We have an amazon ec2 32 node cluster, each has 61430MB of RAM (as reported by free -m). I am configuring 3 instances per node. As I type scidb.py initall aesdb, it hangs for an hour (I went to a meeting and it was hanging)
There was no new information in /data/scidb/0/000/
the scidb.log was not regenerated, and there were no new files.
/opt/scidb is owned by user scidb.
ssh localhost and 127.0.0.1 as well as between all hosts works without password.
What can I check to see why it is hanging?
Here is the config.ini file:
Threading: max_concurrent_queries=2, threads_per_query=2
max_concurrent_queries + 2:
max_concurrent_queries * threads_per_query:
Memory: 20476MB per instance, 15357MB reserved
network: 6143MB per instance assuming 5MB average chunks
in units of chunks per query:
caches: 6143MB per instance
sort: 3071MB per instance (specified per thread)
NOTE: Uncomment the following line to set a hard memory limit;
NOTE: queries exceeding this cap will fail:
I can’t figure this out. I have done this a million times, but now it is hanging …
