Hi Steve, we are running cadence, synopsys, mentor, ... tools (graphical and command line based) over sunray2fs and sunray3+ Clients very successfully locally and cross continent.
Sunray Servers are on sparc (m5000) and /etc/system sets the clock to 1000hz. As Compute Servers we mainly use the sunray Login Servers (sparc m5000), as well as some Linux boxes running centos.

What I see is: opening a cell layout, or panning around the cell layout using the Sunray3, takes ~8x longer than the same task on my 2011 i7 MacbookPro: =ssh to same Linux server, and run Cadence on the same cell data, on the same network. Also, the Sunray3 takes about 2x longer on the same task as from my Win7 PC with Xmanager/Xshell(xterminal) to the same Linux server. Now in both the Macbook case and the Win7PC case, there is local graphic processing, where the Sunray does not have much(any?) graphic processing. The Sunray3 just takes the pixel-data, that it receives( packed in UDP, I think ) and sends that to the monitor. So my question is, does this sound reasonable ? for CAD data to take that much longer to draw and pan, compared to a MacbookPro or a Win7 PC ? Note1, our SRSS was updated last fall, so I think we are up-to-date on the server software. Note2: I have tried this same experiment with two 10ZiG(PC-over-IP) thin clients(Tera1 and Tera2 chipsets), and I get the same results I get with the Sunray3. --> this leads me to believe the Sunray approach and the PC-over-IP approach(both sending pixel data over Ethernet) are not going to work with CAD data. Could it be the case that Sunrays were never intended to be used for CAD tools ? Or, is it possible we are missing some switch on the Sunray server that would improve the video performance ? thanks, -steve ------------------------------------------------------------------------------------------------------------------------------- {txaceray:~} uname -a SunOS txaceray 5.10 Generic_147441-01 i86pc i386 i86pc {txaceray:~} more /etc/release Oracle Solaris 10 8/11 s10x_u10wos_17b X86 Copyright (c) 1983, 2011, Oracle and/or its affiliates.
