SHMEMVV

Verification & Validation (V&V) suite for the OpenSHMEM v1.5 specification

Requirements

• Implementation of the OpenSHMEM v1.5
• CMake 3.10 or greater

Limitations

There are a few limitations to SHMEMVV that are currently being addressed:

• ONLY supports the implementations that adhere to the 1.5 specification, if you try to run this on an older OpenSHMEM implementation, you WILL get compiler errors.

• No debug output or logging.

Building

$ mkdir build
$ cd build
$ export CC=`which oshcc` ; export CXX=`which oshc++`
$ cmake ../

Tests

By default, SHMEMVV will run all the tests, but if you want to only run a specific set or sets of tests, you can use one of these runtime flags. For example, this command will run the tests for the communication/context management routines.

oshrun -np 2 shmemvv --test_comms

Since all the tests need the items within the setup routines, those will be run no matter, regardless of which tests you select.
