[Gems-users] opal and benchmarks

["Sudharsan Rangarajan" <sudrang@xxxxxxxxxxxx>]

Hello,

Im very confused on how to run benchmarks on opal. I am trying to run gzip from SPECint 2000. Ive a binary for SPARC and a magic_call binary.

Since im not going to use ruby, i did not try to warm up caches. Instead i ran the program once as

simics> magic-break-enable

./gzip < ./gzip.source ; magic_call

and then did

simics> write-configuration gzipsol

 

I did not load ruby/opal to do this.

 

I then did

 

simics> read-configuration gzipsol

simics> istc-disable

simics> dstc-disable

simics> instruction-fetch-mode instruction-fetch-trace

simics> load-module opal0

simics> opal0.init

simics> opal0.sim-start "gzip.opal"

simics> opal0.sim-step 10000000000

 

Somethings been running for the last 1 hr, the program runs in a sec or two on a alpha 466Mhz processor that ive.

 

I do not understand the magic_call and the checkpointing. The checkpoint basically holds the state of the machine, and the magic_call just causes a break to simics.

How are we running the simulation? It could be the case only if simics stores a entire history of commands in the checkpoint file. I am new to both simics and gems, some help would be greatly appreciated.

 

Thanks,

Sudharsan
