[Difx-users] Issue with generating .difx files using startdifx command {External} {External}

[Phillips, Chris (S&A, Marsfield)]

Could this be an issue between openmpi and mpich. In think most people use openmpi

Subject: [Difx-users] Issue with generating .difx files using startdifx command {External}

Hi difx-users,

I am writing to seek assistance regarding an issue I encountered while using the DiFX software. When I use the DiFX software, I am facing difficulties generating .difx files using the startdifx command. The error message I received during the execution is as follows:

I am using DiFX version 2.6.2 on CentOS 7, with the mpich-4.0.3 MPI library. The command I used is "startdifx -f -n aov070.joblist". However, it seems that the MPI execution encountered parsing errors, preventing the generation of .difx files.

To address this issue, I have taken the following steps but have not found a resolution:

Verified the correctness of the command and parameters used in the startdifx command.
Checked the compatibility between the DiFX version (2.6.2) and the MPI library version (mpich-4.0.3).
Explored potential solutions by consulting relevant documentation and online resources.

I would greatly appreciate any guidance or suggestions you can provide to resolve this issue. If there are any specific troubleshooting steps or alternative configurations I should consider, please let me know. Additionally, if there are any known compatibility issues between DiFX 2.6.2 and mpich-4.0.3, I would be grateful to receive that information.

Thank you in advance for your assistance. I look forward to your prompt response.

Best regards,

De Wu
