Singularity should exist in your repositories. singularity-container or something like that is called.

Why would you want to do anything of what is described in the first post? For cvmfs go to https://cvmfs.readthedocs.io/en/stable/cpt-quickstart.html#getting-the-software

For everything else described in the first post there are ready made packages. This shouldn't be a sticky thread.

There is no virtualbox directory in there, create one.

They increased the limit to the level of sixtrack even though sixtrack has a lower average computation time. Seems after cms, I´ll have to abort en masse theory workunits also.

Too many posts, too little substance. Only Harri Liljeroos was on point.



Running 6 or 7 multiple BOINC-clients on 1 machine could be the solution.

No, the solution is, until a patched boinc comes out, the project administrator impose a hard limit for workunits in progress like there is in atlas and (probably) theory. Sixtrack seems to be the same as CMS, but because of sufficiently small computation times they can get away with it.

Until then I use a script that keeps only 50 workunits on board and throws away the rest.
