Running cluster jobs from Windows requires 3 tools (curtesy of GW).
- Putty - a free telnet SSH client (whats getty?)
- WINCSP - a free ftp and transfer client
- Cygwin/X - a free X-Windows client (activate XWindows if you use setup.exe from cygwin)
...don't forget to start your Cygwin bash shell and enter startx
...enter your login name and pwd and enter the clustername in Putty and WINSCP, setup X11 forwarding in PUTTY, voila!
The Sun Grid Engine can be configured via qmon
The 8 GByte nodes on Shiraz can be accessed via qmon -q highmem.q
The Explorer style File Manager can be started on the head node with nautilus
