On 4xxx __local mem is really __global mem ( ATI thinks it's too much work to optimize compiler to use 48xx LDS - although it's possible ). On 5xxx __local is LDS - so it's located in simd core. }}} == Catalyst 10.1 with Ubuntu 9.10 workarounds == === Change the kernel boot option === Edit "/etc/default/grub" and execute update-grub. I add "nopat" to GRUB_CMDLINE_LINUX_DEFAULT for Catalyst 10.1. The configuration file for the grub is at /boot/grub/grub.cfg. This file is automatically generated by update-grub command. This trick is not necessary for Catalyst 10.2. === X server setting === The default login manager gdm is difficult to properly configure, I install xdm instead of gdm. The configuration file for xdm is at /etc/X11/xdm directory. Edit "Xservers" file as {{{ :0 local /usr/bin/X :0 vt7 -nolisten tcp -ac }}} This "-ac" option enable remote applications to access the local X server. Note this option is generally regarded as "bad" for security. Be careful. === icc === http://software.intel.com/en-us/articles/using-intel-compilers-for-linux-with-ubuntu/
