threadfence() is one method to enforce a specific order. All global and shared memory accesses made by the calling thread prior to threadfence() are visible to: All threads in the thread block for shared memory accesses All threads in the device for global memory accesses THREADFENCE_BLOCK...
For more information on Fortran directives and C/C++ pragmas, refer to Using OpenMP and Using Directives and Pragmas. 1.4. Filename Conventions The PGI compilers use the filenames that you specify on the command line to find and to create input and output files. This section ...
The RDDs are not cached in memory by default, therefore, when data are reused, a persist method is needed to avoid re-computation. Various cluster management options are available for running Spark. The options range from the simple Spark integrated Stand-alone Scheduler to other widespread ...

1 OpenMP (Open Multi-Processing) is an application programming interface that facilitates the development of parallel applications for shared memory systems. 24 IBM POWER8 High-Performance Computing Guide: IBM Power System S822LC (8335-GTB) Edition For more information about XL Fortran, see the IBM...
OpenMP profiling is not supported for Fortran applications that use both OpenACC and OpenMP, and use critical sections, OpenMP lock API calls, or performs I/O. OpenACC profiling of these applications is still possible by disabling OpenMP profiling with the '--openmp-profiling off' option to pg...
CUDA Fortran can be used in OpenMP programs, and the CUDA Libraries in this document are thread safe with respect to host CPU threads. Further examples are included in chapter Examples. 1.5. Using CUDA Libraries from CUDA Fortran Device Code The cuBLAS and cuRAND libraries have functions ...
The OpenACC Application Program Interface is a collection of compiler directives and runtime routines that allow you, the programmer, to specify loops and regions of code in standard C, C++ and Fortran that you want offloaded from a host CPU to an attached accelerator, such as a GPU. The ...
Fixed-form Fortran OpenMP directives begin with !$OMP, C$OMP, or *$OMP, beginning in column 1. Free-form Fortran OpenMP directives begin with !$OMP. OpenMP pragmas for C++ and C begin with #pragma omp. This format allows the user to have a single source code file for use with or ...
