Hipernetch: High-Performance FPGA Network Switch

We present Hipernetch, a novel FPGA-based design for performing high-bandwidth network switching. FPGAs have recently become more popular in data centers due to their promising capabilities for a wide range of applications. With the recent surge in transceiver bandwidth, they could further benefit the implementation and refinement of network switches used in data centers. Hipernetch replaces the crossbar with a “combined parallel round-robin arbiter”. Unlike a crossbar, the combined parallel round-robin arbiter is easy to pipeline, and does not require centralised iterative scheduling algorithms that try to fit too many steps in a single or a few FPGA cycles. The result is a network switch implementation on FPGAs operating at a high frequency and with a low port-to-port latency. Our proposed Hipernetch architecture additionally provides a competitive switching performance approaching output-queued crossbar switches. Our implemented Hipernetch designs exhibit a throughput that exceeds 100 Gbps per port for switches of up to 16 ports, reaching an aggregate throughput of around 1.7 Tbps.

The Impact of Drill and Strokes Training Methods on the Accuracy of Smash Direction in Badmiton

Penelitian ini dilatar belakangi oleh observasi yang dilakukan oleh peneliti pada kejuaraan POMRAYON Solo Raya mengenai ketepatan arah smash yang dilakukan para atlet UKM bulutangkis Universitas Muhammadiyah Surakarta yang masih seringkali melakukan kesalahan dan kurang dalam penerapannya. Penelitiaan ini bertujuan untuk mengetahui dampak pemberian metode latihan drill dan strokes terhadap ketepatan arah smash pada perrmainan bulutangkis.Penelitian ini merupakan penelitian eksperimen two group pretest-posttest design dengan perlakuan sebanyak 16 kali. Subjek dalam penelitian ini yaitu atlet UKM bulutangkis Universitas Muhammadiyah Surakarta sebanyak 14 atlet. Instrument yang digunakan yaitu dengan tes ketepatan smash oleh Saleh Anasir (2010) dengan validitas 0,926 dari criterion round robin tournament dan relibilitas 0,97 dari test-retest. Teknik analisis data menggunakan uji normalitas dan uji homogenitas, setalah itu dilanjutkan dengan analisis uji-t. Hasil penelitian memperlihatkan bahwasanya terdapat dampak metode latihan drill terhadap ketepatan arah smash dengan nilai t hitung -17,324 < t tabel -2,447 dan nilai signifikansi 0,000<0.05, dengan peningkatan presentase sebanyak 68,53%. Selain itu, juga terdapat dampak metode latihan strokes terhadap ketepatan arah smash dengan nilai t hitung -9,295 < t tabel -2,447 dan nilai signifikansi 0,000<0.05. Kesimpulannya metode latihan drill lebih berdampak terhadap ketepatan arah smash daripada metode latihan strokes dengan selisih rerata posttest sebanyak 3,143.

Oscar Wilde’s Misattributions: A Legacy of Gross Indecency

Drawing on correspondence and periodical advertising as well as paratextual and bibliographic detail, this paper compares editions of the three most prominent texts falsely associated with Oscar Wilde: The Green Carnation (1894), an intimate satire on Wilde’s relationship with Lord Alfred Douglas actually written by Douglas’ friend Robert Smythe Hichens; “The Priest and the Acolyte” (1894), a paedophilic story written by John Francis Bloxam and presented as evidence against Wilde during his libel trial and then privately reprinted; and the erotic novel Teleny (1893), which is still attributed to Wilde today. His name appeared in tandem with these novels over the course of a century, linking him further with sex and scandal. Two separate editions of Teleny in 1984 and 1986 feature introductions by Winston Leyland and John McRae, respectively justifying Wilde’s authorship and describing the work as likely a round-robin pornographic collaboration between Wilde and his young friends. By recognising and exposing these cases of literary impersonation, we can amend Wilde’s legacy.
