Introduction: Who Wants V1.1?

SPEC ACCEL V1.1 is an incremental update to SPEC ACCEL V1.0. Results generated with V1.1 are comparable to results from V1.0 and vice versa. V1.1 is intended to improve compatibility, stability, documentation and ease of use. Changes are intended to be useful to several kinds of users:

For users of new platforms:

• Updates to 24 benchmarks, primarily to improve portability and fix bugs.
