CumuluxMX 64bit

[joseil]

Hi

Are there any plans to compile CumuluxMX as a true 64bit application. now most Operating systems are 64bit.
I recently moved CumulusMX to a new virtual envirioment (Proxmox) with a modern CPU and noticed a lot of x86/split lock detection warnings in my syslog courced by CumulusMX. For now i disabled x86/split lock detection to get rid of the warnings but that is not the way to go i beleef. So i'm hoping for a 64 bit version of CumuluxMX or that the application is updated so that x86/split lock detection is not tiggered by the CPU (Intel i7) of in my virtual envirioment.

Not currently, CMX is compiled as "Any CPU - prefer 32 bit". The constraint lies in the SQLite libraries which must be specified as either 32 or 64 bit. I have looked at the SQLite implementation in the past and come away thoroughly confused, even if you use the newer NuGet packages they all seem to rely on external pre-compiled core DLLs. I'll have another look one day and see if I can produce a true "any CPU" solution.

Hi Mark,

Thanks for the reply, hopefully in the (near) future 64bit

Hi Mark,

I noticed that 64 bit is now supported but after the upgrade from Cumulus MX v.3.23.1 build 3221 to Cumulus MX v.3.24.1 build 3234
Cumulus MX is still running as 32bit i tried it on the operating systems below
Windows 10 Pro 22H2
Windows Server 2022 Datacenter 21H2
The 32 bit sqlite3.dll is copied over to the root directory,Is there any configuration needed to run Cumulus MX as x64?
Or should it be detected automaticly?

Kind regards

I am afraid this is not true in the latest build, sqlite3.dll does not appear in the main release directory and can be deleted from an existing directory if you are copying over it.

There are two new directories in this release (x64 and X86) that have to be copied over (see the release notes) and the appropriate version is loaded from these libraries.

Hi David,

my observation:
when CMX starts it will copy the appropiate sqllite3.dll form the x64 or X86 directories to the root directory, see post 11136 from Mark.
So when CMX starts up i presume it does a OS check, but in my case it fails to detect a x64 operating system.

Might I suggest you check your CMX log file as on startup it shows if it is running 64bit. Below is an extract from mine which I know is Linux but should still show the process in Windows.

At least we will know what CMX thinks it is doing!

It's running as 32 bit, apparently CMX does not detect the OS correctly on windows

Hello Joseil, & all,
Mine also comes up saying 32bit when it should be 64bit.

My Computer details are,
System type: 64-bit operating system, x64-based processor
Edition: Windows 11 Pro
Version: 22H2
OS Build: 22621.1344

Windows error.png

I have also noticed that this Error: Unable to access the System Uptime performance counter. System uptime will not be available
Comes up in MXdiags what could be causing this?

Kindest Regards
Mike

I deleted the sqlite file in the root directory when I upgraded, and copied both x86 and x64 across, but mine also runs as 32 bit.

[broadstairs]

As a test I just updated my unused CMX install on Windows 7 64-bit and it starts as 32-bit on there as well. Does look like maybe however Mark is trying to detect 64-bit on Windows is not reliable but works fine on Linux. And yes the two extra directories were copied over (x64 and x86 as they did not exist on this old version).

OK, lets clear up a few things...

CMX does not test the OS for bitness - it doesn't care about that.
CMX does test if it is running as a 32 or 64 bit app.
CMX cannot control how it is launched, vis-a-vis 32 or 64 bit, which is down to the .Net Framework.

It does run as a 64 bit app on my Windows 11 machine...

So, the question is why not on some?


Two quick checks on your systems if you would....

What is the value of your registry entry: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\Enable64Bit

And what is the output of the command: %windir%\Microsoft.NET\Framework64\v2.0.50727\ldr64.exe query

On my Windows 7 system see attached screenshots.
