• The new OpenCL ICD model changes the local for vendor-specific libraries under Linux from /usr/lib/OpenCL/vendors to /etc/OpenCL/vendors.
  Also, instead of the actual vendorspecific libraries, .icd files are now used to specify the name of the vendor-specific library. Note this important change before you install the ATI Stream SDK v2.1 on Linux systems.
