\nGNU developers today released GNU C Library “glibc” 2.44 as the newest feature release for this critical library to modern Linux systems and other platforms.<\/p>\n

Among the new features in Glibc 2.44 is introducing \/etc\/tunables.conf for storing new system-wide tunables<\/a> for the GNU C Library. This is an alternative and more persistent option than the existing GLIBC_TUNABLES= environment variable option. With \/etc\/tunables.conf you can store one tunable per line and a variety of filters and other options can be applied.
\n<\/p>\n

\"\/etc\/tunables.conf\"\/<\/p>\n

Glibc 2.44 also introduces a FMA’ed cosh implementation for a ~35% improvement<\/a>. More optimized and correctly-rounded math functions have also been imported from the CORE-MATH project. There are also new optimizations for LoongArch CPUs<\/a> as well as introducing LoongArch32 32-bit support. Various functions have also now been better optimized on AArch64 and RISC-V.<\/p>\n

More details on the many changes to find with today’s GNU C Library 2.44 release can be found via the mailing list announcement<\/a>. Glibc 2.44 will be working its way into the likes of Ubuntu 26.10, Fedora 45, and other upcoming Linux distribution releases.<\/p>\n","protected":false},"excerpt":{"rendered":"GNU developers today released GNU C Library “glibc” 2.44 as the newest feature release for this critical library…\n","protected":false},"author":2,"featured_media":558847,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6],"tags":[78437,85,46,78436,78434,78433,78440,78438,78435,78439,78432,78443,125,78441,78442],"class_list":["post-558846","post","type-post","status-publish","format-standard","has-post-thumbnail","category-technology","tag-desktop-linux","tag-il","tag-israel","tag-linux-benchmarking","tag-linux-hardware-benchmarks","tag-linux-hardware-reviews","tag-linux-how-to","tag-linux-performance","tag-linux-server-benchmarks","tag-open-source-graphics","tag-phoronix","tag-phoronix-test-suite","tag-technology","tag-ubuntu-benchmarks","tag-ubuntu-hardware"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/558846","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/comments?post=558846"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/558846\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media\/558847"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media?parent=558846"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/categories?post=558846"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/tags?post=558846"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
