OpenMP thread pinning

Hello,

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

A quick peek at hardware-accelerated Android* emulation, using Intel® Hardware Accelerated Execution Manager (Intel® HAXM)

A look at the advantages of using Intel(R) HAXM for Android Emulation. HAXM speeds up Android app emulation on a host development machine and is available as a feature of Intel(R) INDE or as a standalone release.

kmp_reduce non atomic

Hello, 

I have studied the openmp reduction function kmp_reduce and the conclusion is : 

if (lck!=NULL) ==> we can do CRITICAL version
if (reduce_data!=NULL && reduce_func!=NULL) ==> we can do TREE version
if ((loc->flags & KMP_IDENT_ATOMIC_REDUCE) == KMP_IDENT_ATOMIC_REDUCE) ==> we can do ATOMIC version

So i have created 3 flags which tests the conditions above (CRITICAL, TREE, ATOMIC)

I have done some tests of openmp reductions to look at the results of these flags, but it seems to be always at 1.

Intel Graphics Beta Driver for Windows 10

As the Windows 10 launch is a few weeks away many people are interested in Beta graphics drivers for Intel Graphics on Windows 10. In Intel is taking a different approach for Windows 10 and is providing Beta drivers to Microsoft directly. The Intel drivers will be available to via Windows Update.  Many people are accustomed to getting Beta drivers for pre-release Windows directly from Intel, so we’ve taken extra care to make sure the Windows Update process is as seamless and trouble-free as possible.
