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.

Known Limitations and Workarounds for GEMM

  • If the system time on the N1GE Master Host and the SCS Server are not the same, the job times given in the Monitor will not be correct. In particular, if the time on the Master Host is ahead of the SCS Server, then it would be possible to see negative jobs times. Please ensure that the system time on the N1GE Master Host and the SCS Server are the same.

  • A previous version of N1 Grid Engine 6, sold under the name "Sun Grid Engine Enterprise Edition 5.3", had an optional module that integrated with Sun Control Station 2.0 (the previous version of Sun Control Station 2.2). Customers using SGEEE 5.3 with SCS 2.0 who wish to upgrade to N1GE 6 with SCS 2.2 and GEMM should note that there is no automated upgrade procedure. You will need to uninstall SCS 2.0 manually from all the grid hosts, and then perform a fresh installation of SCS 2.2, followed by the installation of GEMM and subsequently N1GE 6.
