The following links are provided here in case you need quick access to detailed device API documentation. These are useful (but optional) APIs that you can use to build hybrid mobile HTML5 apps with the Intel XDK.
1. A loop contains a conditional statement
2. The conditional statement is controlling the assignment of a scalar value.
3. The logic of the assignment is such that the value of the scalar at the end of execution of the loop depends on the loop executing iterations strictly in-order AND
4. the scalar value is referenced AFTER the loop exits.
Below is an example:
I want to enable work-stealing in intel OpenMP and thus set the variable KMP_TASKING=1. However, all OpenMP based programs have segmentation fault (core dumped) at the start of the parallel region.
Please, could somebody give me some guidelines in order to enable the work-stealing feature in intel OpenMP? I use the latest icc and ifort to compile the C and fortran programs, respectively.
Thanks a lot for your help.
I am looking for flag option that used to generate intermediate representation of OpenMP* on icc, such as explain in (1.7.1 Work Sharing Example).
Also, is it possible to extend icc compiler by adding new pragma (directive)?
Thanks in adavnce
Is there any way I can summon nCores with OpenMP?
Selective Use of gatherhint/scatterhint Instructions
The -opt-gather-scatter-unroll=<N> compiler option can be used to generate gatherhint/scatterhint instructions supported by the coprocessor. This is useful if your code is doing non-unit stride accesses and/or uses indirect addressing via pointers or index arrays.
