Version 13.9 of SciDB is now available for download. We support three platforms: Ubuntu 12.04, RHEL 6, and CentOS 6.
The Community Edition of SciDB 13.9 includes:
- A new aggregate operator, cumulate, which computes cumulative aggregates along a user-supplied dimension
- Significant performance improvements in the redimension() and redimensione_store() operators.
- A new required configuration parameter, enable-catalog-upgrade.
- The special value NA, which remains in the product but has been deprecated. It will be removed from the product for version 13.12.
- The multiply operator, which remains in the product but has been deprecated. It will be removed from the product for 13.12. To multiply dense matrices, use the gemm() operator. To multiplye sparse matrices, use the spgemm() operator, which is available only in the Enterprise Edition.
The Enterprise Edition of SciDB 13.9 includes:
- A new operator spgemm() for sparse matrix multiply.
- New capabilities for the timestamp data type. It now suports a coersion from the SciDB string type whose argument is a string representation of a date-time pair.
- Some renaming for clarity. In previous versions the names “first” and “last” were used both as function as aggregates. IN 13.9, the aggregate names are “first_value” and “last_value.”
- Deprecated operators, which will be removed in version 13.12. Both cumsum() and cumprod() are deprecated; use cumulate() instead. Both linregr() and logistregr() are deprecated; use glm() instead. And solve() is deprecated; use gesvd() instead.
