What exactly is a P-state? (Pt. 1)
By Taylor Kidd (Intel) Posted on 04/06/15 6
    A P-state is a voltage and frequency operating point       What is a P-state? When someone refers to a P-state, generally only the frequency is talked about. For example, on my Intel® Core™ processor, P0 is 2.3 GHz, and P1 is 980 MHz. In truth, a P-state is both a frequency and volt...
C-states and P-states are very different
By Taylor Kidd (Intel) Posted on 04/06/15 13
C-states are idle states and P-states are operational states. This difference, though obvious once you know, can be initially confusing. With the exception of C0, where the CPU is active and busy doing something, a C-state is an idle state. Since an idle CPU isn't doing anything (i.e. any usefu...

Parallel Image Processing in OpenMP - Image Blocks
By Royi5
Hello, I'm doing my first steps in the OpenMP world. I have an image I want to apply a filter on. Since the image is large I wanted to break it into non overlapping parts and apply the filter on each independently in parallel. Namely, I'm creating 4 images I want to have different threads. I'm using Intel IPP for the handling of the images and the function to apply on each sub image. I described the code here: The problem is I tried both sections and parallel for and got only 20% improvement. What am I doing wrong? How can I tell each "Worker" that though data is taken from the same array, it is safe to read (Data won't change) and write (Each worker has exclusive approach to its part of the result image). Thank You.

Hi, In our university bought a machine with CO-PROCESSOR PHI. The description in the site: It is reported that there is no support JAVA yet. The answer is 2013 and we are already in 2015. Is there a Java option for coding? Tks Rafael
Intel® Xeon Phi™ Coprocessor Developer Training Coming to a City Near You in 2015

Mixing kernel space and userspace in a new kernel.
By Jog L.0
Hello, I was thinking of creating an open source kernel (with block already written in the linux kernel obviously). Now I would like to hear from experts what are the dangers to run in ring0 if no users and no external connections are done. We are in a situation in which the processor is isolated from the whole world. No one can mess with it. all the processes running on top of it have to register and are created and compiled by root using a specific memory range. No process can be launched without the acceptation of root. No human accesses it. The code running inside is reviewed and we have facilities to be sure no other memory range than the one we expect each process to use can be used. That is for the -restrictive- context. Now, could we imagine it be possible for such a kernel to exist or are there some limitations that I don't predict ? The kernel is to be massively specialized, hence the "almost starting from scratch". Thanks for your insights, Jog
linking with two versions of mkl (multi threaded and single threaded) in one application
By Michal K.3
Hi, Is it possible to use both the single threaded version of mkl library and the multi threaded version of mkl in one application? I need the single threaded version to use with PLASMA library, yet at some other part of my code, I need use mkl PARDISO, for which I need the multi threaded version. Any help will be greatly appreciated. Cheers Michal
