It looks like DDT's installed on JLSE in /soft/debuggers/ddt/bin/ddt. But when I tried to run it, I got the error: "Error communicating with Licence Server ftsn3.ftm.alcf.anl.gov: Host unreachable". Maybe there is no license for JLSE? I know DDT works on Theta for debugging KNL, at least. ________________________________ From: [email protected] [[email protected]] on behalf of Banerjee,Tania [[email protected]] Sent: Monday, May 08, 2017 10:41 AM To: [email protected] Subject: [JLSE-Intel-NDA] Debugging on KNL Hi, I want to debug a segmentation fault on KNL.
