Best CPU for intensive programming and comprarisions with Integers with VS.Net


I'm in a company working in software that involves a lot of managing and operating with integers, it also requires constant comparisions between them. (jagged arrays full of integers that must be browsed quite a lot, comparing and operating them) Right now we are coding with <b>VS2013.Net C#<\b> (I know is not the best but... I can't choose). What might happen is that we change later on to make a small library with some core coding in C++ and other compiler, but thats a maybe far in the future...

I made a program to change user resolution.

Language is as follows. 

=> c, c++ , mfc


i have control by my app as follows,

=> back porch, front porch, scan speed, resolution etc


I have the drive to want to know i can control.


My applicationis not the CustomModeApp.exe .


I made a program porch, resolution, and want to control.


I wonder if ms visual studio 2013(c, c++, mfc) to create 


Please tell us how.


cpu => intel i5-4670 

graphic => intel HD 4600

Intel Architecture Code Analyzer Error

Hi everyone,

I am new here and it is my first post on this forum.

I just started using intel Architecture code analyzer (IACA) and when I tried to run it I had the following error as output:

"Initialization failed"

I looked in the Intel Documentation but I didn't find this error in their List.

Any kind of help will be really appreciated.

Many Thanks,


pass address to asm block


I would like to implement some AVX code manually using an asm block inside a function/program.

My question is the following : How do I pass an address from the standard C code to the asm block ? There is an example thereafter. I want to load the array 'a' and 'b' to registers, do an AVX add and then store back the result to the array 'c'. I know I could use avx intrinsics, it works that way but I would like it working using asm blocks.

rdrand failing on i7-4960x

I verified that it is supported on this chip by issuing CPUID, EAX=1, and find bit 30 set in ECX. However, when trying the loop below, RAX and CF are zeroed on first call and stay zero forever. I tried same code on an I7-4770K and it works fine, native and in a Hyper-V VM running on that system.

Does anyone know why this wouldn't work on the 4960x? Is something needed to kickstart the hardware rand generator?

PTP / IEEE1588 Support

We are looking to implement PTP on Windows with hardware timestamping from Intel cards.

It appears that Windows does not have a standard mechanism to obtain the 1588 hardware timestamps from the Intel NIC like Linux does. However, it seems that real-time-systems have been able to gain access to this info in some way: http://www.real-time-systems.com/rts-ieee-1588-precision-time-protocol-now-available-for-all-windows-versions.html
