20090070618 | SYSTEM AND METHOD FOR CALIBRATING A TOD CLOCK - A system, method and computer program product for calibrating a Time Of Day (TOD)-clock in a computing system node provided in a multi-node network. The network comprises an infrastructure of computing devices each having a physical clock providing a time base for executing operations that is stepped to a common oscillator. The system implements steps for obtaining samples of timing values of a computing device in the network, the values including a physical clock value maintained at that device and a TOD-offset value; computing an oscillator skew value from the samples; setting a fine steering rate value as equal to the opposite of the computed oscillator skew value; and, utilizing the fine steering rate value to adjust the physical clock value and correct for potential oscillator skew errors occurring in the oscillator crystal at the computing device. | 03-12-2009 |

20090113085 | FLUSHING WRITE BUFFERS - A first node to cause flushing data units stored in a write buffer of a second node to a memory of the second node. While using a pin-based approach, the central processing unit (CPU) of the first node may activate a first pin coupled to a second pin of the second node that may cause a sequence of operations to flush the write buffer. While using a control-register based approach, the CPU or the memory controller hub (MCH) may configure the control register using an inter-node path such as the SMBus or a data transfer path that may cause a sequence of operations to flush the write buffer. While using an in-band flush mechanism, the CPU may send a message over the data transfer path after transferring the data units that may cause a sequence of operations to flush the write buffer. | 04-30-2009 |
