The ACM Transactions on Architecture and Code Optimization focuses on hardware, software, and system research spanning the fields of computer architecture and code optimization. Articles that appear in TACO present new techniques and concepts or report on experiences and experiments with actual systems. Insights useful to computer architects, hardware or software developers, system designers and tool builders are emphasized.

TACO 2.0

Over the last two years ACM TACO has optimized its internal processes. Today, the average turnaround time from submission to first response is 55 days which is less than two months. For revised manuscripts, the review process goes even faster. In 2012, most accepted manuscripts went through two rounds of reviews to reach a final decision only 5 months after submission. Accepted manuscripts are printed in the next ACM TACO issue, which means an extra delay of at most 3 months. Hence, excellent manuscripts can make it from submission to print in 6 months; papers needing a major revision will make it to print in at most 9 months. The ACM TACO acceptance rate after two review rounds was 24% in 2011; it is 26% in 2012. We call this ACM TACO 2.0.

ACM TACO 2.0 now has a review cycle and an acceptance rate which is competitive with the best ACM conferences, but without the inconvenient non-negotiable submission deadlines, and with the advantage of being able to revise a paper based on the detailed review reports by carefully selected reviewers, and of being published as soon as it is accepted. On top of that, authors of original work papers get an open invitation to present their paper at the yearly HiPEAC conference, which is the premier European network event on topics central to ACM TACO, attended by more than 500 scientists. There is no obligation to present the paper in order to have the paper published in ACM TACO.

Submissions

Manuscripts can be submitted throughout the year. The manuscript page length is 25 pages. Manuscripts can be either extensions of conference papers, or original work. Authors get the reviews of the first review round back after about 2 monhts. The outcome of the first review round can be accept/minor revision/major revision/reject. Authors of a manuscript with a review outcome minor revision/major revision are invited to resubmit a revised manuscript. The outcome of the second review round can only be accept/minor revision/reject. Revised manuscripts with a minor revision can only be accepted or rejected in the last and final review round.

For the upcoming ACM TACO 2.0 issues, we are calling for high-quality manuscripts on topics included, but not limited to:

    Computer system architectures and processor architectures, including multiprocessors and multithreaded computers
    Interaction of operating systems, compilers, programming languages, and architecture
    Feedback-Directed Software/Hardware Optimization
    Dynamic compilation, adaptive execution, and continuous profiling/optimization
    Virtual machine, binary translation hardware, and software optimizations
    Compiler optimizations that exploit instruction level parallelism, such as software pipelining, global scheduling, register allocation, and memory disambiguation
    Advanced software and hardware speculation, prediction, and predication techniques
    High-performance microarchitecture innovation (e.g., VLIW, superscalar, multithreaded, etc.)
    Architectures and compilers for embedded processors, application specific processors and DSPs, including network and router architectures
    Memory system optimization
    Parallel processing
    Architecture or compiler-based power and energy optimization
    Application characterization and architectural implications
    Performance evaluation and measurement of real systems
    Papers of interest to the SIGMICRO, SIGARCH, and SIGPLAN  community
