Intel® Moderncode for Parallel Architectures

Intel® Modern Code Developer Community

Intel launches the new Intel® Modern Code Developer Community - check out the new site.

The Modern Code Developer program applies multi-level parallelism as the framework, that uses all of the parallel performance features available on modern hardware via vectorization, multi-threading, and multi-node optimizations. Explore how to deliver multi-level parallel algorithms that effectively scale forward for today’s and tomorrow’s hardware.

If you do not think about your future, you cannot have one.
Everyone has a dream, no matter it can be come true or not. We just need 

a belief so that we know what kinds of way we can go. Although 

sometimes, we farther away the dream, and go to other way, and we know 

it it a life too.

NAMD segmentation fault when running with mpirun(intel 2015)

I had compiled NAMD 2.10 using intel 2015 compiler suite. I saw the benchmark for intel MIC card , so i am trying to benchmark NAMD with host processor only configuration. Though the following seems to me application related issue , but as i have used intel compilers  , so i have posted this issue here.
Presently i am benchmarking the application on my system (CentOS 6.5 ,Xeon 2670 v3), though i will incrementally add optimization flags as per my architecture.

Dramatic Performance Increase - Intel Hyperthreading

Hi,

In Task Manager I was able to see in the lower left corner HT stepping:1->2->3 (these numbers were changing in real time while application was executing) This was right next to CPU usage:%, passed time : nn, Physical memory. Application was really aware of Hyperhreading and was utilizing it. After reformat I cannot restore this magic performance boost. 

System:

Intel processor (i3 3220)

Windows 8 Single Language.

 

hybrid MPI+OpenMP

I am running a hybrid MPI/OpenMP code which is:

call MPI_Init( ierr )
call MPI_Comm_rank( MPI_COMM_WORLD, rank, ierr )
call MPI_Comm_size( MPI_COMM_WORLD, size, ierr )

t1 = MPI_Wtime( )

!$omp parallel do private(i, x) reduction(+ : pi_partial)
do i = rank, N-1, size
x = (dble( i ) + 0.5_DP) * dx
pi_partial = pi_partial + f( x )
end do

pi_partial = pi_partial * dx
call MPI_Reduce( pi_partial, pi_estimate, 1, MPI_DOUBLE, MPI_SUM, 0, &
MPI_COMM_WORLD, ierr )

Test and Emulate Screens Just Turn Black

I'm making a game (it was in capx form), and when i try to test or emulate it, the screen just turns black. I tried it on all the devices, but it just did the same thing. While making my last game, i was able to use the emulate with no problems, but it doesn't work now. Does anyone know how to fix this? Thank you!

"code modernization"

It was said verbally that Intel would launch the "code modernization" project today.  Maybe this is the reason for the retitling of this forum (which has not been moderated for years).  Of course, "code modernization" means taking advantage of the multiple levels of parallelism supported on Intel platforms, not always what those words might appear to mean.  Initial instructional material (excellent) centers on current Intel(r) Xeon Phi(tm) Knight's Corner, although one would think by the title this isn't just another MIC forum.
