The only part I'm not getting is WHY the RS/6000 would have been the machine for "compute intensive scenarios". Given that they were/are running on essentially the same processor. Internal IBM politics? Or OS tuned better? | | Regards, Martin | [1] http://www.it-director.com/article.php?id=2416 I found this linked | to from one of the Linux news sites I read. With the advent of Linux on | iSeries, the iSeries seems to be getting mentioned in the Linux press | much more often. No bad thing for either platform (IMHO). I agree. Now, I'm not over-sold (to put it mildly ;-) on Linux. But I'm REAL glad to see iSeries in the Linux press...! Yer lucky I don't have time to get into the other subject. ;D ! (Plus, I hope to keep you in suspense until (if and when) Chapter 1 comes out...!)
