BOINC Installation for Newbie
Install BOINC by downloading the file from http://boinc.berkeley.edu/download.php. Most users will be fine without the VirtualBox and this can be installed seperately at a later stage (preferred). VirtualBox is handy when it comes to bunkering. For [H] guide on BOINC installation, see old post https://hardforum.com/threads/boinc-installation-walk-through.1768558/.

Bunkering
Bunker period starts from Apr 30, 00:00 UTC and ends on May 5, 00:00 UTC.
During this period, you would like to run as many tasks as possible without uploading the results to the server until the event officially starts.
  1. Bunker technique #1. If you have low core count CPU. Create and add this cc_config.xml file to your directory C:\ProgramData\BOINC before running your BOINC manager. A delay of 30 seconds it to prevent any unstable performance. You can change this to suit your PC. The <ncpus>64</ncpus> tells BOINC to run 64 threads on your PC.
<cc_config>
<options>
<start_delay>30</start_delay>
<ncpus>64</ncpus>
</options>
</cc_config>

After downloading the maximum of 384 tasks, edit the cc_config back to the number of actual cores of your CPU and click "Read config files" under the "Options" menu of the BOINC manager. Remember to do this.

Then "Suspend network activity" so that completed tasks will not be sent to the server.

Enable the network "Network activity always" when the event starts.

Alternatively (second method) to prevent completed tasks from being uploaded to the server, edit the Windows "hosts" file in C:\Windows\System32\drivers\etc folder. You may need to disable the antivirus first and launched notepad as an administrator.
In the hosts file, add this line "127.0.0.1 numberfields.asu.edu" and save. It seems to work when I tested it out. Just to be sure, check your completed tasks to ensure that it is not being uploaded to server. This is useful in the event that you need to download/upload tasks from a totally different project

2. Bunkering technique #2. If you finished all the 384 tasks early and want to bunker more, install virtualbox from Oracle website https://www.virtualbox.org/. Make sure that in your BIOS, the CPU Virtualization is enabled first. To install virtualbox on Windows 7 machine, see youtube video. You can install Windows or Linux.


3. Bunkering technique #3. Creating multiple BOINC instances. More to come....

Special Apps, Optimized Settings, Etc.
None.

Does anyone know if NumberFields is a "HT On" or "HT Off" project? Just realized most of my boxes have HT disabled from running Amicable.

I would imagine they would benefit from it. My Google fu isn't turning up much so if they didn't I am sure someone would have mentioned it by now.
