Dear all, My adviser is going to purchase new server with AMD Opteron 2378 processor inside. Could anyone help me make sure that this processor is Opteron RevC and support IBS ? I really appreciate all the help. Thanks, Besar |

Hello Besar -- The Opteron 2378 is a third generation Opteron ("Shanghai"). As such, it will support IBS including the dispatch op sampling mode for IBS op sampling. This is the preferred IBS op mode since it produces a regular distribution of op samples and the distribution reflects the execution frequency of the basic blocks/instructions. The Opteron 2378 is stepping C2, so yep, it's RevC. Family 10h processors starting with RevC support the dispatched op sampling mode. Hope this helps -- pj Paul Drongowski Senior Member of Technical Staff AMD CodeAnalyst team Advanced Micro Devices, Inc. -----Original Message----- From: be...@cs...

Hi Paul, Thank you for your information, it greatly helps :). I have another question. Since the dispatch op mode is the preferred IBS op mode, I assume this is also the default mode when we do ibs ops sampling. Please correct me if I am wrong.
