In contrast to previous approaches we do not rely on either software or hardware speculation that can be detrimental to efficiency. While out-of-order (OoO) architectures attempt to hide memory latency by dynamically reordering instructions, they do so through expensive, power-hungry, speculative mechanisms.We aim to shift this complexity into software, and we build upon compilation techniques inherited from VLIW, software pipelining, modulo scheduling, decoupled access-execution, and software prefetching. Our approach is able to hide memory latency and attain increased memory and instruction level parallelism by orchestrating a non-speculative, execute-ahead paradigm in software (SWOOP). In this paper, we address one of the main performance bottlenecks - last-level cache misses - through a software-hardware co-design. We propose a cross-layer redesign of the way compilers and the underlying microarchitecture are built and interact, to achieve both performance and high energy efficiency. These new hardware trends challenge the established assumptions in code generation and force us to rethink existing software optimization techniques. Fix save path history problem (v2.Increasing demands for energy efficiency constrain emerging hardware. Append selected folder to source field, if it is pushed OK button in Source Folder Select Dialog with pushing CTRL key.It operates lightly because MFC is not used, and it makes it only from Win32 API.īecause all source codes have been opened to the public in the BSD license, you can modify this software. Include/Exclude Filter (UNIX Wildcard style) can be specified. Read/Write performance is a near the limit of the device. Same HDD: Using big buffer, reading until the buffer becomes full, and writing in bulk.īecause Read/Write doesn´t use the cache of OS at all, other processes (application) do not become heavy easily.Diff HDD: Reading and writing are done with the MultiThreading in parallel.It can copy/delete unicode and over MAX_PATH(260byte) pathname files.Īutomatically, after whether the copy origin and copy destinations are HDD according to same physical HDD or is judged, it operates as follows. An extremely fast Copy/Delete software for Windows.įastCopy is the Fastest Copy/Delete Software on Windows.
