The function accounts for hyperthreading by multiplying the physical core count by 2. .EXAMPLE Get the total number of logical CPU cores $cores = Get-CpuCore Write-Host "System has $cores logical CPU cores available" #> function Get-CpuCore { [CmdletBinding(DefaultParameterSetName = '')] [System.Diagnostics.CodeAnalysis.SuppressMessageAttribute('PSUseSingularNouns', '')] param() begin { # initialize counter for tracking total physical cores $totalPhysicalCores = 0 Microsoft.PowerShell.Utility\Write-Verbose 'Initializing CPU core count calculation' } process { # query physical processors through WMI $processors = CimCmdlets\Get-CimInstance -Class Win32_Processor Microsoft.PowerShell.Utility\Write-Verbose "Retrieved $($processors.Count) physical processors" # sum cores from each processor $processors | Microsoft.PowerShell.Utility\Select-Object -Property NumberOfCores | Microsoft.PowerShell.Core\ForEach-Object { $totalPhysicalCores += $_.NumberOfCores Microsoft.PowerShell.Utility\Write-Verbose "Added $($_.NumberOfCores) cores from processor" } # account for hyperthreading $logicalCores = $totalPhysicalCores * 2 Microsoft.PowerShell.Utility\Write-Verbose "Final count: $logicalCores logical cores" } end { return $logicalCores } } |
