Known Limitations and Workarounds for the Microsoft Windows Platform

• The installation of Services For UNIX 3.5 requires a good administrative understanding of the Windows platform and it's integration into a UNIX environment. Appendix A of the N1 Grid Engine 6 Update 4 Installation Guide provides on Overview of SFU. Further technical information and documentation about SFU can be found on the Microsoft web server at http://www.microsoft.com/windows/sfu/default.asp.

  Username mapping, NFS mounts, and hostname resolving in SFU require special attention to successfully install the Grid Engine execution daemon, submit host functionality, and integration of Windows hosts into a N1 Grid Engine cluster.

• Installation of a Windows host in a N1 Grid Engine cluster with CSP mode enabled is currently not yet supported because it is untested. Full support for this functionality will be provided in June.

• The execution daemon cannot start jobs of users who are members of a Windows Domain. A fix for this problem is currently in progress in will be delivered in June 2005.

• On machines with more than one processor or Hyperthreading processors, only one processor is detected by the load sensor. This does not limit the use of multiple CPU's by jobs running under N1 Grid Engine on Windows. If a queue instance is created during the installation of a Windows execution host, the number of queue slots for this host can be changed after the installation.

• A Windows execution host cannot be installed with the auto installation procedure.
