Abstract: The disclosed embodiments relate to a system that removes quantization effects from a set of time-series signals to produce highly accurate approximations of a set of original unquantized signals. During operation, for each time-series signal in the set of time-series signals, the system determines a number of quantization levels (NQL) in the time-series signal. Next, the system performs a fast Fourier transform (FFT) on the time-series signal to produce a set of Fourier modes for the time-series signal. The system then determines an optimal number of Fourier modes (Nmode) to reconstruct the time-series signal based on the determined NQL for the time-series signal. Next, the system selects Nmode largest-amplitude Fourier modes from the set of Fourier modes for the time-series signal. The system then performs an inverse FFT operation using the Nmode largest-amplitude Fourier modes to produce a dequantized time-series signal to be used in place of the time-series signal.

Abstract: A technique is described for managing processor (CPU) resources in a host having virtual machines (VMs) executed thereon. A target size of a VM is determined based on its demand and CPU entitlement. If the VM's current size exceeds the target size, the technique dynamically changes the size of a VM in the host by increasing or decreasing the number of virtual CPUs available to the VM. To “deactivate” virtual CPUs, a high-priority balloon thread is launched and pinned to one of the virtual CPUs targeted for deactivation, and the underlying hypervisor deschedules execution of the virtual CPU accordingly. To “activate” virtual CPUs, the number of virtual CPUs, the launched balloon thread may be killed.

A scheduler is employed to balance a load imposed by virtual machines, each having a plurality of virtual processors, across various logical processors (comprising a physical machine) that are running threads in parallel. The threads are issued by the virtual processors and often cause spin waits that inefficiently consume capacity of the logical processors that are executing the threads. Upon detecting a spin-wait state of the logical processor(s), the scheduler will opportunistically grant time-slice extensions to virtual processors that are running a critical section of code, thus, mitigating performance loss on the front end.

Abstract: Techniques for handling memory errors are disclosed. Various memory units of an accelerated processing device (“APD”) include error units for detecting errors in data stored in the memory (e.g., using parity protection or error correcting code). Upon detecting an error considered to be an “initial uncorrectable error,” the error unit triggers transmission of an initial uncorrectable error interrupt (“IUE interrupt”) to a processor. This IUE interrupt includes information identifying the specific memory unit in which the error occurred (and possible other information about the error). A halt interrupt is generated and transmitted to the processor in response to the data having the error being consumed (i.e., used by an operation such as an instruction or command), which causes the APD to halt operations. If the data having the error is not consumed, then the halt interrupt is never generated (that the error occurred may remain logged, however).

Related systems and computer program products are also discussed.

Based on the deviation, the component is determined to have failed. Based in part on the failed component, the categories, and the weights, a health index is determined in real-time. The health index indicates in part how much the component having failed affects a measure of health of the HA system.

Abstract: A computer system having reduced write latency and methods for use in computer systems for reducing write latency are provided. Processing circuitry of the computer system is configured to execute a volume filter driver (VFD) that can be switched between a fast termination (FT) mode of operations and a normal, or quiescent, mode of operations. When the processing circuitry receives input/output (IO) write requests to write data to memory while the VFD is in the FT mode of operations, the VFD causes metadata associated with received IO write requests to be written to a volume of memory while preventing actual data associated with received IO write requests from being written to the volume, thereby resulting in extremely fast FT mode operation. After the file has been written to the volume, the VFD enters the quiescent mode of operations during which the VFD passes all IO write requests to the volume.

Abstract: A control method implemented using a server and a server control device. When a server starts abnormally due to an exception of a master central processing unit (CPU), a platform controller hub (PCH) connected to the master CPU, or a Flash that is connected to the PCH connected to the master CPU, the master CPU is reconfigured. It is implemented that, when a startup exception occurs on a server that supports hard partitioning, it can be still ensured that the server normally starts and runs, thereby improving reliability and stability of the server. Therefore, Reliability, Availability and Serviceability (RAS) of the entire server is improved. In addition, a problem that a system fails to run due to an exception of a Flash is solved, and an original dual Basic Input/Output Systems (BIOS) design manner may no longer be used, thereby reducing Flash chip costs of the server.

Abstract: A method, system, and apparatus are provided for retiring computer memory blocks. Two overall schemes are provided for separating poorly functioning blocks from normally functioning blocks. In a first scheme, after data relocation is finished, firmware remembers the old physical memory block. As soon as the system writes to the old physical memory block with new data, firmware issues a read again and receives back a count of error bits. If the returned error bits are still high, then the system identifies the block as being weak and retires the block. In a second scheme, firmware tracks statistics for data relocates, block reads, activity timers, among other statistics. If some blocks have abnormal activities (e.g., too many data relocates, too many reads, etc.), then the system may identify the block as being weak and may retire the physical memory block.

Abstract: A dual-mode debugger can debug native code or interpreted code. Transitioning between modes can be triggered by defined bailout conditions. A program can be debugged by attaching a debugger and compiling the program into native code under the debugger. At defined points in the program, debugging can transition from native mode to interpreted mode. Debugging the native code can stop, current state can be captured, and an interpreter can be instantiated. An interpreter stack can be created and can be populated with the captured current state. Debugging operations which involve execution control: pausing execution, continuing execution, stepping into, out of or over a section of code and so on, can occur in interpreted mode, which is typically easier to implement. Debugging operations which involve inspection and modification of variables can occur in native mode.
