Parallel Image Processing in OpenMP - Image Blocks
Di 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: http://stackoverflow.com/questions/29319226/parallel-image-processing-in... 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.
COPROCESSADOR PHI AND JAVA
Di Rafael R.2
Hi, In our university bought a machine with CO-PROCESSOR PHI. The description in the site: https://software.intel.com/en-us/articles/intelr-xeon-phitm-coprocessor-... 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

Mixing kernel space and userspace in a new kernel.
Di 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
