1950 | ||||
1951 | __kmpc_copyprivate implements the interface for the private data broadcast | |||
1952 | needed for the copyprivate clause associated with a single region in an | |||
1953 | OpenMP<sup>*</sup> program (both C and Fortran). | |||
1954 | All threads participating in the parallel region call this routine. | |||
1955 | One of the threads (called the single thread) should have the <tt>didit</tt> | |||
1956 | variable set to 1 and all other threads should have that variable set to 0. | |||
1957 | All threads pass a pointer to a data buffer (cpy_data) that they have built. | |||
1958 | ||||
1959 | The OpenMP specification forbids the use of nowait on the single region when a | |||
1960 | copyprivate clause is present. However, @ref __kmpc_copyprivate implements a | |||
1961 | barrier internally to avoid race conditions, so the code generation for the | |||
1962 | single region should avoid generating a barrier after the call to @ref | |||
1963 | __kmpc_copyprivate. | |||
1964 | ||||
1965 | The <tt>gtid</tt> parameter is the global thread id for the current thread. | |||
1966 | The <tt>loc</tt> parameter is a pointer to source location information. | |||
1967 | ||||
1968 | Internal implementation: The single thread will first copy its descriptor | |||
1969 | address (cpy_data) to a team-private location, then the other threads will each | |||
1970 | call the function pointed to by the parameter cpy_func, which carries out the | |||
1971 | copy by copying the data using the cpy_data buffer. | |||
1972 | ||||
1973 | The cpy_func routine used for the copy and the contents of the data area defined | |||
1974 | by cpy_data and cpy_size may be built in any fashion that will allow the copy | |||
1975 | to be done. For instance, the cpy_data buffer can hold the actual data to be | |||
1976 | copied or it may hold a list of pointers to the data. The cpy_func routine must | |||
1977 | interpret the cpy_data buffer appropriately. | |||
1978 | ||||
1979 | The interface to cpy_func is as follows: | |||
1980 | @code | |||
1981 | void cpy_func( void *destination, void *source ) | |||
1982 | @endcode | |||
1983 | where void *destination is the cpy_data pointer for the thread being copied to | |||
1984 | and void *source is the cpy_data pointer for the thread being copied from. | |||
