The invention comprises (i) a compilation method for automatically converting a single-threaded software program into an application-specific supercomputer, and (ii) the supercomputer system structure generated as a result of applying this method. The compilation method comprises: (a) Converting an arbitrary code fragment from the application into customized hardware whose execution is functionally equivalent to the software execution of the code fragment; and (b) Generating interfaces on the hardware and software parts of the application, which (i) Perform a software-to-hardware program state transfer at the entries of the code fragment; (ii) Perform a hardware-to-software program state transfer at the exits of the code fragment; and (iii) Maintain memory coherence between the software and hardware memories. If the resulting hardware design is large, it is divided into partitions such that each partition can fit into a single chip. Then, a single union chip is created which can realize any of the partitions.

A native binding technique is provided for inserting calls to native functions during translation of subject code to target code, such that function calls in the subject program to subject code functions are replaced in target code with calls to native equivalents of the same functions. Parameters of native function calls are transformed from target code representations to be consistent with native code representations, native code calling conventions, and native function prototypes.

Client software is modified by a translator to use unique variant of linguistic interface of a service. An interceptor pre-processes subsequent client service requests from translated unique linguistic interface to standard linguistic interface implemented by service. Usage of linguistic interfaces of service is contained, rendering service incapable of executing arbitrary input, even if such input is crafted specifically for the service interface.

A method for diagnosing problems in a computer system by providing a user interface for visualizing flows through subsystems of the computer system, and allowing a user to explore relationships between a triage map which graphically depicts subsystems, and a transaction trace graph, which depicts a time sequence of invoked components of the subsystems. In one aspect, in response to a user selecting a portion of the transaction trace graph which depicts an invoked component, the user interface visually distinguishes one of the subsystems which invokes the invoked component. In another aspect, the transaction trace can be played back so that subsystems in the triage map are highlighted in turn, in a time sequence, as components of different subsystems are invoked. A time marker can skip to selected time points which result in updating of the triage map.
