I am using Parallel Processing Factor to speed up a process that has been taking too long. I have a question though. I have a workstation computer that has a 16-core processor. Each core has two logical processors. How many processes would it do if arcpy.env.parallelProcessingFactor was set to 50%, 75%, or 100%, given that fact?
every tool... including
has a section at the bottom of the help topic which states environment factors that are supported with an disclaimers....
Not valid for enterprise geodatabase
Yes I noticed. However, I am using ArcGIS 10.6. I do not have ArcGIS Pro, unfortunately. The bad news with that is that Parallel Processing Factor is not listed in the Environments section on the page for Mosaic to New Raster. That environment is only available starting with ArcGIS 10.7 for that tool. Bother.
The link that Dan Patterson gives clearly talks about number of cores ... "processes will be divided between hardware cores (processors) built into the machine". You say you have 16 cores then setting this environment setting to 100% will use all 16 cores. As that page never mentions "logical processors" I would assume it would mean that tools would not distribute work over 32 logical processors.
