Product     : Fedora 24
Version     : 1.0

Summary     : C++ library of special-purpose memory allocators
Description :
Memtailor is a C++ library of special purpose memory allocators.  It
currently offers an arena allocator and a memory pool.

The main motivation to use a memtailor allocator is better and more
predictable performance than you get with new/delete.  Sometimes a
memtailor allocator can also be more convenient due to the ability to
free many allocations at one time.

The Memtailor memory pool is useful if you need to do many allocations
of a fixed size.  For example a memory pool is well suited to allocate
the nodes in a linked list.

You can think of the Memtailor arena allocator as being similar to stack
allocation.  Both kinds of allocation are very fast and require you to
allocate/deallocate memory in last-in-first-out order.  Arena allocation
has the further benefits that it stays within the C++ standard, it will
not cause a stack overflow, you can have multiple arena allocators at
the same time and allocation is not tied to a function invocation.

Update Information:

The tbb update simply adds -fno-delete-null-pointer-checks to the build flags.
The previous build showed some odd behavior when used by mathicgb, but behaves
as expected when built with this flag.  The memtailor, mathic, and mathicgb
updates move to the latest upstream git snapshots in preparation for using these
packages for the latest Singular and Macaulay2 releases.

This update can be installed with the "yum" update program. Use
su -c 'yum update memtailor' at the command line.
