I attempted to do a parallel load and I got this error message:
bash $ date; time iquery -naq "load(raw, '/local/scidb/test.scidb', -1)"; date Tue Dec 4 15:36:33 EST 2012 UserException in file: src/array/Array.cpp function: merge line: 314 Error id: scidb::SCIDB_SE_MERGE::SCIDB_LE_CHUNK_ALREADY_EXISTS Error description: Merge error. An existing chunk cannot be updated. Failed query id: 1100885561203 real 0m1.007s user 0m0.009s sys 0m0.005s Tue Dec 4 15:36:34 EST 2012
I initially tried it on a system running SciDB 12.3, and then repeated the test on SciDB 12.10. The later system was Ubuntu 12.04.
I prepped my file using csv2scidb, specifying the chunk size as 100000 since I have 11 attributes (on average half the attributes are null). Matching chunk size in the raw array I am loading to.
Any thoughts? Thanks,
