Publication number: 20150186146Abstract: Systems and methods for predicting execution paths of at least one target program of a plurality of programs that are run in parallel are described. In one method, execution flows of programs are generated. In addition, the programs are executed to obtain debug logs from the programs. Further, communication messages transmitted between the execution flows are identified from the debug logs. A deduction that at least one conditional branch was taken in at least one given execution flow of the first execution flows by the target program is made based on the communication messages. Based on the deduction, at least one conditional branch that was not taken is removed from the given execution flow. In addition, modified execution flows that were modified in accordance with the removal are output to indicate predicted execution paths of the target program.Type: ApplicationFiled: March 10, 2015Publication date: July 2, 2015Inventors: TAKAYUKI KUSHIDA, TAKUYA MISHINA, HITOMI TAKAHASHI, TAKAAKI TATEISHI

Patent number: 8997060Abstract: Systems and methods for predicting execution paths of at least one target program of a plurality of programs that are run in parallel are described. In one method, execution flows of programs are generated by conducting a static analysis. In addition, the programs are executed to obtain debug logs from the programs. Further, communication messages transmitted between the execution flows are identified from the debug logs. A deduction that at least one conditional branch was taken in at least one given execution flow of the first execution flows by the target program is made based on the communication messages that are identified in the debug logs. Based on the deduction, at least one conditional branch that was not taken is removed from the given execution flow. In addition, modified execution flows that were modified in accordance with the removal are output to indicate predicted execution paths of the target program.Type: GrantFiled: July 31, 2013Date of Patent: March 31, 2015Assignee: International Business Machines CorporationInventors: Takayuki Kushida, Takuya Mishina, Hitomi Takahashi, Takaaki Tateishi

Patent number: 8868381Abstract: A method converts a plurality of functional blocks into linear blocks such that the nonlinear blocks are divided into a plurality of states through switched linearization. The plurality of states generated by said switched linearization is then transitioned selectively based on a predetermined operational scenario. Each state is then tested separately to ensure that implementation of the states are safe. A first guard block is provided when a state is deemed unsafe such that the first guard block is enabled to cause a system shutdown so as to prevent further processing that can cause an unsafe result.Type: GrantFiled: December 6, 2010Date of Patent: October 21, 2014Assignee: International Business Machines CorporationInventors: Hideaki Komatsu, Hitomi Takahashi, Gang Zhang

Publication number: 20070186824Abstract: A sidewalk tile with snow-removal function is stably obtained that is capable of being heated to a desired temperature, while at the same time sufficiently maintaining strength. A heat-generating concrete body is obtained by mixing particle-form (granular) or powder-form carbon material with un-hardened concrete at a specified ratio, and then pressing it with a high-pressure press at a pressure of approximately 980 kN to remove moisture and to form it into a tile shape. A pair of electrodes are embedded in end sections on both ends in the width direction of the heat-generating concrete body. The outer surfaces of the heat-generating concrete body are covered with an insulation-coating layer. One side and the circumference of the heat-generating concrete body are covered with un-hardened concrete and formed into a single tile shape by pressing with a high-pressure press to obtain a sidewalk tile with the snow-removal function.Type: ApplicationFiled: December 24, 2004Publication date: August 16, 2007Applicant: HITOMI TAKAHASHIInventors: Hitomi Takahashi, Teitaro Takahashi, Tetsuo Adachi, Hiroshi Kameyama
