A data visualization arrangement for facilitating the display of data items comprising a selected region of an object in a selected one of a plurality of display modes. The arrangement comprises a data object store, an interface, an object region retrieval component and a display. The data object store stores the data object, the data object comprising a plurality of data items in a predetermined organization. The interface receives a region identification for identifying a particular region of the object and a display mode identification. The object region retrieval component retrieves data items from a region of the data object as identified by the region identification received by the interface. Finally, the display receives the data items as retrieved by the object region retrieval mechanism and displays them in the display mode as identified by the display mode identification.

A data visualization arrangement facilitates the display of a selected region of a multi-dimensional data object in a selected one of a plurality of display modes. The arrangement comprises a data object store, an interface, an object region retrieval component and a display. The data object store stores the data object, the data object comprising a plurality of data items in a predetermined organization. The interface receives a region identification for identifying a particular region of the object and a display mode identification. The object region retrieval component retrieves data items from a region of the data object as identified by the region identification received by the interface. Finally, the display receives the data items as retrieved by the object region retrieval mechanism and displays them in the display mode as identified by the display mode identification.

A debugger for use in connection with a parallel computer including a plurality of processing nodes. The debugger enables the operator to establish a processing node set in response to certain criteria, such as the respective identifications of the processing node and their prior processing under the debugger. The debugger, in response to a processing node set establishment command from the operator, enables each processing node to establish and condition a set membership flag in response to the operator-supplied set membership criteria. The debugger is then responsive to a debugging command from the operator to enable the processing nodes to use their respective set membership flags to condition their execution of the debugging command.

Parallel processing system including arrangement for establishing and

A compiler for compiling a computer program which is adapted for use with a data parallel computer. The compiler supports variables which involve parallelism. Variables which involve parallelism are parallel variables, templates for parallel variables called shapes, and pointers to parallel variables. For each variable involving parallelism declared globally in the source code, the compiler of the present invention emits in the target code a declaration of a global scalar variable. It further emits in the target code a start trap. When executed, the start trap allocates memory and a data structure for the global variables involving parallelism. The start trap also initializes the data structures and global variables involving parallelism. Finally, the compiler of the present invention emits in the target code one or more statements which, at run time, will cause the start trap to be invoked before the execution of any statement in which one of the global variables involving parallelism is read from or written to.

The present invention is directed towards a compiler for processing parallel communication instructions on a data parallel computer. The compiler of the present invention comprises a front end, a middle end, an optimizer, and a back end. The front end constructs a parse tree which includes nodes representative of parallel communication instructions. The middle end generates an intermediate representation (IR) tree from the parse tree. The IR tree includes general parallel communication IR nodes representative of target code to carry out parallel communication with general communication. An efficient parallel communication module of the optimizer replaces general parallel communication IR nodes with grid parallel communication IR nodes where doing so would result in more efficient target code. The grid parallel communication IR nodes represent target code to carry out parallel communication instructions with grid communication. The back end generates target code from the optimized IR tree.
