It is software from Intel for Intel systems.
"Yusuf Motiwala" wrote in message om... Hi, I downloaded eval copy of VTune 7.0 and surprised to know that I can't do event based sampling on Athlon systems. VTune documentation says: "EBS can be run on the Intel. Pentium. Pro, Pentium. II, Pentium. II XeonT, Celeron., Pentium. III, Pentium. III XeonT, Pentium. 4, and Itanium. processors. The processors' performance counters can be configured to monitor one or more events" Is this Vtune or athlon limit? My system is Athlon XP 2000. Regards, Yusuf |

Look, why should Intel work for AMD?
It is obvious that they will not support their only and greatest competitor. Just go to the AMD site and download the equivalent. "Yusuf Motiwala" wrote in message om...

VTune Event based sampling and Athlon XP
VTune is made by Intel, the Athlon processor is made by
*gasp* a competitor. What do you think? |

Just about everything intel does to advance their own platforms helps AMD
already (compilers, platform design, etc.). I bet that if you use Vtune on software written on and Intel system it will improve the performance on an AMD system as well (maybe not as much though). "David Schwartz" wrote in message ... "Kevin G. Rhoads" wrote in message ... VTune is made by Intel, the Athlon processor is made by *gasp* a competitor. What do you think? Intel wants to sell VTune. VTune is more expensive than almost any single Intel CPU. It would make more sense for them to support their competitor's CPUs to sell more copies of VTune. DS |

It would be trivial to add support for the Athlon, but for some unknown reason g they don't want to. I thought I saw a non-Intel patch to do this somewhere a while ago (gave the same counters as a P2 or PPro or something), but I google doesn't seem to know about it. -- Michael Brown www.emboss.co.nz : OOS/RSI software and more Add michael@ to emboss.co.nz - My inbox is always open |

Does AMD has equivalent? I suppose Vtune should support any processor
if it can support EBS counters. "jacob navia" wrote in message ... Look, why should Intel work for AMD? It is obvious that they will not support their only and greatest competitor.

"jacob navia" wrote in message ... Look, why should Intel work for AMD? It is obvious that they will not support their only and greatest competitor. Just go to the AMD site and download the equivalent. If Intel makes VTune not work with AMD CPUs, then Intel is leaving the market for performance analyzers and tuners for AMD CPUs all to AMD. That would be pretty foolish of them since they have a product that could compete in that market. Look at it this way, if you have an AMD CPU, Intel has lost the sale of a CPU to you. That's what, $200 or so? But they can still sell you VTune. That's what $1500 or so? Would they rather you buy an Intel CPU and an AMD performance tuning tool? Don't you think they'd rather AMD not have the $1500 and they have it instead? Your post is a senseless knee-jerk reaction. DS |

DS If I were in charge of Intel, I'd be giving away VTune because there's a lot more people who buy CPUs than there are who buy, or even use, development software. It's in Intel's interests to have all software written running exceedingly well on their CPUs and.. not so well on those made by their compeditors. With all other things being equal, given a choice between an Intel cpu and a comparitable AMD cpu which would you choose knowing that your favorite software will run significantly faster on the Intel cpu? But if you can get developers to pay for software which helps your company sell more CPUs... all the better. ;/ regards, -Brent doomsday AT optusnet DOT com DOT au |

However, Intel doesn't give away VTune, they charge quite a bit for it. This suggests that your interpretation of Intel's interests is wrong. You don't think Intel's management is stupid, do you? It's in Intel's interests to have all software written running exceedingly well on their CPUs and.. not so well on those made by their compeditors. That's certainly true. The CPU market is much larger than the performance tuner market. With all other things being equal, given a choice between an Intel cpu and a comparitable AMD cpu which would you choose knowing that your favorite software will run significantly faster on the Intel cpu? Except that 90% of what you do with VTune helps AMD CPUs too. Intel is just trying to eliminate clumsy coding in a market that it controls most of. But if you can get developers to pay for software which helps your company sell more CPUs... all the better. ;/ Is it better? Doesn't it mean fewer people will performance tune their programs for Intel CPUs? And doesn't it leave AMD room for people who have AMD CPUs to use only an AMD performance tuner? I'm afraid your analysis leads to inconsistencies. Put it this way. Assume that VTune only (or mostly) tells you about things that cause performance problems on Intel CPUs. And assume that there are far more users than devlopers. Why should Intel particularly care what processors developers use? Wouldn't they rather developers with AMD CPUs could still optimize code to run better on Intel CPUS? DS |
