Supercomputers bulk up on power while losing price pounds

| Two years later, the number of processor cores in the Top500 systems had
| jumped to 732,500. And when the academic researchers who compile the list
| released the latest version at SC07, the number of cores had reached
| 1,648,095.

| Picklo, who oversees clustered Linux and Unix systems with a total of 1,650
| processor cores, said that the vendors of HPC applications aren't keeping up
| with the shift to multicore chips. According to Picklo, many software vendors
| still base their pricing on the number of processor cores in a system. The
| problem, he said, is that quad-core processors don't necessarily deliver
| performance equal to that of four single-core chips.

Maximum Wait for MinWin, Windows 7.0

| Frankly, the industry isn’t waiting around for Microsoft to fix its problems
| this time around. Companies like Tech Data have introduced Macintoshes — yes,
| Macintoshes — with downgrades to Windows XP preinstalled. And Dell downgraded
| some of its customer offerings to XP before introducing Ubuntu Linux on a
| handful of systems. And Apple’s market share continues to rise.
| Sure, Windows still dominates the market. But customers aren’t exactly
| demanding Vista by name.
| Enter MinWin. To Microsoft’s credit, the company realizes that it needs to
| get away from bloated Windows releases. But this is a long-range strategy,
| folks. When the trade press starts predicting that a distant Windows release
| will correct current Windows problems, it’s time for all of us to demand a
| reality check.


Linux in more than 90% of top supercomputers

What Intel Giveth, Microsoft Taketh Away

| “What Intel giveth, Microsoft taketh away.” Such has been the conventional
| wisdom surrounding the Windows/Intel (“Wintel”) duopoly since the early days
| of Windows 95. In practical terms, it means that performance advancements on
| the hardware side are quickly consumed by the ever-increasing complexity of
| the Windows/Office code base. Case in point: Microsoft Office 2007 which,
| when deployed on Windows Vista, consumes over 12x as much memory and nearly
| 3x as much processing power as the version that graced PCs just 7 short years
| ago (Office 2000). * * *

Windows for Supercomputers needs less memory than Vista

Testing Vista's different memory configurations

| You simply cannot play games on Vista with 512MB o memory, at least not the
| games wen tested. You will sometimes get playable scores but even then the
| experience and the load time will be ridiculous.
| Anything more than 512MB will help you a lot, with 2x1GB being the best
| price performance buy.
| 4x1GB is the best choice for best raw performance. It is hard to prove it

Vista Runs Smooth Only on 2G Memory

| However, Dell CEO Kevin Rollins suggested otherwise on Thursday, 26 Oct at

| Vista: Facing a Slow Adoption. In the beginning, early adopters and

| will be best suited for those ready to make an investment in the

| Considering how many software and game titles will likely need to

| the board, I would suggest really looking at what Vista's advantages
| are before taking the plunge.
| No matter how much we may wish to see the path Vista is about to
| embark on, the fact remains that because of its hardware requirements,
| Vista adoption may turn out to be rather slow.

Microsoft Windows Is A Greedy Memory Hog, The Cure Is To Feed It RAM

| For Windows 2000, XP, 512MB is the minimum and 1GB or more is recommended.
| For Windows 98 any flavor, 256MB is the minimum and 1GB is recommended. If
| you are an avid PC gamer or video editor, 1GB is the minimum
| recommendation. Other operating systems such as Linux or Mac are similar.
| Simply put: more is better.
