Hi SC good to see you bringing coarz ..... All welcome here.

I am going to be needing to run two instances of WCG on my rigs in a day or two.... Both linux and Windows.... not sure if I remember all the steps to make this happen

PG - trying to behave ... don't hurt yourself :-)

OC - Here is my internal writeup on multi-instancing BOINC in windows ... done as vbscript. Let me know if you need any clarified ... basically steps 1-3 need to happen 1 time for each instance (if you need more than 1 additional instance you'll need to repeat the process for each instance - make sure to use a separate directory and port for each instance. Then step 4 is how you open boinc manager for your "multi-instanced" sessions.

the script in section "Code 3" is all one line, the forum posting forced it to wrap :-(

'---------------------------------------------------------------------
' General Instruction:
' Each instance of BOINC needs its own data directory
' Each instance of BOINC needs its own communication port
'---------------------------------------------------------------------
' Step 1:
' Don't change anything in this section
  Set WshShell = CreateObject("WScript.Shell") 
'---------------------------------------------------------------------
' Step 2:
' Make sure this script file is in boinc's program files directory
' Create a new folder to store your new instance of boinc's data
' Update the line of code in section Code 3 below to the new directory 
'---------------------------------------------------------------------
' Step 3:
' Remove the aspostrophe at the beginning of the section Code 3
' Save and Run this file (double click on it in windows explorer)
' Add an apostrophe at the beginning of section Code 3
'---------------------------------------------------------------------
' Code 3: starts a new instance of boinc
' WshShell.Exec "boinc.exe --allow_multiple_clients --dir C:\BOINC\BOINC_02 --gui_rpc_port 9999 --detach_console --redirectio"
'---------------------------------------------------------------------
' Step 4:
' Put a password in gui_rpc_auth.cfg (used when opening boinc manager)
' If global_prefs_override.xml and/or cc_config.xml exist in your standard
'    boinc data directory copy them into your new boinc's data directory
' Remove the apostrophe at the beginning of the section Code 4
' Save and Run this file (double click on it in windows explorer)
' Add an apostrophe at the beginning of section Code 4
'---------------------------------------------------------------------
' Code 4: 
' Opens boinc manager
' WshShell.Exec "boincmgr.exe /a /n 127.0.0.1 /g 9999 /p nimda0001 /m"
'---------------------------------------------------------------------

I might hit 400K today if things go right..150 threads running

You didn't say how many rigs that takes
