Running applications in zsim: specifying location of input files used by applications

[sparsh0mittal]

zsim does not run by traces, so programs have to run on-the-fly.

Many of SPEC application assume certain input files to be in same folder as the one where application is being run. If it try to put those files in main folder, it looks very cluttered, and even then, I don't think it is able to read those files.
Is there an option to specify from where to read the input files.

I tried to use perProcessDir to specify a folder and I put input files there, but could not still run, e.g. gamess.

Any help would be appreciated.

Set sim.perProcessDir = true. Then, create subfolders p0, p1, p2, ... and link or copy your input files there. We launch all our runs using scripts, so each simulation directory is used once. I recommend you script this.

Thanks for the reply.

Actually, I tried that before also and again today, but could not do that. For example, for gamess,
cytosine.2.inp is required which I copied in both main directory and p0 and then gave process0.command:

$DIR/CPU2006/416.gamess/run/gamess_base.x86_64_cyn_gcc461 < $DIR/CPU2006/416.gamess/run/cytosine.2.config

still it exits with the message (line numbers in file are changed)

[H] Creating global segment, 1024 MBs
[H] Global segment shmid = 11960320
[H] LOG(Harness): Created global segment, starting pin processes, shmid = 11960320
[H] Running each process in a different subdirectory

[H] WARN: Segmentation fault

[H] Panic on build/opt/zsim_harness.cpp:97: Child issued a panic, killing simulation

I will be thankful for additional help.

I traced and found that it exits after the following line in pin_cmd.cpp

for (uint32_t i = 0; i < p.we_wordc; i++) {
res.push_back(g_string(p.we_wordv[i])); //does not print beyond this line
}

Hi, I know it has been a long time since this issue was posted, and you may already have solved the problem. I put it here just in case someone else may have the same problem. Actually I encountered this problem too, what I want to mention is that if the command line has input redirect (just like gamess), the process0.input should be used.

Hi, I encountered this problem too, I guess you have already solve it. Please help me show the details. I tried to use perProcessDir = true but it can not works. Thanks!
