"Istanbul" Gets Kudos


The new Six-Core AMD OpteronT processor, codenamed "Istanbul," features improved I/O capability, up to 34% more performance in the same power and thermal envelopes, and a consistent socket.  But the real emphasis is on what that all means to our customers.

"I have to commend AMD on being able to bring a product to market that allows customers to leverage their existing Opteron server infrastructure rather than having to go out and buy all new servers, as it is with the Nehalem. This is a product that makes a lot more sense for the current economy where server sales have slumped by the major vendors by an average of 25 percent in in Q1 of 09 in comparison to the same quarter last year."
-Jason Perlow, ZDNet

"It is basically a "Shanghai" Opteron with 2 extra cores and a slightly tweaked memory controller. What is more impressive, though, is that AMD is capable of launching a hex-core at 2.6 GHz today, a CPU that consumes only a few watt more than the six month older quad-core at 2.7 GHz. Well done, AMD."
AnandTech: AMD's Six-Core Opteron 2435

"Two just-in reports suggest AMD has a success on its hands with its new 6-core Istanbul. Early tests are showing that the processor, which is a drop-in replacement on mobos supporting quad-core 'Shanghai' Opterons, delivers great performance while being very power-efficient."
-Alex Wolfe, InformationWeek

How Complex Is Your JRE Command-line? How Complex Is Your JRE Command-line?

As the AMD Java Labs works to improve JRE performance, sometimes our analysis leads to improvements that can be realized by tuning existing command-line flags. But here's AMD Java Labs' manager Ben Pollan's theory: "I bet most of you use few, if any, of these flags in production." So help us explore this theory by answering these two questions:
  - Do you set any command line flags in production?
  - If yes, what are they?

Just Released: ACML Version 4.3.0 Just Released: ACML Version 4.3.0

New features in Version 4.3.0 include:
  - Support for the Open64 compilers
  - Improvements in the performance of DGEMM and SGEMM
  - An experimental "fast memory allocation" scheme which may allow you to improve performance of the matrix-matrix multiply routine DGEMM
  - Tuning for AMD "Istanbul" processors within Level 1 BLAS routines and FFT routines
