LHC@home

In the file transfer tab, its sending stops, I give it a try again and it seems to send it, and the speeds are about 80 kbps, it takes forever. So it's better to stop uploading the file. How to fix it?

BOINC pauses uploads automatically if it encounters a problem.
It also automatically resumes uploads after a timeout.

If you cancel the upload the corresponding task will be treated as invalid and you don't get credits.

If you usually don't have upload problems just be patient.
If you always have problems uploading large files you may check your own network for bottlenecks.

Thank you for your answer.
I have no problems with the network.
Sending ready tasks even takes several days to no avail!
I know the rest. Virtual machine disappears - maybe this is a problem?
The only sensible option is to terminate or exclude Atlas on this computer. Because the processor is out of work. It makes me sad because it's the best machine for the LHC.

Yes, this is a very small speed from your ISP.
Uploadspeed 12.83 KB/sek
Downloadspeed 1684.65 KB/sek

Only at the LHC seems to me.

Some questions regarding your network.

Your computer list shows 4 computers.
Are they connected via LAN cable or via wi-fi?

In case of LAN cable
- what bandwidth (e.g. 100 Mbit/s, 1 Gbit/s, ...)
- are they connected through a hub or a switch?

In case of wi-fi
- what max bandwidth
- what measured bandwidth


What bandwidth do you get from your ISP (nominal/measured)?
download:
upload:


LHC tasks temporarily put heavy load on internet routers/firewalls.
Did you check whether the router's CPU/RAM is overloaded?

Virtual machine disappears - maybe this is a problem?

In case of ATLAS that's normal.
At the end of the calculation the VM copies the result back to BOINC and shuts itself down.
BOINC cleans the slot and uploads the result.

Do you have a entry in networking sets in boincmanager?

No.

In my opinion, everything is ok with the computer and the network. Everything is via the cable, I have an Intellinet 522618 switch.
download: 100 Mb / 98 Mb
upload: 30 Mb / 27 Mb
CPU / RAM is not overloaded

Everything is via the cable, ...
download: 100 Mb / 98 Mb
upload: 30 Mb / 27 Mb

ATLAS result uploads should then be done within less than 1 min.
If it's only 1 computer that has the problem and others are fine you may try another LAN cable and another switch port.
If this doesn't help, sorry then I'm out of ideas.

Thank you very much for all your help and advice.

Eureka!
So far, it has helped to change the ETH cable port in the router from LAN2 to LAN1 connecting to the switch.
Upload 330kB. Success, thanks again.
Simple solution, but I wouldn't think of it.[/code]

Hello.
The problem is back. Low upload speed of 45KBps. Only at the LHC.
I have such a problem and only in LHC everything else works well, i.e. up to 100MBps I have the Internet. Computers under 10 x64 win.
I have a router in it, two LAN ports from it, a cable to the switch and it splits everything over the cable.
It used to be helpful to switch the cable to another socket on the router, now nothing helps.
Do you have any ideas?
Network adapter settings in windows?

Have you tried a new cable?
Also, when was the router/modem last rebooted?
