Letters to the editor
We use a SPARC-1000 server with 4 CPUs and Solaris 2.5 OS. I want to improve the performance of our Verilog simulator. May I distribute each Verilog run to each CPU?

The system will automatically optimize the placement of four Verilog runs on your four processors. You don't need to do anything to help it.
If you want to have a single verilog run use four processors, you need a multithreaded version of Verilog. You should ask Cadence about this topic, as I know that some EDA tools have been multithreaded.
Hi Adrian... I use ruletool a lot for tuning my 1000e's. We use SAS and oracle on these systems. They're all going to be replaced with ultra's soon. Can you do a brief reply on changing ruletool to work on the the new ultra's? It would be a great benefit for many, I'm sure.

You need to get version 220.127.116.11 of the SE toolkit, which supports Solaris 2.5.1 and the new Ultra servers.
Its been available since last June. See
I really enjoyed Adrian Cockcroft's March column. In fact, I downloaded everything he mentioned in the article. The only thing I'm missing is the java class for his graphing utility. This would be very helpful.

I found the graphing utility via Gamelan, the link from the percollator applet page http://www.sun.com/sun-on-net/www.sun.com/percol/Percapplet.html still seems to work, and gets you to
http://www-igpp.llnl.gov/people/brookshaw/java/ where the source is located. Its been updated since I last used it, so I'm not sure if it still works with the new version.
It was nice to see NetPerf mentioned in the press. However, there is a bit of confusion as to NetPerf's "vendor" status.
NetPerf is not really an "HP-designed benchmark." It is a benchmark that is written and maintained (something like a contributing editor more than an author these days) by an engineer who happens to work for Hewlett-Packard.
Letting an engineer continue to spend some time with NetPerf, and allowing space on an HP system connected to the Internet for the NetPerf database, is something HP does to keep one of its engineers happy. Namely me :)
How NetPerf works and such is decided by me and those around the Internet who contribute to NetPerf. As for the NetPerf database, management of that resides directly with me -- if HP marketing or such decides they want to "control" it (something I consider very unlikely) I'll just try to find some other site to host it. The site it is on today is as much a matter of convenience as anything else.
I hope this helps to clarify the status of NetPerf.
--Rick Jones, Hewlett-Packard
Thanks for the clarification. I was indeed under an erroneous impression, based however, on available materials.
Do you have any articles discussing how to setup and utilize single logical screen on a Sun using Solaris or SunOS. This means having 2 monitors on a single cpu with a single keyboard and a single mouse. The windows in one screen can be dragged to either monitor. Your help would be appreciated.
--Phillip Bruce, (firm indeterminate)
Your answer can be found in the Xsun man page. Try
openwin -dev /dev/cgsix2 -dev /dev/cgsix0
A button or hyperlink to take you to the same column in the next and previous month would make navigating through multi-issue articles much easier. Even in articles that are all in one issue, it would make it easier to, say, browse all the security columns in one shot.
I read SunWorld Online a lot, lots of good info. Thanks!
