QUESTION

Having thread-local arrays in cython so that I can resize them?

Asked 2019-Nov-12 at 07:13

I have an interval-treeish algorithm I would like to run in parallel for many queries using threads. Problem is that then each thread would need its own array, since I cannot know in advance how many hits there will be.

There are other questions like this, and the solution suggested is always to have an array of size (K, t) where K is output length and t is number of threads. This does not work for me as K might be different for each thread and each thread might need to resize the array to fit all the results it gets.

Pseudocode:

An usual pattern is that every thread gets its own container, which is a trade-off between speed/complexity and memory-overhead:

there is no need to lock for access to this container, because only one thread accesses it.
there is much less overhead compared to "own container for every task (i.e. every i-value)".

After the parallel section, the data must be either collected in a final container in a post processing step (which also could happen in parallel) or the subsequent algorithms should be able to handle a collection of containers.

Here is an example using c++-vector (which already has memory management and increasing size built-in):

QUESTION

Allen's IntersectsWith operator in q

Asked 2019-Feb-07 at 11:37

I am trying to benchmark Allen's IntersectsWith temporal operator in q on the latest kdb+. Allen's IntersectsWith temporal operator is the union of 11 of the 13 relational interval algebra operators he defines. In effect, it returns all overlapping intervals plus any that touch the ends of the interval. (In this sense, it doesn't exist as a primitive temporal operator).

I have a table holding instrument measurements over an interval (startDate,endDate) - the size of the interval can be dynamic but in the below example it is one minute intervals:

Simple approach(for in-memory table) would be to just iterate over each QueryPeriods and fetch required data. Normally it runs pretty fast and there are certain optimizations that could be done with it.

boost xml serialization fails during compilation

Asked 2017-Apr-13 at 19:37

I am using boost::icl::interval_map, to maintain interval search tree for City and it's high, low temperature. I would like to serialize the interval_map to a file.

The code works for text and binary serialization, however xml serialization fails to compile. Here is the error I get

Your question is partly a duplicate of assertion_failed when using Boost Serialization with xml_oarchive, I think. The compile error is fixed by changing oa << tree to oa << BOOST_SERIALIZATION_NVP(tree). The resulting output archive that I get makes sense:
