# PSParallel

Invoke scriptblocks in parallel runspaces

## Installation

```PowerShell
Install-Module PSParallel
```

```PowerShell
# ping all machines in a subnet
(1..255).Foreach{"192.168.0.$_"} | Invoke-Parallel { [PSCustomObject] @{IP=$_;Result=ping.exe -4 -a -w 20 $_}}
```

Variables and functions are captured from the parent session.

## Throttling

To control the degree of parallelism, i.e. the number of concurrent runspaces, use the -ThrottleLimit parameter

```PowerShell
# process lots of crash dumps
Get-ChildItem -Recurse *.dmp | Invoke-Parallel -ThrottleLimit 64 -ProgressActivity "Processing dumps" {
[PSCustomObject] @{ Dump=$_; Analysis = cdb.exe -z $_.fullname -c '"!analyze -v;q"'
}
```

The overhead of spinning up new PowerShell classes is non-zero. Invoke-Parallel is useful when you have items with high latency or that is long running.
