Intel is studying all the possibilities to ensure security with Larrabee, as the chip giant is worried that hackers may be able to create the first GPU viruses. X-bit Labs reports sooner or later hackers will find ways to executive malicious programs on GPUs:
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.
