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.

Protection of kernel from code reuse attacks

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.

Schedule virtual machines

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.
