QuickHash 3.3.2 download2/19/2024 ![]() ![]() The user can run both the 32 and 64 bit executables on a single Windows 64 machine, even at the same time. On most Windows systems, if the user extracts the whole zip file (including the "libs" folder) to a new folder or their desktop, it should just run. The download includes both a 64-bit and 32-bit edition of the software with accompanying DLL's and user manual (in English - a French version for v3.3.1 is currently available too for French speaking users, HERE). Please refer “Centralized Cache Management” guide for more details.This download is for the Windows version of Quickhash-GUI. Once the InputStream is created, DataNode will send the cached data to the client. When DataNode receives a data read request from a client, if the corresponding block is cached into SCM, DataNode will instantiate an InputStream with the block location path on SCM (pure java implementation) or cache address on SCM (PMDK based implementation). Consistent with DRAM cache, SCM cache also has no cache eviction mechanism. If multiple SCM volumes are configured, a round-robin policy is used to select an available volume for caching a block. Then, build Hadoop with PMDK support by referring to “PMDK library build options” section in `BUILDING.txt` in the source code. To enable PMDK based implementation, user should install PMDK library by referring to the official site. If PMDK native libs could be loaded, it will use PMDK based implementation otherwise it will fallback to java code implementation. The latter implementation can bring user better performance gain in cache write and cache read. There are two implementations for HDFS SCM Cache, one is pure java code implementation and the other is native PMDK based implementation. And all HDFS cache directives keep unchanged. To enable SCM cache, user just needs to configure SCM volume for property “.dirs” in hdfs-site.xml. ![]() ![]() Non-volatile storage class memory (SCM, also known as persistent memory) is supported in HDFS cache. ![]() Running Applications in Docker Containersīackport HDFS persistent memory read cache support to branch-3.2**. ![]()
