When you profile your software with VTune™ Amplifier XE you often start from looking at the top function hotspots list. This allows you to see what functions are spending CPU resources, so you can focus your optimization efforts.
Function call counts can provide some additional information to . . .

Combiner/Aggregator synchronization primitive provides mutual exclusion like a mutex, but can be significantly faster in some situations due to better cache performance.

It is known that the Windows Store apps API is missing some commonly used thread functions, such as function CreateThread() and those that work with TLS keys. This is yet another great opportunity to move your application development from thread-based parallelism to task-based parallelism. This ...

If you’ve ever heard about parallel programming it probably sounded like a painful endeavor. Those who have experience with it know that it’s mostly true with “traditional” approaches which incorporate parallel constructs into main-stream programming languages like C++ or FORTRAN. In the light of ...

Hello Forum members,
I run identical multi threaded (openMP) fortran programs on an 'old' windows machine using the Visual Fortran Compiler XE 12.1.0.233 [Intel(R) 64] run on Windows 7 and a 'new' red hat linux server using Fortran Composer_xe_2013.1.117 (run on Red Hat Server 6.3).
When I run my ...

Howdy,
I have two simple questions.
First, are Fortran arrays used in the OpenMP REDUCTION clause considered PRIVATE or FIRSTPRIVATE? In other words, are they assumed to be initialized or uninitialized?
Secondly, is it possible to perform a reduction on only part of an array? Sometimes it is ...

Hello,
I read a report. The authors parallized a memory intensive application with multithreading (by pthreads). They tested the performance on a compute node of two 6-core Xeon X5650. They found the performance will increase with the number for threads, even if the number of theads(e.g., up to ...

With the number of cores increasing on the various OS platforms, in order to maximize efficiency when there are multiple jobs running on the same physical machine, I believe it would be in Intels best interest to support the rankfile syntax used by OpenMPI. This allows upstream schedulers to ...
