General purpose computing on graphics processing units (GPGPU) is a highly-discussed topic these days. Thanks to multi-core architecture, GPUs can process multi-threaded tasks much more rapidly than central processing units. But while GPGPU technologies provide a number of benefits, they can also harm in case GPUs execute malicious code. Intel Corp. believes that GPU viruses are about to emerge and is taking steps to ensure that its forthcoming Larrabee is secure enough.
自從幾年前GPGPU(General purpose computing on graphics processing units,用於通用目的計算的圖形處理器)概念被提出之後,GPGPU就一直是繪圖業界的熱點話題。眾所周知,得益於多核心結構,GPU在處理多線程任務時比中央處理器來的更快。不過,GPGPU技術在為我們帶來諸多優點的同時也為GPU的可執行惡意代碼提供了滋生的溫床。晶片巨頭Intel認為GPU病毒即將出現,而且他們正在展開一些未雨綢繆的措施,阻止GPU病毒“感染”上他們的首款獨顯方案——Larrabee。
“Without any doubts, as graphics processors get more complex, the question of security will become more and more significant and, perhaps, we will witness the first viruses for the GPU. This is why we are carefully studying all the possibilities to ensure [appropriate] security with Larrabee, both on API and on driver levels,” said Philipp Gerasimov, a software development relations specialist at Intel, during a public discussion of Larrabee at Russian-language Habrahabr web-site.
“毫無疑問,隨著GPU核心架構越來越複雜,GPU的安全性也變得越來越重要,也許,我們將會不久的將來首次目睹GPU被病毒感染的事件。這也是為什麼我們一直在認真研究所有有可能侵犯到Larrabee安全的潛在因素,包括API一級驅動程式”,Intel軟體發展專家Philipp Gerasimov說。
At present graphics cards cannot delete or infect files on personal computers or steal confidential data due to limitations of driver models. Still, as GPUs are gaining functionality these days (e.g., Nvidia recently announced that its GeForce chips will be able to accelerate playback of flash-based content), sooner or later hackers will find ways to use those capabilities in a harmful way. Moreover, since Intel’s Larrabee is x86 compatible, whereas Nvidia promises to run C++ or Fortran code on its next-generation GPUs, developers of viruses are getting a whole new set of opportunities.
目前,由於GPU驅動編寫模式的限制,個人桌上型電腦的顯卡還不能刪除、感染檔、或者盜取機密資料。然而,隨著GPU功能的極具膨脹(比如說,NVIDIA最近表示他們的GeForce晶片將會支援加速基於flash的影片播放功能),無孔不入的駭客們遲早會找到漏洞,通過GPU實施惡意攻擊。而且,由於Intel的Larrabee基於x86架構,而NVIDIA也承諾其下一代GPU將會支援C++語言或者Fortran代碼,這都為“病毒玩家”們提供了不錯的機會。
But GPGPU viruses should not be overestimated. Even though GPUs will be able to execute malicious programs (in fact, certain combinations of shaders can damage graphics chips that are not properly cooled down), there will always be a much more keen executor of harmful programs: the microprocessor, which will still be inside every personal computer.
但也不用太過高估GPGPU病毒, 雖然GPU可以執行惡意程序(事實上, 調用某些流處理器的組合可能會導致冷卻不正常, 進而損壞顯示晶片), 但仍然有一個更具威脅力的執行惡意程序者:每台電腦都會有的微處理器

個人不負責猜測...intel正在偷偷著手研發GPU病毒

或許哪天A/N卡淪陷了 然後Larrabee上�**棶|加上防毒的賣點...
