shrike 0 Posted November 3, 2003 Hi, we are currently planning the purchase of new server hardware. As AMD Opteron servers got raving reviews in terms of sheer performance even for 32 bit Software (eg OFP) we would probably switch from Xeon CPUs to a dual Opteron System. Now, does anybody have an idea if we're sailing right into trouble with this one? Would OFP dedi server run properly in a Linux 64 bit OR Win2003 64 bit environment? Any clue about the performance hit/gain we can expect? I'd be happy to read some comments from people who actually know what they're talking about, unlike me  Thx in advance Shrike Share this post Link to post Share on other sites
vesuvio 0 Posted November 3, 2003 Hello Shrike For your questions read article at this link http://www.osnews.com/story.php?news_id=4618 Bye Vesuvio [McY] p.s. Ofp isn't optimized for run on machine not 32bit cpu. Share this post Link to post Share on other sites
shrike 0 Posted November 3, 2003 Hi Vesuvio, thx for your reply although: Quote[/b] ]http://www.osnews.com/story.php?news_id=4618 This guy seems not to have all the facts at hand, as many of the comments to the story prove him wrong (see 32bit translation or native) Furthermore we're talking about a "turnkey" system from IBM which I hope is tested thoroughly before it's released to the market: http://www.pc.ibm.com/us/eserver/opteron/325/index.html All I'd like to know is whether it runs without crashing and if it would be a significant performance upgrade compared to the Xeon 2.2 we're using now.

We did not test this, and I am not aware of anyone else who did. Moreover I know almost nothing about how 64b Linux handles 32b application. Quote[/b] ]as many of the comments to the story prove him wrong (see 32bit translation or native) I am afraid you get him wrong. He is not telling 32b code is emulated on Opteron, rather 32b system calls need to be translated to 64b ones (which seems natural condtion with 64b OS). It is very likely you can expect slightly better performance with 32b OS for some 32b applications, even when running on 64b CPU. Share this post Link to post Share on other sites
KaRRiLLioN 0 Posted November 3, 2003 You'd probably get pretty good performance running a 32b OS on the Opterons, maybe even better than the Xeon. I've seen a lot of benchmarks for games, etc. running on the Athlon64's and the Opterons, but I haven't seen many for 32b server OS's running on them yet. That might be the best thing to check out. I purchased a Dell Xeon 3gz, 2MB cache, 1.5GB ram 1ru server for OFP, and that's worked pretty well for the most part. Some missions really eat the CPU cycles, however, so maybe when OFP 2 comes out BIS will consider a 64-bit multi-threaded dedicated server. Then I'll get an 8-way Opteron box. ;) Share this post Link to post Share on other sites
