Thanks for your fix. I implemented your fix to create the CUDA context before the arrays are allocated. I also added some coding to print the total available free memory before arrays are allocated. The initial total available free memory is dramatically reduced as I increase the number of MPI...
This convention is not shared with other languages, so it is useful only for communicating between FORTRAN programs.FORM=fm The FORM=fm clause is optional. fm is a character expression. Possible values are 'FORMATTED', 'UNFORMATTED', or 'PRINT'. @ The default is 'FORMATTED'....
Multiprocessing (MP) is the hardware technology on the SPARC platform that supports tightly coupled multi-CPU systems with shared memory. Multiple CPUs provide more power to drive application performance. Multithreading (MT) is the software technology that enables the development of parallel applications,...

My previous CUDA Fortran post covered the mechanics of using shared memory, including static and dynamic allocation. In this post I will show some of the…

CUDA Fortran Programming Guide Version 21.1 | 5 Programming Guide Threads in the same thread block may cooperate by using shared memory, and by synchronizing at a barrier using the SYNCTHREADS() intrinsic. Each thread in the block waits at the call to SYNCTHREADS() until all threads ...

Explicit parallelization of a program requires prior analysis and deep understanding of the application code as well as the concepts of shared-memory parallelization.DO loops are marked for parallelization by directives placed immediately before them. Compile with -xopenmp to enable recognition of OpenMP...
During execution, one map at a time is associated with a shared storage location. When you reference a field in a map, the fields in any previous map become undefined and are succeeded by the fields in the map of the newly referenced field. The amount of memory used by a union is ...
