Hi, We have recently started using the OmniThreadLibrary in our software to increase our scalability. It is showing great signs of doing this so far. We have today hit a major snag however. We tried running the code on a 96vCPU machine with 360+ GB of memory... The simple loop we are trying to create fails at the first hurdle with a 'Range Check Error', I traced this to the FNumTasks assignment. I can try and code around that but the loop then doesn't execute. Any clues? I can get an example up later if required. Thanks in advance, -- Peter.

So you are agreeing that it should be NativeUInt not DWORD 😄

I'm sorry but I don't understand? affMask receives the Result of 'Mask' which returns 'NativeUInt' not DWORD.... -- Peter.

OK, so just changed line 3755 of OtlCommon.pas to: affMask: NativeUInt; instead of: affMask: DWORD; and it's off and running... This has to be a bug no? -- Peter.

Well, this is weird... So I put together a test application to post... And it works... we must be pulling in something which is redefining an API call or something... I'll update if/when I find anything... -- Peter.

Happens with Just 15... I'll get some code up tomorrow. -- Peter.

Hi, It is 48 with 2 threads per core AWS Virtual Machine, m5a.24xlarge as specified here: AWS Specs Thanks, -- Peter.
