Profiler for loops that make good candidates for offload.

Hi all,

I am running an application known as CESM.

I tried various profiler Intel(itac and also Vtune) and non intel(TAU and others).

However I have not found any suitable profiler which can suggest loops that make for good candidates for offload or vectorization.

the --profile-loops options do not run on parallel application and CESM takes eternity to complete if I try to run it as MPI-serial.

Any suggestions?

thanks in advance.

How to change mac address of each mic device?

I'm using MPSS 3.4.3 on windows.
I challenged to change  mac address of each mic device by modification of "micN.xml".
But, it failed.

I tried following step.
1, Modify mac address term of "micN.xml".
2, micctrl -r
3, micctrl --start
( I also tried PC reboot. )

How to change mac address of each mic device?

Thanks,

DH77 motherboard

I am attempting to get KNC (7120) working in a Win7 x64 system that is based on a DH77KC motherboard.

System boots and I can get into Windows, but the card is not usable, because it is listed in the device manager with a status: "This device cannot find enough free resources that it can use. (Code 12)"

It is the only card physically plugged into the motherboard (I'm using integrated video). I've disabled most nontrivial devices through BIOS, up to & including front panel USB, with no effect.

Parallel Studio XE Requirement

We are deciding between the professional and cluster editions for use with a pair of Phis.

Is it mandatory to get the Cluster edition, or will the Professional edition suffice? The only differences seem to be Intel MPI related.

Would we not be able to use, for example GCC OpenMP? Could we instead use something like TBB?

Working with Intel® Code Builder for OpenCL™ API on Systems Equipped with Intel® Xeon Phi™ x100 Coprocessor

Due to the recent restructuring in OpenCL™ Technology (see https://software.intel.com/en-us/intel-opencl ), the Intel® Code Builder for OpenCL™ replaces the Intel® SDK for OpenCL™ Applications. For the Intel® Xeon Phi™ x100 coprocessor, that means we need a specific OpenCL™ Runtime and the Code Builder for the coprocessor. So I decided to install the new OpenCL development environment and test an application on the Intel® Xeon Phi™ x100 coprocessor (codename Knights Corner).

针对“普通级(以上)厨师”的高级计算机概念: 简介

之前在与一位非常聪明但不是专业工程师的同事交谈时,我发现有必要对线程化和英特尔® 至强融核™ ⅹ100 和 ⅹ200 架构的其他组件稍作解释。 首先关于超线程,(说的更具体一点)以及协处理器的超线程版本。 经过冥思苦想,我终于想到可以用公共厨房来进行恰当的比喻。
