Photo: HMTTv4 on a server collecting traces of DDR4 address and data
HMTT was my Ph.D. project supervised by Prof. Mingyu Chen who is leading a lab of ACS and has been keeping building more advanced HMTT over the past decade. Currently, there are two versions: HMTTv3 supports DDR3-800/1600 and HMTTv4 supports DDR4. HMTT can provide off-chip memory traces of many real-world applications, e.g., SPECCPU, SPECjbb, TPC-H/TPC-C on Oracle, and SPECWeb on Apache, with abundant important information, such as timestamp, pid, cpu-request/io-request, r/w, virt_addr and phys_addr.
