Mambo Traces Traces for seven parallel I/O-intensive application which were run on eight nodes of an IBM SP-2. Used the AIX trace utility to trace I/O-related system calls (open, close, read, write and seek). Some characteristics of these traces have been described in this University of Maryland Technical Report. Due to access restrictions, these traces are externally hosted.

Sprite Traces The software for opening these traces no longer functions, so they are currently unreadable. Traces were collected from approximately forty workstations connected to four servers. Further information about the traces is available at the Berkeley site, including documentation, software, and sample code. *Please contact us if you successfully read these traces. May 1991 traces from multiple servers at UC Berkeley. *Please contact us if you successfully read these traces. These traces are stored in a binary format, code for processing them can be found here and the OS is here. 1991 5 months 218 MB
