HPE Cray Programming Environment 21.09 Release Notes
====================================================
Abnormal Termination Processing (ATP) 3.14.5:
================================================
Release Date:
--------------
August 2021
Product Description:
--------------------
Abnormal Termination Processing (ATP) is a system that
monitors user applications, and should an application
take a system trap, ATP preforms analysis on the dying
application. All of the stack backtraces of the
application processes are gathered into a merged
stack backtrace tree and written to disk as the file
"atpMergedBT.dot". The stack backtrace for the first process
to die is sent to stderr as is the number of the signal that
caused the death. If the core file size limit (RLIMIT_CORE)
is non-zero, a heuristically selected set of processes dump
their core.
atpMergedBT.dot can be viewed with 'statview', a component
of the STAT package (module load stat). The merged stack
backtrace tree provides a concise, yet comprehensive, view
of what the application was doing at the time of its death.
Purpose:
---------
This release includes the following new features and bugfixes:
- Full support for CPU and GPU kernel debugging on AMD GPUs
using the ROCm runtime.
- Support analysis of binaries built with PGI and Intel compilers.
Note: there is a known issue with corefile generation for Intel-
built binaries. If corefile support is desired, set
ATP_GDB_BINARY to the path to your system's GDB binary.
Product and OS Dependencies:
-----------------------------
The ATP 3.14.5 release is supported on the following Cray systems:
- HPE/Cray XC systems with CLE release 7.0 or later
- HPE/Cray CS systems with CentOS/RH 8.0 or later

CCDB 4.12.4:
==================
Release Date:
--------------
August 2021
Product Description:
--------------------
CCDB, Cray's next generation debugging tool extends the comparative
debugging capabilities of gdb4hpc with a Graphical User Interface (GUI)
enabling programmers to compare corresponding data structures
between two executing applications. Comparative debugging assists users with
locating sections of code containing data deviations introduced by algorithm
changes, compiler differences, and porting to new architectures/libraries.
Some features of ccdb include:
* Side-by-side debugging session execution of two parallel applications
* Automatic creation of comparison statements for all local variables in
scope
* Type templates for structured data types to selectively compare members
* Warning/error epsilon tolerance values for floating point comparison
* PBS PRO, MOAB/TORQUE, and SLURM workload manager support
Purpose:
---------
This is a feature and bug fix release.
- CAST-23989 fix eye button in application panel and procset focus display
- Fix installation of multiple versions of ccdb on Shasta.

Cray MPICH 8.1.9:
=======================================
Release Date:
-------------
August 18, 2021
Purpose:
--------
Cray MPICH 8.1.9 is based upon ANL MPICH 3.4a2 with support for libfabric
and is optimized for the Cray Programming Environment.
Major Differences Cray MPICH 8.1.9 from the XC Cray MPICH include:
- Uses the new ANL MPICH CH4 code path and libfabric for network
support.
- Does not support -default64 mode for Fortran
- Does not support C++ language bindings
New Cray MPICH features for HPE Cray EX and Apollo systems:
- Cray MPICH uses the libfabric "verbs;ofi_rxm" provider by default.
This is the supported and optimized OFI libfabric provider for
Slingshot-10 and Apollo systems.
- Cray MPICH offers support for multiple NICs per node. Starting with
version 8.0.8, by default Cray MPICH will use all available NICs on
a node. Several rank-to-NIC assignment policies are supported. For
details on choosing a policy for assigning ranks to NICS, or for
selecting a subset of available NICs, please see the following
environment variables documented in the mpi man page.
MPICH_OFI_NIC_VERBOSE
MPICH_OFI_NIC_POLICY
MPICH_OFI_NIC_MAPPING
MPICH_OFI_NUM_NICS
- Enhancements to the MPICH_OFI_NIC_POLICY NUMA mode have been added.
Starting with version 8.0.14, if the user selects the NUMA policy,
the NIC closest to the rank is selected. A NIC no longer needs to
reside in the same numa node as the rank. If multiple NICs are
assigned to the same numa node, the local ranks will round-robin
between them. Numa distances are analyzed to select the closest NIC.
- Cray MPICH supports creating a full connection grid during MPI_Init.
By default, OFI connections between ranks are set up on demand. This
allows for optimal performance while minimizing memory requirements.
However, for jobs requiring an all-to-all communication pattern, it
may be beneficial to create all OFI connections in a coordinated
manner at startup. See the MPICH_OFI_STARTUP_CONNECT description in
the mpi man page.
- Cray MPICH supports runtime switching to the UCX netmod starting
with version 8.0.14. To do this load the craype-network-ucx module
and module swap between Cray-MPICH and Cray-MPICH-UCX modules. For
more information including relevant environment variables reference
the intro_mpi man page with the Cray-MPICH-UCX module loaded.
- Lmod support for HPE Cray EX starting with Cray MPICH 8.0.16.
Key Changes and Bugs Closed:
----------------------------
