Hello we have a multi-cpu-server (4 cpu's). On this server runs a boinc-client for linux. At time is only one account to the seti-project attached. Now we want to split the cpu-power and add a second account (differend seti-user). We have no success. Have you a hint for us ? What can we do. Thanks

You can run multiple instances of BOINC client. However, I do not believe it is recommended. Here's how I did it:

1. Create a separate copy of BOINC folder for each client you want to run.

2. Change gui_rpc_auth.cfg file to be different passwords for each instance (so you know which is which later on).

3a. Start ./boinc --daemon --allow_remote_gui_rpc --gui_rpc_port 31416
3b. Start ./boinc --daemon --allow_remote_gui_rpc --gui_rpc_port 31417
...etc...
[Each instance needs its own port, that's probably why it didn't work for you.]

4. You cannot use the manager GUI to control the daemons except the first one (the one on port 31416) as of BOINC version 5.8.16.

5. To send controls to each daemon, use the ./boinc_cmd utility as so:
./boinc_cmd --host localhost:31417 --passwd passphrase --get_state

Remember to substitute the passphrase and --get_state with your gui_rpc_auth password and desired commands respectively. Also, remember that you cannot control which cores run on which CPUs. Setting taskset on boinc won't help control the tasks that it will download and run.

Hy, thanks for this hint - actually a 2nd instance of the client with a different user is running, but in moment only with the option -no_gui_rpc
Next step is activat the rpc_gui.
For other users - I found also a hint for this on:

Thanks more again
