An embodiment of the invention is a time-delay invariant predistortion approach to linearize power amplifiers in wireless RF transmitters. The predistortion architecture is based on the stored-compensation or memory-compensation principle by using a combined time-delay addressing method, and therefore, the architecture has an intrinsic, self-calibrating time-delay compensation function. The predistortion architecture only uses a lookup table to conduct both the correction of non-linear responses of a power amplifier and the compensation of any time-delay effects presented in the same system. Due to the time-delay invariant characteristic, the predistortion design has a wider dynamic range processing advantage for wireless RF signals, and therefore can be implemented in multi-carrier and multi-channel wireless systems.

Specifically, pre-marshalling messages allows for client and network devices to create messages in response to a defined first condition. Pre-marshalling messages allows a trading system to do more processing up front before the message is needed and when a second condition is satisfied. Thus, when the message is needed no further or very little processing must be performed to generate and send the message. The client and/or network device may allocate a separate, unused, or under-utilized processing thread to the task of creating pre-marshalled messages. Pre-marshalled messages may be stored in memory at the network device until it is determined that the second condition has been satisfied. Once a pre-marshalled message is sent, the unused pre-marshalled messages that were stored in memory may be deleted or may be overwritten with newly pre-marshalled messages.

A computing device requests access to an application object from a remote storage system in order to locally execute application functionality without hosting application resources. An accessed object is associated with an intent in the storage system and locked. Locking an object in combination with an intent prevents computing devices that are not performing the intent from accessing the object. An intent defines one or more operations to be performed with the requested object, which are serialized as intent steps and stored in the storage system. Upon executing an intent step, the computing device stores a log entry at the storage system signifying the step's completion. A locked object remains locked until the log entries indicate every intent step as complete. Different computing devices can unlock a locked object by executing any incomplete steps of an intent associated with the locked object.

A system determines whether each of multiple data sources stores a corresponding copy of a backup file associated with a data object, in response to receiving a request to recover the backup file associated with the data object. The system allocates multiple portions of the backup file to corresponding multiple data streams, if each of the multiple data sources stores the corresponding copy of the backup file associated with the data object. The system recovers the backup file by concurrently recovering the multiple data streams from the corresponding multiple data sources.

A system and method of performing backups of a system having persistent and non-persistent virtual desktop infrastructure components, database storage components, and file management components. The method first backs up the file management components, then a database server of the database storage components, and then the virtual desktop infrastructure components in an order of a virtual center server, connection server, and then a composer server. If the virtual desktop environment is non-persistent, the system backs up a master image that is used to create non-persistent desktops, and if the virtual desktop environment is persistent, the system backs up the master image that is used to create non-persistent desktops and virtual storage objects that maintain persistence of an identity of the virtual desktop environment.

Techniques are described for memory writes and reads according to a chip-kill scheme that allows recovery of multiple failed wordlines. In an example, when reading data from a superblock of the memory, where the decoding of multiple wordlines failed, a computer system schedules the decoding of failed wordlines based on quantity of bit errors and updates soft information based on convergence or divergence of the scheduled decoding. Such a computer system significantly reduces decoding failures associated with data reads from the memory and allows improved data retention in the memory.

A controller may detect unreliable bits of data, memory cells, or bit lines during an error correction process of a read operation based on an error correction code used to generate parity bits for the data. In some embodiments, the controller may use the error correction code to determine a distribution of unsatisfied checks. Based on the distribution, the controller may detect group(s) of bits that more closely resemble a defective group of bits rather than a non-defective group of bits. Based on the detection, the controller may set reliability metrics to values that indicate low levels or reliability, which in turn may increase the probability of successfully correcting the errors and reduce the amount of work the controller needs to do in order to complete the error correction process.

Techniques are presented for efficiently storing deep neural network (DNN) weights or similar type data sets in non-volatile memory. For data sets, such as DNN weights, where the elements are multi-bit values, bits of the same level of significance from the elements of the data set are formed into data streams. For example, the most significant bit from each of the data elements are formed into one data stream, the next most significant bit into a second data stream, and so on. The different bit streams are then encoded with differing strengths of error correction code (ECC), with streams corresponding to more significant bits encoded with stronger ECC code than streams corresponding to less significant bits, giving the more significant bits of the data set elements a higher level of protection.

Provided are a computer program product, system, and method for managing I/O requests to a storage array of storage devices in a machine having a processor node and device adaptor.

In response to determining that the remaining fault tolerance is a zero fault tolerance that does not permit at least one storage device to fail and allow recovery of data, the device adaptor sends a message to the processor node to cause the processor node to initiate an emergency protocol to terminate a mission critical operation when the processor node is performing the mission critical operation.
