The application, Xwin-nmr, runs in a node-lock mode in each spectrometer,
with only 64 MB. The CPU is R4600PC on one and R5000 PC on the other. There
is a noticable difference in speed between the two CPUs.
Question #1 : X -display-servers link up:
I plan to set up to each console workstation, one X display server for
light duty 1-D and 2-D data processing.
The display server will be a old SGI indy (R3000PC) workstation on the
R4600PC console workstation.
On the R5000PC console workstation, I intend to use a PC at 160 MHz with
4M Vram, the X display server in the PC will be Exceed.
>From what I heard, the workstation of the console (the client being
Xwinnmer) cannot handle more than two to three Xs! What is your experience
and advice on this aspects with the INDYs ?
Question #2:
I plan to buy a new SGI-O2 and use it as a standalone workstation runing a
third node-lock Xwinnmr. I don't have all the money to buy up all the
goodies. Can you suggest what will be the close to ideal configuration on
memory and others ?
Question #3:
As my current license on Xwinnmr is node-lock single user format. Only one
user ID can process their data at a time. The other user on the Xdisplay has
to use different Logname. When you have sixty or so users, how would
you handle their accounts? More specifically, would you give them
individual account?
or
Would you let each research group share two or three accounts (LOGNAME)?
Remarks:
I have tried to assign users (different lognames) to a same GROUP, Xwinnmer
will allow them to process data, but they cannot plot out their spectra! I
guess it is due to the write permission within the Xwinnmer structure.
Thank you and I will be glad to share all the feedbacks upon request.
Sincerely
Yiu-fai
