20090113178 | Microprocessor based on event-processing instruction set and event-processing method using the same - Provided are a microprocessor based on event-processing instruction set and an event-processing method using the same. The microprocessor includes an event register controlling an event according to an event-processing instruction set provided in an instruction set architecture (ISA) and an event controller transmitting externally generated events into the microprocessor. Therefore, the microprocessor may be useful to reduce its unnecessary power consumption by suspending the execution of its program when an instruction decoded to execute the program is an event-processing instruction, and also to cut off its unnecessary power consumption that is caused for an interrupt delay period since the program of the microprocessor may be executed again by immediately re-running the microprocessor with the operation of the event register and the event controller when external events are generated. | 04-30-2009 |
20090150706 | WRAPPER CIRCUIT FOR GLOBALLY ASYNCHRONOUS LOCALLY SYNCHRONOUS SYSTEM AND METHOD FOR OPERATING THE SAME - Provided are a high-performance wrapper circuit for a globally asynchronous locally synchronous (GALS) system and a synchronization method using the same, which are capable of solving a synchronization problem caused when data are transmitted between locally synchronous modules employing different clocks, and a method for operating the wrapper circuit. The GALS system includes a clock generator for supplying an operation clock to a locally synchronous module, a sender port for transmitting data to the outside according to a data transmission request signal output from the locally synchronous module, and generating a first clock stop signal for stopping an operation of the clock generator, and a receiver port for receiving data from the outside, and generating a second clock stop signal for stopping the operation of the clock generator. The sender port generates the first clock stop signal to the clock generator when a next data transmission request signal is received before completing a data transmission performed by a previous data transmission request signal output from the locally synchronous module. | 06-11-2009 |
20090151910 | COMBINATION RACK SYSTEM FOR DISCHARGING HOT AIR SEPARATELY, AND SYSTEM AND METHOD FOR COOLING DATA CENTER USING THE COMBINATION RACK SYSTEM - Provided are a combination rack system for discharging hot air separately, and system and method for cooling a data center. The cooling system includes a combination rack system, a discharge pipe connected to the combination rack system, a docking part for connecting the combination rack system and the discharge pipe, a discharge fan for discharging air from the combination rack system to the discharge pipe, an inlet at one side of the discharge pipe for introducing outside air into the discharge pipe, and an outlet at the other side of the discharge pipe for discharging air from the discharge pipe. The combination rack system includes racks and cooling fans. The racks are spaced with their rear sides facing each other, and the cooling fans are disposed between the racks. Therefore, air heated in the combination rack system can be discharged from the combination rack system separately from inner cold air. | 06-18-2009 |
20090157896 | TCP OFFLOAD ENGINE APPARATUS AND METHOD FOR SYSTEM CALL PROCESSING FOR STATIC FILE TRANSMISSION - Provided are a TCP offload engine (TOE) apparatus and method for static file transmission. An apparatus for system call processing for static file transmission includes an application program block for generating a file transmission command upon a user's file transmission request, a BSD socket module for converting the file transmission command of a file unit into a division transmission command for division-transmission of a certain size unit, a TOE kernel module for receiving the division transmission command and converting the division transmission command into a TOE control command, and a TOE apparatus module for generating a data packet of the certain size for network transmission in response to the TOE control command and transmitting the data packet to a node having requested file transmission. | 06-18-2009 |
20090158048 | METHOD, CLIENT AND SYSTEM FOR REVERSED ACCESS TO MANAGEMENT SERVER USING ONE-TIME PASSWORD - Provided are a method, client and system for reservation access to a management server using a one-time password. A generated personal identification number (PIN) is transmitted to the management server when a reservation time comes. The management server generates a random number encrypted using the PIN and transmits the random number to the client. The random number encrypted using the PIN is received, the received random number is encrypted by a symmetric-key algorithm using a client secret key and is transmitted to the management server. The management server receives the random number encrypted using the client secret key, and decrypts the received random number using a server secret key and the PIN. A random number before the encryption using the PIN is compared with a decrypted random number, and access of the client is accepted if the two numbers are identical. Automatic access to a system employing a one-time password authentication method can be made through an arbitrary route according to previously reserved settings to perform information collection and to process specific functions in the case where a system manager is unable to directly access the system through a determined route because of temporal and spatial limitations. | 06-18-2009 |
20090158074 | CLUSTER SYSTEM WITH REDUCED POWER CONSUMPTION AND POWER MANAGEMENT METHOD THEREOF - Provided are a cluster system, which can reduce power consumption by controlling power at a cluster level according to loads, and a power management method of the cluster system. The cluster system includes a plurality of management target nodes for performing an actual task which the cluster system is supposed to perform, a load balancer/switch for distributing a user's request received through an external network into the management target nodes, and a power management master for monitoring a load of an entire system and performing a power management by controlling the load balancer/switch. The power management master classifies the management target nodes into a power on group and a power off group. | 06-18-2009 |
20110006607 | HYBRID POWER SUPPLY APPARATUS FOR DATA CENTER - A hybrid power supply apparatus for data center includes: one or more power sources; and an uninterruptible rack level power supply unit supplied with an Alternating Current (AC) power from said one or more power sources, and configured to supply Direct Current (DC) power to a rack, the power supply unit supplying the DC power to the rack without interruption when supply of the power from said one or more power sources is stopped. The apparatus further includes a node provided in the rack and supplied with the DC power from the uninterruptible rack level power supply unit. | 01-13-2011 |
20110019352 | RACK-MOUNT COMPUTER - A rack-mount computer mounted in a rack system connected to multiple terminals, includes: a power distribution board (PDB) for supplying each power load with DC power; a storage device connected to a backplane for receiving power from the PDB in a hotplug manner; a mainboard for receiving power from the PDB to execute computing; and an input/output card, connected to the mainboard, for processing specific input/output data. | 01-27-2011 |
20110119514 | POWER CONTROL APPARATUS AND METHOD FOR CLUSTER SYSTEM - A power control apparatus for a cluster system, includes a cluster including a plurality of nodes, each equipped with a battery; and a power control unit connected to the cluster over a network and configured to monitor power management information and performance information of the cluster and to set a power capping threshold based on the monitored power management information and performance information of the cluster.
