Who needs GPU compute?

[numerobis]

yes, very nice... but i don't want to see the price tag...

and this sounds not that good to me "...includes at least 8GB of GDDR5 RAM. The card runs an independent Linux operating system that manages each x86 core..."

I was hoping for a solution that uses the normal system RAM... but i think this is not possible with PCIe and so many cores. But a card with 16 or 32GB... 10000€, 20000€?!?
And if it runs linux what does this mean for the coding? I thought the biggest advantage should be that the code doesn't have to be changed (or not much) but we'll see...

It has been officially presented yesterday... and the prices too...

The passively cooled Xeon Phi 5110P is shipping for revenue at Intel now, and will be generally available on January 28 to the rest of us for $2,649. The actively cooled Xeon Phi 3120A card, which is hotter and yet has less memory and bandwidth, will be available sometime in the first half of 2013 with a price that is expected to be around $2,000.

Performance compared to a Dual Xeon E5-2670 2,6GHz (2x 8 cores hyperthreaded = 32 threads):

if the scaling is as linear with simply recompiled x86 application code then it will be a very interesting choice.. however i have not found out if the on-board memory limitation (max 8gb for these models) is as relevant for Phi as it is for cuda cards or if there is a way to "swap/include" main memory more efficiently.

because a 8gb won't do the job...

What does it take to code for a Xeon Phi?

What will Intel Xeon Phi do to the GPGPU market?

[macray]

pricing will be around 2800€ according to a german it news site... but not yet available - so this might still change when they are released.

would be nice to see Maxwell running on such thing. Will that even be possible?

For a virtual machine it seems to be possible to access the complete memory of a system

ScaleMP, a leading provider of virtualization solutions for high-end computing, is announcing that vSMP Foundation now supports Intel’s Many Integrated Core Architecture (Intel MIC Architecture) including first commercially available product from the new Intel Xeon Phi product family, codenamed “Knights Corner”, scheduled for production in second half of this year. vSMP Foundation creates a single virtual machine (VM) representing all the cores and memory of the host system as well as the Intel MIC architecture based Intel Xeon Phi coprocessor. The VM gives developers and users access to the entire compute and memory resources (host processor and Xeon Phi coprocessor) from a unified execution environment. This new paradigm allows for hundreds of cores to be used in a heterogeneous environment to run any x86 applications. Large numbers of cores and hundreds of GB of memory can be dedicated to a single application, using traditional shared-memory programming model.

not sure what this means for normal systems...

GREAT!
That would be so great for MW!!

Would love to see Phi or CUDA enabled Maxwell!

Not sure about the complexity of these "tests" and how they compare to rendering operations, but...

Intel announces 14nm Knights Landing processor in Xeon Phi update

It is unclear whether this will be Intel's first 14nm chip, as the company declined to indicate an availability date for the product. An update of Intel's mainstream Core chips codenamed Broadwell was expected to debut on 14nm later this year, but recent press coverage has suggested this may be delayed until sometime in 2014.

However, Hazra did disclose that Knights Landing will be able to operate as a CPU in its own right, while the current Xeon Phi products are designed as PCI Express coprocessors that work in concert with standard Intel CPUs.

Intel announces 14nm Knights Landing processor in Xeon Phi update

Yes, the real one... 2014 could be an interesting hardware year: Knights Landing, Haswell-E, Broadwell and nvidia's Maxwell
