(You must be using Data Explorer SMP to take advantage of this feature.) Its output is a composite field, which is treated as a single entity by other modules. #!N #!I0 #!N #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* input #!EF #!EF #!I50 #!N is the input object to be partitioned. If this parameter specifies a group, each group member is partitioned with the same #!F-adobe-times-bold-r-normal--18* n #!EF and #!F-adobe-times-bold-r-normal--18* size #!EF parameters. #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* n #!EF #!EF #!I50 #!N is the approximate number of partitions to be created. However, the module will not create partitions smaller than #!F-adobe-times-bold-r-normal--18* size #!EF (see below). #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* size #!EF #!EF #!I50 #!N is the minimum number of connection elements per partition. #!N #!N If #!F-adobe-times-bold-r-normal--18* n #!EF * #!F-adobe-times-bold-r-normal--18* size #!EF is larger than the total number of points, the output number of partitions may be smaller than #!F-adobe-times-bold-r-normal--18* n #!EF #!N #!N If you do not specify #!F-adobe-times-bold-r-normal--18* n #!EF or #!F-adobe-times-bold-r-normal--18* size #!EF , appropriate default values are supplied, depending on the number of processors available. #!I0 #!N #!N Note: On a uniprocessor machine, n = 1 by default. Consequently, the same programs can be run on uniprocessor and multiprocessor machines without modification. #!N #!N Components #!N #!N All components in the input are propagated to the output. #!N #!N Example Visual Programs #!N #!N #!CForestGreen #!N #!N #!F-adobe-courier-bold-r-normal--18* #!N ExampleSMP.net #!EF #!N #!N #!EC #!N #!N See Also #!N #!N #!Limport,dxall871 h Import #!EL #!N #!N #!N #!F-adobe-times-medium-i-normal--18* Next Topic #!EF #!N #!N #!Lpick,dxall903 h Pick #!EL #!N #!F-adobe-times-medium-i-normal--18* #!N
