A computer-implemented process, system and program product for remote array processing receives a requested array in a remote execution container, generates a fingerprint of the requested array, bundles the fingerprint with the requested array and returns a pointer to array elements of the requested array to a caller. The computer-implemented process further receives a call to release the requested array from the caller to form a received release, determines, using the fingerprint, whether the… Show more

A computer-implemented process, system and program product for remote array processing receives a requested array in a remote execution container, generates a fingerprint of the requested array, bundles the fingerprint with the requested array and returns a pointer to array elements of the requested array to a caller. The computer-implemented process further receives a call to release the requested array from the caller to form a received release, determines, using the fingerprint, whether the requested array has been modified and responsive to a determination that the array has been modified, sending a call to release the requested array to a virtual machine and responsive to a determination that the array has not been modified, not sending a call to release the requested array to a virtual machine.

An illustrative embodiment provides a computer-implemented process for distributed management of native interface arrays. The computer-implemented process obtains an array type native interface call in a first system from a caller in a second system, identifies an array type of the array type native interface call to form an identified array type, and requests array elements associated with the identified array type to form requested array elements, wherein added metadata is associated with the… Show more

An illustrative embodiment provides a computer-implemented process for distributed management of native interface arrays. The computer-implemented process obtains an array type native interface call in a first system from a caller in a second system, identifies an array type of the array type native interface call to form an identified array type, and requests array elements associated with the identified array type to form requested array elements, wherein added metadata is associated with the requested array elements. The computer-implemented process builds an enhanced data structure using the requested array elements and the associated added metadata and returns a pointer within the enhanced data structure to the caller. The pointer can be used by the caller to manipulate array data of the array elements, and the first system can calculate an address of the added metadata in constant time from the pointer. Show less

An initial request for a reference to a data container is sent from a distributed enhanced remote execution container native interface component of a distributed virtual machine to a distributed enhanced virtual machine native interface component of the distributed virtual machine in response to receipt of the initial request from a remote execution container. A data mirror data structure including immutable data and the reference to the data container is received. The received data mirror data… Show more

An initial request for a reference to a data container is sent from a distributed enhanced remote execution container native interface component of a distributed virtual machine to a distributed enhanced virtual machine native interface component of the distributed virtual machine in response to receipt of the initial request from a remote execution container. A data mirror data structure including immutable data and the reference to the data container is received. The received data mirror data structure including the immutable data and the reference to the data container is stored within a local memory storage area. A reference to the locally-stored data mirror data structure is returned to the remote execution container in response to the initial request for the reference to the data container. Show less

A method for running multiple copies of the same native code in a Java Virtual Machine is described. In one embodiment, such a method includes providing a class to enable segregating multiple copies of the same native code. The method defines, within the class, a native method configured to dispatch operation of the native code. The method further includes generating first and second instances of the class. Calling the native method in the first instance causes a first copy of the native code… Show more

A method for running multiple copies of the same native code in a Java Virtual Machine is described. In one embodiment, such a method includes providing a class to enable segregating multiple copies of the same native code. The method defines, within the class, a native method configured to dispatch operation of the native code. The method further includes generating first and second instances of the class. Calling the native method in the first instance causes a first copy of the native code to run in a first remote execution container (e.g., a first process). Similarly, calling the native method in the second instance causes a second copy of the native code to run in a second remote execution container (e.g., a second process) separate from the first remote execution container. A corresponding computer program product is also disclosed. Show less
