HPC Cluster Problems

從 ipyparallel/apps/launcher.py 和 ipyparallel/apps/ipclusterapp.py 開始，沿著 WindowsHPCControllerLauncher 的路徑追蹤到失敗的 job.EXE 提交命令。檢查 /scheduler 值和 ipcontroller_job.xml 是如何組裝的，然後重現提交失敗，並記錄或修正 controller 的啟動行為，讓 Windows HPC 叢集啟動完成。

Hey guys very very cool job so far.

I'm not quite sure if that's a hugh issue, but I wasn't able to find a solution by myself.

Goal: I want to implement a pythoncluster on a Windows HPC Cluster

Installed SW: Windows Server 2012 on the Head, HPC Pack 2016 as managment, and Anaconda for management of python.

What I have done so far: Installed all ipcluster dependencies and made a cluster ( ipcluster start -n 2) working without issues. I did not establish connections to any engines yet. I thought that would minimize fault potentials.

Anyway when I'm trying to use the WindowsHPC controller, The cluster does not start up, but fails with:

I thought about wrong paths, but unfortunatly this wasn't a problem. I guess the problem isn't that big but I couldn't dig to the source. I tried to highlight the most intersting part of the message.
