1. Trace collection tool – diskmon [1] Maybe helpful in collecting laptop PC’s trace (p2p, multimedia…)

2. Trace collected by HP Lab namedescription Cello 92~99 [4]Time-sharing system used for simulation, compilation, editing, and mail File System hplajwPersonal workstation OpenMailOne-hour traces from five servers running HP’s OpenMail TPC-C TPC-D300 GB Oracle traces from 1997

3. TPC-C [2]  TPC-C is an on-line transaction processing benchmark.  TPC-D represents a broad range of decision support (DS) applications that require complex, long running queries against large complex data structures

4. Trace collected by BYU [3] PlatformSummaryDescription Redhat Linux (7.0) User desktop and application usage Collected over 3 consecutive days. Contains browser, email, messaging, music listening, and desktop environment usage Redhat Linux (6.2)Developer desktop and application usage Collected over 15 consecutive days. Contains text editor, compiler, IDE, browser, email, and desktop environment usage Redhat Linux (7.1)TPC-C. PostgresDisk trace of the TPC-C database benchmark with 20 warehouses

5. Summary  HP’s trace is for large, complex storage systems  Diskmon can easily use to collect our cases customized trace on windows.  BYU’s trace is relatively small to HP’s, mainly focus on laptop pc, well documented

6. To Do This Week…  Validation and verification of simulation tools  The structure of code  Flow chart of handling a request  Prepare a machine installed linux for coding
