Hi,
I'm seeing issues with extremely slow IO on $HPCWORK on login18-1 right now. I'm writing two files there (one only a few K, the other one somewhat larger...)
Right now my process is stuck writing the first (small file) with 146 bytes already written. Meanwhile the process is at 100% CPU (and will be killed at some point).
I can confidently say that my process is not actually CPU-bound at this point in the code and is really just trying to write stuff to this file...
Best, Gereon
Hi,
okay, sorry for that, apparently two issues came together here. I indeed had poor IO performance (I saw that once more with the other, somewhat larger file), but this is gone now. The CPU load was on me...
Best, Gereon
