[Condor-users] First go at standard Universe checkpointing

[Ian Cottam <Ian.Cottam@xxxxxxxxxxxxxxxx>]

I'm trying to get my first Standard Universe job working, because of
checkpointing (Condor 7.4.4 RedHat build).

I've replicated the problems I'm having by means of a tiny C program. Said
problems being...
- the check point file ends in .tmp and seems far too small; and
- when I restart the test case it immediately seg faults.

Any ideas?

Test code looks like this----
#include <stdio.h>
#include <math.h>
int main(void)
{
 int i; double x;
 FILE *f= fopen("r-out.txt", "w");
 fputs("hello Condor Standard Universe - starting\n", f);
 for (i= -500000000; i != 500000000; ++i) {
  x= sqrt(i<0?-i:i); /* kill some time */ 
 }
 fputs("finished OK\n", f);
 return 0;
}


---

Compiled with---
condor_compile gcc cctest.c -o cctest -lm
---
I'm testing by just doing a standalone
./cctest

Followed by a control-Z to make it checkpoint and quit.


Thanks for suggestions in advance!
