Hello all,
I'm trying to improve the checkpoint/run scripts and one of the big
sticking points is figuring out how many cores the current binary is built
with (I want to annotate the checkpoint names with this value so there's no
confusion). I've come up with a very crude but effective hack and I was
wondering if you guys are OK with it. Just print the static string in the
banner message:
diff --git a/ptlsim/sim/ptlsim.cpp b/ptlsim/sim/ptlsim.cpp
index ee0de41..307fa2b 100644
--- a/ptlsim/sim/ptlsim.cpp
+++ b/ptlsim/sim/ptlsim.cpp
@@ -386,6 +386,7 @@ static void print_banner(ostream& os) {
os << "// Git branch '", stringify(GITBRANCH), "' on date ",
stringify(GITDATE)," (HEAD: ", stringify(GITCOMMIT), ")", endl;
os << "// Built ", __DATE__, " ", __TIME__, " on ",
stringify(BUILDHOST), " using gcc-",
stringify(__GNUC__), ".", stringify(__GNUC_MINOR__), endl;
+ os << "// With " stringify(NUM_SIM_CORES) " simulated cores", endl;
os << "// Running on ", hostinfo.nodename, ".", hostinfo.domainname,
endl;
os << "// ", endl;
os << endl;
And then get it back out with the strings command and grep:
$ strings qemu/qemu-system-x86_64 | grep "simulated cores"
// With 2 simulated cores
Is this too hacky for you guys? Is there some easier way to accomplish this?
-Paul
