We release versions of the software which have gone through a security review. Also, as you mention 7.3.x is a beta release with changes daily to the source code. As for 64 bit or 32 bit recommendation, we choose the 32 bit version because every computer running windows can use that version of the client. But if we were to recommend the 64 bit not every computer would be able to run the client. A 32 bit client on a 64 bit machine will try to download 64 bit science applications even though the agent is 32 bit. Also, the differences between 7.2.42 and 7.2.47 are minor, but one of the changes is a fix to a screen saver bug that was discovered during our testing. Thanks, -Uplinger So why don't you also TEST both version for Win...the x86 (32bit) and x64? Most of new people are running x64 versions of Win7/8 'cause they need more than 3GB of RAM... ;) Because the 32 bit version runs in 64 bit OS'es too.  - AMD Ryzen 5 1600AF 6C/12T 3.2 GHz - 85W - AMD Ryzen 5 2500U 4C/8T 2.0 GHz - 28W - AMD Ryzen 7 7730U 8C/16T 3.0 GHz |

U still don't get it...32bit can allocate only 3GB of RAM! even if you have 32GB on a x64 sys...32bit can allocate only 3GB!  |

See my previous reply / query at technicians really. The agent just controls the science apps as in run / stop / report etc. The science apps are a process into their own doing the memory requirement requests. If 64 bit then they can go above 3gb on windows I'd think where each runs in their own isolated memory block.
----------------------------------------Notably, i've run 8 CEP2 concurrent with the wcg 32 bit agent on a 64 bit W8. Total memory+swap often far exceeded the 3gb limit. Not recommended as all that swapping really dropped the efficiency in this 8gb system. [Edit 1 times, last edit by Former Member at Mar 27, 2014 2:28:25 PM] |

Apis, The upgrade path is very simple, just download and install over the top of the previous version. It should prompt you to reboot after the install is complete. Once that is done, you will be running the latest version of the agent. The work units do not need to be completed, they will restart from checkpoint after reboot. Thanks, -Uplinger also, if we have used x64 app in Win7...meaning that the app was in :\Program Files\BOINC... and to update to 32bit app in Win7...meaning that it would go into :\Program Files (x86)\BOINC directory... does that mena we can just install x86 app over the x64? |

Switching agent bit size would call for a recommendation to uninstall first. The data directory can remain in same place, just point to it when installing the different version. Done swapping back and forth without uninstalling before on a w8-64 system and it had no impact on the task proceedings.

In short lavaflow is correct.
Long explaination: There is generally a system maximum of 3 GB on a device with 32bit Windows. This means that if you have a 32 bit processor on a standard windows machine it will only recognize up to 3 GB of memory on the system even if you have 64 GB of physical memory installed. Each application run within Windows 32 bit has a maximum memory space they can use up to 2GB unless they have IMAGE_FILE_LARGE_ADDRESS_AWARE set which I do not believe our science applications have. If you are running BOINC 32bit on a 64 bit system, the BOINC client (boinc.exe) can only use up to 2 GB of memory, however the 32 bit BOINC client running on my Windows 7 64 bit machine is only using 28 MBytes of memory. WAY below the 2 GB limit. The 32bit version of the BOINC client can call 64 bit processes and open them in which case each of those science applications (wcgrid_mcm1_7.32_windows_x86_64) can use in theory up to 8TB of memory. However most of our applications have a memory foot print well below 1GB. Examples: Running 32 bit windows and 32bit boinc with 16 core machine and only 3 GB of RAM (ignore pagefiles...beyond scope of example). I can run 16 science applications running 32bit on each. Each application can use up to 2 GB of memory but only use 1MB of RAM. This would work as the limit on the 3GB RAM is hit, which would cause application out of memory errors. Example2: Running 64 bit windows and 32bit boinc with 2 core machine and 8GB of RAM. BOINC can run either 64 bit or 32 bit applications. In this case you have downloaded 2 - 64 bit applications, and each has a theoretical limit of 8TB of memory but actually only use 3GB each. This would work again as both science applications are under the 8TB and combined they don't use up your system memory. Note: Yes i know in my examples I don't take into fact that other processes are running on the system. which use up some of the total system memory. Thanks, -Uplinger |

@Uplinger:
The upgrade went very smoothly. I didn't even have to reboot my machines. However, I believe that it's important to tell volunteers that tasks will be restarted from the last checkpoint. Those who don't really understand this will probably be reassured, but if they do understand and are running CEP2 on a slow machine they need to know as they could lose many hours of work. |

Apis,
Great to hear. I will let the team know your suggestion on an FAQ or something similar for upgrading the agent. Thanks, -Uplinger |

U still don't get it...32bit can allocate only 3GB of RAM! even if you have 32GB on a x64 sys...32bit can allocate only 3GB! Lavaflow already explained it. The client does not allocate memory. The science apps do so and if they are 64 bit, which a 32 bit BOINC client can manage, they will as much memory needed/available. - AMD Ryzen 5 1600AF 6C/12T 3.2 GHz - 85W - AMD Ryzen 5 2500U 4C/8T 2.0 GHz - 28W - AMD Ryzen 7 7730U 8C/16T 3.0 GHz |
