Shared Concepts in High-Performance Computing

specifies the number of bytes per character that is used in processing character strings in multibyte encodings. The default is the bytes per character of the encoding. The number of characters in a string is calculated as the byte length of the string divided by the bytes per character of the encoding. This will be incorrect when the strings in the multibyte encoding contain one or more single byte characters. In such cases, setting BPC=1 enables appropriate byte lengths to be used in processing such strings.

requests a table that shows a timing breakdown of the procedure steps.

specifies the number of threads for analytic computations and overrides the SAS system option THREADS | NOTHREADS. If you do not specify the NTHREADS= option, the number of threads is determined based on the number of CPUs on the host on which the analytic computations execute. The algorithm by which a CPU count is converted to a thread count is specific to the high-performance analytical procedure. Most procedures create one thread per CPU for the analytic computations.

By default, high-performance analytical procedures run in multiple concurrent threads unless multithreading has been turned off by the NOTHREADS system option or you force single-threaded execution by specifying NTHREADS=1. The largest number that can be specified for n is 256. Individual high-performance analytical procedures can impose more stringent limits if called for by algorithmic considerations.
