Dear David,
I tried with --progress but untill 48 cores it was showing the error
"FATAL: allocation failure in ivector()" .
The memory information is as follows:
1. Master Node: 94 GB
2. CPU Node: 94 GB (X6)
3. GPU Node: 64 GB (X3)
As per your suggestion I have attached my PDB file with this mail.

Thanks,
Priti
