Hi Dave,

I am almost certain you'll hate this one :)

There are some patches (against 8.1.3) attached, to "improve" the sge_ca tool for managing CSP certificates; the aim is to allow overlap of multiple valid certificates.

Note that they change the behaviour of some existing options (-renew, -renew_sys, -renew_sdm).

What do you think?

I'm not running them in production yet so, even if you like them, you might want to wait a bit before putting them in a release.

Cheers,

Mark --

Hi!

I've got a problem with Grid Engine on Windows hosts and wanted to
check whether I'm missing something obvious or encountering a
bug. What I'm experiencing is that the usual GE environment variables
(including PE_HOSTFILE) aren't set when "-l display_win_gui=true" is
set. You can see the effect when you qsub

  /dev/fs/C/Windows/System32/cmd.exe /c "set S > c:\env.txt"

where "c:\env.txt" will contain all environment variables starting
with "S". With "display_win_gui=true" I don't see a single SGE_*
variable; without I get  SGE_CELL, SGE_ARCH, etc. like I expected. I'm
working with sources I've taken from darcs in June. Before upgrading
to 8.0.0c I've decided to review the diff: nothing in there seems like
fix to me.

I've traced the sources so far as to understand that
SGE_Helper_Service is used for the display_win_gui mode and that it
constructs an environment for the process. However I don't understand
the architecture enough to see how execd/shepherd pass information
into the helper.

My use case is a test of our Windows-GUI based application which can
initiate MPI computations. Without PE_HOSTFILE I fail to see how I can
find out which hosts I can use for the MPI run :)
