Resources for project work
This page is still somewhat construction...
We have acquired a 2 GB disk for use by the class during the course of the
semester. The disk is at /disks/stampede/sandbox2/. This will
(hopefully) very shortly be accessible from the dawn machines on the NOW cluster. The machines
dawn0 through dawn31, which are SPARC workstations running
Solaris 2.4, can be used for cs252 project work.
has to be shared amongst the whole class. I will not be setting up any
quotas, so you're on your own to be courteous to others. (I will try to set
something up that periodically collects stats on disk usage, so you can see
who's hogging all of the space.) Make sure not to
leave large core files laying around, and use local scratch space for large,
temporary files. The following scratch areas (i.e. not backed up) are
Everyone in the class will have directories within /disks/stampede/sandbox2/cs252/.
For those of you that already have CS accounts, when you log into the dawn
machines, your home directory will be the same as what it currently is. For
those of you that have guest accounts (which will expire once the semester
is over), you home directory will be within /disks/stampede/sandbox2/cs252/.
There is a generic class directory, /disks/stampede/sandbox2/cs252/cs252/.
Various tidbits of information, including links to tools, benchmarks, and other useful
directories, can be found there.
Some of you have much more disk space available to you than others. If you do
not really need to use the disk space on stampede, please consider
using space elsewhere so that those students whose home directories are on file
systems that are always stuck at 100% capacity have more of an opportunity
for space. Remember that you all have 20 MB of storage available on the
Note that you are not limited to using just the dawn machines for
cs252 work. You can use any resources that are at your disposal - this
department has a wide variety of machines, including SPARC, HP, DEC MIPS,
DEC Alpha, SGI, and x86. Some tools work on some machines and not on others.
- Tools: a short story, by Remzi Arpaci, briefly
describes pixie, pixstats, prof, dinero, qpt, CPROF, spim, Cacti, shade,
and spixtools. Most of the specific directories and files mentioned are
on the instructional machines.
Wisconsin Architectural Research Tool Set (WARTS)
- including QPT, QPT2, CPROF, Tycho, dineroIII, and EEL
- ATOM - A toolkit that can be used for tracing, and much more.
Only runs on Alphas. Log in to either saidin.eecs (an instructional machine) or speeding.cs
(on the same file system as the NOW machines)
- EEL - A toolkit that can be used for tracing, and much more.
Only runs on SPARCs.
See the following
class project for some more details.

or Linux. Courtesy of Harvard University and the University of Washington.
Instruction-Level Simulation And Tracing
- This contains a huge list of simulators, emulators, and tracing tools,
including an extensive bibliography as well as list of people to contact
- Etch Traces
- user level traces of Windows NT applications collected using Etch.
- Monster Traces - Traces of 8 applications (run under Ultrix and Mach)
collected with a hardware monitor on a DEC-MIPS workstation. Includes
user and kernel activity. First presented in a
paper which appeared in
ISCA95. Courtesy of Richard Uhlig (thanks to
Christoforos for getting them). More details forthcoming when these
are actually available.
- Patchwrx - Single-processor portions of traces, containing user and kernel
references, from 2 spec benchmarks and a database, running under Windows
NT on an Alpha. Courtesy of Dick Sites, from DEC. A few projects from
last spring's IRAM class as well as a Spring 1996 CS 252 projects detail
some caveats concerning the accuracy of these traces (and of Dick Sites'
conclusions regarding "Caches Don't Work".)
New Mexico State Univ Trace Database
CPU Info Center has a good summary of high-level info
- MIPS does a very good job of
providing on-line documentation
- Intel's web page is generally full of marketing crap, but there's a neat
Intel Secrets page, which is subtitled
"What Intel Doesn't Want You To Know"
- I have some hardcopy documentation on DEC Alpha microprocessors. I
am willing to briefly loan them for making selective copies, or I can
provide you with information as to how you can order (for free) your
