Parallel computing is a rapidly evolving field that is an essential ingredient in all aspects of computer science. ACM Transactions on Parallel Computing (TOPC) is a forum for novel and innovative work on all aspects of parallel computing, including foundational and theoretical aspects, systems, languages, architectures, tools, and applications. It addresses all classes of parallel-processing platforms including concurrent, multithreaded, multicore, accelerated, multiprocessor, clusters, and supercomputers. TOPC spans the range from foundational research in parallel computing to principles extracted from experimental investigations. Submissions should describe novel solutions to important challenges in exploiting parallelism. Solutions should be generic enough to be used beyond the specific application area in which the problem arose. Papers describing experiences should indicate how they illustrate general principles; papers about parallel computing foundations should indicate how they relate to practice. Subject Areas Parallel Programming Languages and Models Parallel System Software Parallel Architectures Parallel Algorithms and Theory Parallel Applications Tools for Parallel Computing

Only articles that were accepted and published are counted, not the time spent on rejected manuscripts, so this usually runs longer than a publisher's "time to first decision".
Community reports come from authors' own submissions (confidence 0.5) and are not a promise from the journal; for publisher figures, the journal's own definitions apply.
Fees & open access
APC and open-access policy
Hybrid open accessLetPub
A subscription journal in which authors can pay to publish their article open access.
No source has fee information yet; check the journal's website.
A hybrid journal charges the APC only when the author chooses open access; publishing under the subscription model is usually free.
The journal's website is authoritative for fees; sources were observed at different times and each keeps its own value, without averaging.
