DCT and Quantization are the first two steps in JPEG compression standard. This article demonstrates how DCT and Quantizing stages can be implemented to run faster using Intel® Cilk™ Plus. In order to see the effect of quantization on the image, the output of Quantization phase is passed on to the de-quantizer followed by Inverse DCT and stored as an output image file.
If you are using Intel® WS-Management Java Client Library in order to play with vPro Machines Logs, one thing that its missing from the examples its a way to get the username that try to perform a KVM session for example. So, the following piece of code can help you.
When colleting log, If Initiator Type == 1, so, we have the user from AD SID, using this SID we can retrieve all user info from AD.
in the KerberosSIDInitiatorType you have this information:
Intel® Cilk™ Plus is an extension to the C and C++ languages to support data and task parallelism. It provides three new keywords to implement task parallelism and Array Notation, simd pragma and Elemental Function to express data parallelism. This article demonstrates how to improve the performance of an Averaging Filter in image processing using Intel® Cilk™ Plus. To demonstrate the performance increase, you will use a program that reads a bitmap RGB image and does averaging with a filter of size 3x3. Averaging filter work
Performance tuning of an existing application is truly a challenge and it depends on a lot of factors like the nature of algorithm the application works on, if the implementation is scalable to take advantage of thread/data parallelism etc. The most logical approach any developer would follow for tuning the performance of an application is to do a dynamic profiling of the application under different workloads, try to analyze the hotspots in that application, and then fine tune them to work best on a given hardware architecture.
