Abstract: Embodiments include method, systems and computer program products for resource management of untrusted programs. In some embodiments, a first request to process an asynchronous event by an untrusted application may be received. The first request may include a host memory address. A counter may be incremented in response to receiving the first request. A device memory address may be retrieved from a device translation table using the host memory address. Processing the first request by a device using the device memory address may be facilitated. A second request to unregister the host memory address may be received. The counter may be determined to be non-zero. An action may be implemented in response to determining that the counter is non-zero.

Abstract: A computer-implemented method includes writing, by a producer, data to one or more buffers. The one or more buffers include a plurality of cells and together form a circular buffer, and an input cursor indicates which cell of the plurality of cells the producer writes to. The method further includes reading, by a consumer, data from the one or more buffers, where an output cursor indicates which cell of the plurality of cells the consumer reads from. It is detected that the consumer is overrun by the producer. A throughput of the consumer is compared to a throughput of the producer, responsive to detecting that the consumer is overrun by the producer. The output cursor is synchronized to a new position, by a computer processor, where the new position is selected based on comparing the throughput of the consumer to the throughput of the producer.

Abstract: A computer-implemented test method which includes obtaining, using a processor system, key words relating to a first application program interface developed utilizing a first programming language and constructing, using a processor system, a testing protocol utilizing the keywords. The testing protocol is applied to the first application program interface to create a first application program interface testing result. The testing protocol is also applied to a second application program interface developed utilizing a second programming language to create a second application program interface testing result. The first application program interface testing results are compared with the second application program interface testing results to determine if the second application program interface provided an accurate output.
