#2537: sim setup-silent produces float values for ppn in machine.ini file
Reporter: Roland Haas
   Status: new
Milestone: 
  Version: development version
     Type: bug
 Priority: critical
Component: SimFactory
Running `sim setup-silent` on a freshly updates macOS BigSur x86 VM I get:
```
% ./simfactory/bin/sim whoami
Error: value for key ppn in section osx-homebrew is not of required type int
Aborting Simfactory.
```
On that system python3 happens to be Python 3.8.2.
This can be fixed by:
```diff

diff --git a/lib/simdt.py b/lib/simdt.py
index 6b51053f..c1a63cea 100644
--- a/lib/simdt.py
+++ b/lib/simdt.py

             if platform.system()== 'Darwin':
                 SocketsPerNode = int(cpu_info['hw.packages'])
-                CoresPerSocket = int(cpu_info['hw.physicalcpu']) / SocketsPerNode
+                CoresPerSocket = int(cpu_info['hw.physicalcpu']) // SocketsPerNode
             else:
                 CoresPerSocket = int(cpu_info['Core(s) per socket'])
                 SocketsPerNode = int(cpu_info['Socket(s)'])
```
which should be backported.
