| [ptp-user] PTP fails to connect to debugger |
| Dear PTP users, I am writing this email to ask for help in setting up a debugging environment for openMPI-based applications. Currently, I am struggling with a problem that is hampering me from continuing the work. The problem is very similar to what has been posted on the stackOverFlow (See: Link). Its symptom is that the debugging process hangs and the parallel debugging perspective shows a “Operation in progress…” message. It is caused by an error, namely “Cannot connect to debugger”. Meanwhile, an error message “getaddrinfo: Undefined error: 0” also appear in the debugging console. I did some search on the internet and I found an instruction for trouble shooting (See: Link). I already verified that: 1) Launch script could work: non-debug launch works fine; 2) Correct number of “sdm” processes; 3) Routing file can be created; But I could not find one “sdm” process with argument “—master”. Currently, I use the following software components with indicated versions: 1) Parallel Tools Platform including PTP Parallel Language Development Tools, etc. (9.0.1.201509091505); 2) ptp-sdm-9.0.0 (org.eclipse.ptp.macosx_9.0.0.201506101404); 3) GNU gdb (7.10); The OS I am using is OS X Yosemite (10.10.5). And I run application on the local machine. Did any other PTP user encounter the similar problem and happen to know how to fix it? I would appreciate any hint or help from you. Best regards, Tao Li TU Dresden |
