Summary
- Added DoctorPivot: Tool for investigating measures and post-processors. See DoctorPivot.
- Performance: Fixed performance regressions.
- Measures: Fixed “AddOn Fixed” measure regression.
- Atoti Server: Upgraded to Atoti Server 6.0.11
- VectorExpand performance: Externalized aggregation of bitmaps outside
VectorExpandpost-processor.
VectorExpand performance
In previous versions of SIMM, we aggregated bitmaps within the VectorExpand post-processor itself. Now we have
externalized this aggregation by creating a custom AAggregationFunction for bitmaps called BitmapAggFunction. This
aggregation function is used to build the hidden measure Bitmap which is fed into the VectorExpand post-processor measures.
This change drastically improves the performance involving VectorExpand measures and fixes an issue where sub-select clauses would be ignored by the old methodology.

Summary
- Improvements have been made to the Accelerator-sdk. For more information, see the Migration notes
Known issues
- Updated 2022-09-12: PIVOT-5759 - Attempting to create partitions for reference stores causes a deadlock.
- Update 2022-06-07: We’ve identified a bug in the Frequent Value Compression ActivePivot feature (new since AP 5.10). SIMM 2.0.1.* depends on ActivePivot 5.10.5 and is therefore impacted. We strongly recommend disabling the Frequent Value Compression by setting the following property when launching ActivePivot:
-Dactiveviam.chunk.compression.enabledFrequentValue=0. The next maintenance release of SIMM will include an upgrade to ActivePivot, which resolves this issue.

Updated 2022-09-12: PIVOT-5759 - Attempting to create partitions for reference stores causes a deadlock.
1.2.0
Summary
- Exceptions are no longer thrown by the SIMM measure when you add dimensions below the portfolio-level to your query.
- The Ehcache has been optimized to improve the hit/miss ratio.
- The SIMM, Additional Margin, and Total IM measures no longer return any value at the regualtory bucket level, and the new measure K_generic returns the margin for the buckets.

- You’ll now see a notification in the logs if your vertices are not the same length as your sensitivities, as this indicates that the configuration is off.
- Schedule calculations are only applied to regulations in a trade that are marked as schedule, and SIMM is no longer calculated for these entries.
- Customization of the CrifTuplePublisher class for publishing to new datastores has been made easier.
- WTD_Risk_FX now uses CollectCalculationCcy in its calculation.
