7.6.13 FAHControl connects to the client and gets thrown out

[JTorset]

After upgrading to version 7.6.13 FAHControl connects to the client and gets thrown out immediately and is repeating this endlessly. Telnet shows same behavior, first successfully connect and FAH greeting text appear and then connection is lost.

Strangely enough, the WebControl is working normally and without the 'refreshing no information' bug that previously happened in Opera, Chrome and new Edge. Old Edge did not have this bug.

Trying to downgrade to earlier version but FAHcontrol is also there getting thrown out of the client after connection. So not sure if the installer allows you to install earlier versions than already installed on the machine. Or else it is a config file somewhere that do not change when downgrading and need editing.

I can't make heads or tails of what you are experiencing.

Can you please post the first 200 lines of the log where it shows your configuration?

Here, see below start of the log.

There is no problem folding or connecting the web control to the client. Only FAHcontrol or telnet fails to connect properly to the client.

You need to leave 127.0.0.1 in the allowed ip addresses.

[PantherX]

Please note that the following flag was discontinued several years ago so you can safely remove it from your system:
05:52:14: <client-type v='bigadv'/>

[bruce]

05:52:14: <allow v='192.168.1.21'/>
05:52:14: <command-allow-no-pass v='192.168.1.21'/>

You removed the required permissions for 127.0.0.1 which is the local FAHControl. They should read 127.0.0.1,192.168.1.21 or something like that.

Not your problem, I just noticed it.

05:52:15:WU00:FS02:0xa7:Calling: mdrun -s frame19.tpr -o frame19.trr -x frame19.xtc -cpt 30 -nt 30

You have your system trying to use 31 CPU threads (one is used to feed data to the GPU)

You may wish to consider setting it to 30 or 27 CPUs instead as they have no large prime factors. 27 is safer than 30 as 30 still has a factor of 5.

You have your system trying to use 31 CPU threads (one is used to feed data to the GPU)

You may wish to consider setting it to 30 or 27 CPUs instead as they have no large prime factors. 27 is safer than 30 as 30 still has a factor of 5.

Domain decomposition by a prime number > 3 seems only to be a Linux issue. I am running on Windows. I have 33 threads for the GPU.

Domain decomposition is a potential problem for the CPU analysis done with FAHCore_a7. Your GPU uses FAHCore_2* which handles things very differently.

Please note that this is a GROMACS issue, i.e. it impacts all the OSes that FahCore_a7 runs on. It would be interesting to see your log file to verify if FahCore_a7 is using 33 CPUs or is it rounding it down to a different number.

Domain Decomp happens with windows as well (honestly - I have seen it) … 33 threads for GPU is a little more than it needs (one thread is usually fine) but obviously if you want to keep a fair bit of CPU for other tasks that perfectly OK … If you are looking to maximise your folding you have more choices - in windows 32thread slots work well - and you could have a second slot of maybe 27threads leaving the rest of the threads for other work and servicing GPU.

It will run "warmer" than a single 31thread slot … and there may be AMD gurus on the forums who would advise the best setup for your (rather nice) cpu … as some CPUs work best (more efficiently, cooler, etc. without too much drop in performance) with no threading on the cores as this can allow the cores to boost higher even if there are fewer threads making up much of the performance hit from halving the threads.
