Two or more ports of a same type are identified in a computer. A separate device driver process is initiated for each of the identified ports. A one-to-one correspondence between each of the ports and each of the device driver processes is established.

Executing a kernel device driver as a user space process

Described herein are systems and methods to prevent a controller in a DDIO (data direct input output) system from shifting currently-required data out of a cache memory. In one embodiment, a compute element disables caching of some specific addresses in a non-cache memory, but still enables caching of other addresses in the non-cache memory, thereby practically disabling the DDIO system, so that data sets not currently needed are placed in the addresses in the non-cache memory which are not cached. As a result, currently-required data are not shifted out of cache memory. The compute element then determines that the data sets, which formerly avoided being cached, are now required. The system therefore copies the data sets that are now required from addresses in non-cache memory not accessible to cache memory, to addresses in non-cache memory accessible to cache memory, thereby allowing the caching and processing of such data sets.

Utilizing a cache mechanism by copying a data set from a cache-disabled memory location to a cache-enabled memory location

A method, including receiving, by a user space driver framework (UDF) library executing from a user space of a memory over a monolithic operating system kernel, a kernel application programming interface (API) call from a device driver executing from the user space. The UDF library then performs an operation corresponding to the kernel API call.

A method includes tagging, by a processor executing a first operating system kernel, a region of a memory used by a first storage area network (SAN) adapter driver coupled to a SAN adapter, and decoupling the first SAN adapter driver from the SAN adapter. A boot of a second operating system kernel is then initiated while preserving in the tagged region of the memory contents stored therein. After the boot, a second SAN adapter driver is then coupled to the SAN adapter.

Port throttling across an operating system restart during a hot upgrade

A method for compressing information by a computerized system, the method may include receiving a mixture of DNA data and additional information; and compressing the DNA data to provide compressed DNA data, wherein the compressing comprises encoding the DNA data by using a predefined codeword dictionary that was constructed based upon reference DNA data.

System, method and non-transitory computer readable medium for compressing genetic information

A method includes tagging, by a processor executing a first operating system kernel, a region of a volatile memory used by a first storage area network (SAN) adapter driver coupled to a SAN adapter, and decoupling the first SAN adapter driver from the SAN adapter. A boot of a second operating system kernel is then initiated while preserving in the tagged region of the volatile memory contents stored therein. After the boot, a second SAN adapter driver is then coupled to the SAN adapter.

A method includes tagging, by a processor executing a first operating system kernel, a region of a volatile memory coupled to the processor, and initiating a boot of a second operating system kernel while preserving in the volatile memory contents stored therein. Following the boot of the second operating system kernel, a set of parameters referencing the tagged region is retrieved from the volatile memory, and the tagged region is then used, based on the retrieved set of parameters.

Memory tagging and preservation during a hot upgrade

A processor, executing a first operating system kernel, tags a region of volatile memory coupled to the processor, and initiates a boot of a second operating system kernel while preserving in the volatile memory contents stored therein. Following the boot of the second operating system kernel, a set of parameters referencing the tagged region is retrieved from the volatile memory, and the tagged region is then used, based on the retrieved set of parameters.

A processor, executing a first operating system kernel, tags a region of volatile memory used by a first storage area network (SAN) adapter driver coupled to a SAN adapter, and decouples the first SAN adapter driver from the SAN adapter. A boot of a second operating system kernel is then initiated while preserving in the tagged region of the volatile memory contents stored therein. After the boot, a second SAN adapter driver is then coupled to the SAN adapter.
