  • Publication number: 20230214480
    Abstract: Protection of a kernel from a sniff and code reuse attack. A kernel mode page table in initialized in a kernel. The kernel page entries in the kernel mode page table are set from s-pages to u-pages. Supervisor mode access prevention is enabled in the u-pages. Code contained in the kernel page entries in the u-pages is executed, the kernel page entries in the u-pages are capable of execution but are not capable of being accessed and read directly.

  • Patent number: 11307889
    Abstract: Techniques for virtual machines include receiving virtual machine (VM) requests, and finding one or more VM requests of the VM requests that optimize available resources of a candidate host machine while seeking to minimize differences between the one or more VM requests and the candidate host machine. The one or more VM requests are allocated to the candidate host machine.

  • Patent number: 9562225
    Abstract: Provided is a gold nanocage with pores, charged ligand molecules covalently bound to internal surfaces of the gold nanocage, and payload molecules electrostatically adsorbed onto said charged ligand molecules, wherein a pore diameter is between 1.2 and 20 times a gyration radius of the payload molecule. Also provided is a method for making a nanoparticle, including using polyvinylpyrrolidone as a capping agent in a galvanic replacement reaction to convert a silver nanocube into a gold nanocage having pores, replacing the polyvinylpyrrolidone on internal surfaces with charged ligand molecules, and electrostatically adsorbing payload molecules onto the charged ligand molecules, with a pore diameter less than twenty times a gyration radius of the payload molecule. Also provided is a method of delivering a pharmacological agent to a mammalian cell, including contacting the cell with a gold nanocage having pores, ligand molecules bound to internal surfaces, and pharmacological agent adsorbed onto ligand molecules.

  • Patent number: 8914799
    Abstract: A method and system for creating and executing tasks within a multithreaded application composed according to the OpenMP application programming interface (API). The method includes generating threads within a parallel region of the application, and setting a counter equal to the quantity of the threads. The method also includes, for each one of the plurality of threads, assigning an implicit task, and executing the implicit task. Further, the method includes, upon encountering a task construct, during execution of the implicit tack, for an explicit asynchronous task generating the explicit asynchronous task, adding the explicit asynchronous task to a first task queue, where the first task queue corresponds to the one of the plurality of threads; and incrementing the counter by one.
