Intel® Dynamic Application Loader (Intel® DAL) supports both shared and non-shared sessions (in which a host application uses the Intel® DAL Host Interface Service (Intel® DAL HIS) to communicate with a trusted application)
  • Non-shared session: A session that is used exclusively by 1 host application.
  • Shared session: A session that is used by 1 or more host applications.
The following table shows the maximum number of open sessions to the Intel DAL virtual machine for each firmware generation and API level:

Product and Performance Information


Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
