901-beta-k is available. This version has an avx2 JE. There are now 3 standard JEs for intel 64 bit platforms. If your hardware supports avx2 (2!:7''), then your JVERSION will indicate j64avx2 after you update to beta-k.
If JVERSION indicates you have beta-h or later, then get the latest with: load'pacman' je_update_jpacman_'' If on an older version, you need a few extra steps: pacman update to the latest base library and restart J load'pacman'' je_update_jpacman_'' NB. 1st time gets nonavx version - restart je_update_jpacman_'' NB. 2nd time might get avx or avx2 - restart ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
