The has added an automatic test and code report generation feature, code timer consolidation, an updated README, two new code examples (diagonal sparse matrix vector multiplication and conjugate gradient) and an examples Makefile.

The has incorporated all of the changes to 'master' and new OpenSHMEM 1.4 features including: extended atomic memory operations, remote memory operations, point-to-point synchronization operations, a calloc routine, and other minor specification changes. Since the full OpenSHMEM v 1.4 specification has not been ratified yet, this new branch was created to incorporate the changes that have passed the committee vote. Once v. 1.4 is ratified, the 'master' branch will merge these changes.

Feedback is welcome.

The main fix had to do with the LDF loader and the _end symbol needed to build the brk/sbrk routines for memory management. Ola pointed me in the right direction.

Memory management should be the only difference between the eSDK/COPRTHR flavors of the library.

If you find any, please report bugs through github.

I've also provided a for using the library with the eSDK.

It's similar to the except that it now performs initialization and a non-trivially parallel reduction across all cores. Rather than each core performing a local summation and having the ARM host perform the final summation, this operation is performed in parallel on the Epiphany device.
