Better Support & Performance For OpenACC Kernels Is Coming To GCC

While the GNU Compiler Collection has supported OpenACC for a few years now as this parallel programming standard popular with GPUs/accelerators, the current implementation has been found to be inadequate for many real-world HPC workloads leveraging OpenACC. Fortunately, Siemens has been working to improve GCC's OpenACC kernels support. GCC's existing OpenACC kernels construct has been found to be "unable to cope with many language constructs found in real HPC codes which generally leads to very bad performance." Fortunately, improvements are on the way and could potentially be mainlined in time for next year's GCC 12 stable release. Read more

  • Database containing 106m Thailand travelers' details leaked • The Register

    A database containing personal information on 106 million international travelers to Thailand was exposed to the public internet this year, a Brit biz claimed this week. Bob Diachenko, head of cybersecurity research at product-comparison website Comparitech, said the Elasticsearch data store contained visitors' full names, passport numbers, arrival dates, visa types, residency status, and more. It was indexed by search engine Censys on August 20, and spotted by Diachenko two days later. There were no credentials in the database, which is said to have held records dating back a decade. “There are many people who would prefer their travel history and residency status not be publicized, so for them there are obvious privacy issues,” wrote Comparitech editor Paul Bischoff on the company’s blog.
