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 program product for optimizing page table manipulations is provided and includes a computer readable storage medium having program instructions that are readable and executable by a processing circuit to cause the processing circuit to create and maintain a translation table with a translation look-aside buffer (TLB) disposed to cache priority translations, update the translation table upon de-registration of a DMA address, allocate entries in the translation table from low to high memory addresses during memory registration, maintain a cursor for identifying where to search for available entries upon performance of a new registration, advance the cursor from entry-to-entry in the translation table and wrap the cursor from an end of the translation table to a beginning of the translation table and issue a synchronous TLB invalidation instruction to invalidate the TLB upon at least one wrapping and an entry being identified and updated.

Abstract: A computer program product for data compression is provided. The computer program product includes a computer readable storage medium having program instructions embodied therewith. The program instructions are readable and executable by a processing circuit to cause the processing circuit to execute software compression for first requests for data compression that have respective sizes below a predefined threshold, forward second requests for data compression having respective sizes above the predefined threshold to a hardware accelerator and maintain a persistence of a compression dictionary used for executing the second requests across executions of the first and second requests.

Abstract: A system that collects statistics and auditing information may receive a first request from an analytics application to access a first set of data. An application program interface (API) of the system may access the first set of data within an in-memory buffer of the system. The first set of data may be retained within the in-memory buffer as defined by a policy. The policy may include retaining the first set of data within the in-memory buffer even after the first set of data is written to non-volatile storage.

Abstract: A computer-implemented method for monitoring server stability based on a stability time specification of a server includes specifying a stability time for the server, wherein the stability time is defined as a time between a starting state of the server and a stability point of the server. The server activity is monitored by an availability manager to determine an availability status of the server. Responsive to the server activity progressing to the stability point within the stability time, an embodiment determines that the server is stable. Responsive to the server activity failing to progress to the stability point within the stability time, an embodiment determines that the server is unreliable.
