Abstract: The apparatus and method described herein are for handling shared memory accesses between multiple processors utilizing lock-free synchronization through transactional-execution. A transaction demarcated in software is speculatively executed. During execution invalidating remote accesses/requests to addresses loaded from and to be written to shared memory are tracked by a transaction buffer. If an invalidating access is encountered, the transaction is re-executed. After a pre-determined number of times re-executing the transaction, the transaction may be re-executed non-speculatively with locks/semaphores.

Abstract: In one embodiment of the present invention, a method includes verifying a master processor of a system; validating a trusted agent with the master processor if the master processor is verified; and launching the trusted agent on a plurality of processors of the system if the trusted agent is validated. After execution of such a trusted agent, a secure kernel may then be launched, in certain embodiments. The system may be a multiprocessor server system having a partially or fully connected topology with arbitrary point-to-point interconnects, for example.

Abstract: Systems, apparatus, and computer-implemented methods are provided for the hybridization of cache memory utilizing both magnetic and solid-state memory media. A solid-state cache controller apparatus can be coupled to a host computing system to maximize efficiency of the system in a manner that is transparent to the high-level applications using the system. The apparatus includes an associative memory component and a solid-state cache control component. Solid-state memory is configured to store data blocks of host read operations. If a host-read operation is requested, the controller communicates with a solid-state cache memory controller to determine whether a tag array data structure indicates a cached copy of the requested data block is available in solid-state memory.
