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 . . .

(This work was done by Vivek Lingegowda during his internship at Intel.)
When parallel applications have to initialize their data from file as their input or write result data to file as their output, when not optimized, the data read/write can become a limiting factor for the multi-threaded ...

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 ...

Regarding performance, assuming we get a block of data that will be freqenctly accessed by each threads, and these data are read-only, which means threads wont do anything besides reading the data, then is it benefitial to create one copy of these data (assuming the data there read-only, and the ...

Hello,
I measure the performance of memory copy in a NUMA machine with 4 Xeon(R) CPU E5-4620 processors. When I copy data in the local memory, I can get up to almost 10GB/s. However, when I copy data from remote memory, I get much worse performance, only around 1GB/s. I use memcpy() to copy data ...

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 ...
