HPE Cray Programming Environment 22.05 Release Notes
====================================================
Abnormal Termination Processing (ATP) 3.14.11:
================================================
Release Date:
--------------
April 2022
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:
---------

CCDB 4.12.11:
==================
Release Date:
--------------
April 2022
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

User and Application Impact:
----------------------------
C++ applications built using CCE 13 or earlier may need to be recompiled due to the significant changes that were necessary to implement C++17. This is expected to be a one-time requirement.
Some non-standard Cray Fortran extensions supporting shorthand notation for logical operations will be removed in a future release. CCE 14 will issue warning messages when these are encountered, providing time to adapt the application to use standard Fortran.

Cray Common Tools Interface (CTI) 2.15.11:
======================================
Release Date:
--------------
April 2022
Product Description:
--------------------
Cray Common Tools Interface (CTI) is a library that abstracts debugger
tool support to a common interface regardless of the underlying work
load manager. It facilitates the staging of files and the launch of
tool daemons on the compute nodes associated with a parallel job.
Options and interfaces can be found in the cti(1) and cti(3) manpages.
Purpose:
---------
22.05 This release adds the following content:
- cti(1) user documentation and cti(3) C API documentation
- Dyninst has been updated to v12.1.0
This release fixes the following bugs:
- PALS' cti_pals_getApid function would not complete properly
- CTI Frontend daemon would sometimes encounter a double-free
upon normal exit. Does not affect running applications or
debugger tools.
22.04 This release adds the following features:
- Update Shasta PALS implementation to use PALS utilities and deprecate
the previous Shasta PALS API
- Update the HPCM PALS implementations to use PALS utilities
This release fixes the following bugs:
- Fix the usage of the `aprun` launcher with HPCM PALS instead of
the default `mpiexec` launcher
- Fix HPCM PALS backend startup when node hostnames are in xname format
22.02 This release is a bugfix release:
- Default Shasta PALS node count in job launches to 1
- Include `--overlap` in Slurm tool daemon launches for Slurm versions
20.11 and above
21.12 This release adds the following features:
- Added user documentation manpage cti(1), and developer
documentation manpage cti(3).
- Preliminary support for the Flux workload manager.
Note that passwordless SSH access to compute nodes must be
configured for Flux support. This limitation will be
removed in a future release.
- Flux, Shasta PALS, and ALPS support can be disabled at
compile-time if development headers are not available.
- Updated gen compilers to cray-gcc-10.3.0
21.11 This bugfix release resolves the following issues:
- Fix potential deadlock during job launch / attach for HPCM PALS systems,
as well as the generic SSH interface
- Fix Slurm job attach when running on compute node where hostname does
not match the Slurm node name
- Add environment variable CTI_SLURM_DAEMON_GRES to set the --gres
for Slurm daemon launches. For Slurm versions 21.08 and newer, this
should be set to an empty string (see SchedMD bug)
https://bugs.schedmd.com/show_bug.cgi?id=12642
21.10 This bugfix release resolves the following issues:
- Added CRAY_CTI_PREFIX and CRAY_CTI_VERSION environment variables to the

gdb4hpc 4.14.0:
======================================
Release Date:
--------------
April 2022
Product Description:
--------------------
gdb4hpc is a GDB-based parallel debugger used to debug applications compiled with
CCE, AOCC, GNU, and Intel Fortran, C and C++ compilers. It allows programmers to
either launch an application or attach to an already running application that
was launched on the system. Additionally, it provides comparative debugging
technology that enables programmers to compare data structures between two
executing applications. Comparative debugging should be used in conjunction
with the CCDB GUI tool accessed by loading the cray-ccdb module.
Some features of gdb include:
* Command line parallel debugger allows for launching/attaching applications.
* Utilizes process sets to operate on a subset of application ranks.
* GDB-like feel, also implements a gdbmode to enable a true parallel gdb.
* GPU debugging is supported for OpenMP 4.0+ GPU directives; OpenMP 5.0 on AMD
and Nvidia GPU's.
* Workload manager support via Common Tools Interface (cray-cti).
Purpose:
---------
22.05 Release updates the minor version as there are significant chages:
- C++ container of containers are correctly supported
- Added support for C++ std::array and std::shared_ptr
- The "difference vector" for array comparisons is now printed as
index/difference pairs instead of long changes of zeros
- <optimized-out> and other gdb errors are handled correctly by
print
- Arrays are printed out in language specific format
- Assertion scripts no longer need a decomposition if the number
of compared ranks is equivalent
- Improved error reporting for assertion scripts
- Add --non-mpi launch option to enforce a start-up barrier without
work load manager support
- Fixed the handling of fully distributed decompositions
- Fixed the handling of C and fortran strings
- Fixed artificial array syntax (myarray[0]@4) requiring quotes
- Dyninst has been updated to v12.1.0
22.04 Release adds the following feature:
- Fix the identification of nodes with AMD GPU's when launching or
attaching with the --gpu option
- Improved error detection and reporting for assertion scripts
- Removed extraneous line number reporting when used within ccdb
- Decompositions now work with C/C++ arrays. The array length
is inferred from the decomposition.
22.02 Release adds the following features:
- Regarding gen compilers cray-gcc-10.3.0
NOTE: If you encounter the following error:
ImportError: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.26' not found
Temporary workaround:
1) export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/gcc/10.3.0/snos/lib64
or
2) module load gcc/10.3.0
21.12 This is bugfix release
- Updated gen compilers to cray-gcc-10.3.0

Cray MPICH 8.1.16:
=======================================
Release Date:
-------------
April 18, 2022
Purpose:
--------
Cray MPICH 8.1.16 is based upon ANL MPICH 3.4a2 with support for libfabric
and is optimized for the Cray Programming Environment.
Major Differences Cray MPICH 8.1.16 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.

MRNET 5.0.2:
======================================
Release Date:
--------------
April 2022
Product Description:
--------------------
MRNet is a customizable, high-performance software infrastructure for
building scalable tools and applications. It supports efficient
multicast and data aggregation functionality using a tree of processes
between the tool's front-end and back-ends. MRNet-based tools may use
these internal processes to distribute many important tool activities,
for example to reduce data analysis time and keep tool front-end loads
manageable.
MRNet-based tool components communicate across logical channels called
streams. At MRNet internal processes, filters are bound to these streams to
synchronize and aggregate dataflows. Using filters, MRNet can efficiently
compute averages, sums, and other more complex aggregations and analyses
on tool data. MRNet also supports facilities that allow tool developers
dynamically load new tool-specific filters into the system.
Purpose:
---------
22.05 This is a feature release.
- Dyninst has been updated to v12.1.0.

Perftools 22.05.0
===============
Release Date: May 5, 2022
Purpose:
========
This is a feature release for the following systems:
- HPE Cray EX and HPE Cray Supercomputer Systems with HPCM
- HPE Cray EX and HPE Cray Supercomputer Systems with CSM
- HPE Apollo 2000 Gen 10 Plus Systems (x86)

- HPE Cray CS Systems with RH 8
Important note:
===============
When cpe-gcc-11.2.0 or cray-gcc-11.2.0 (or later) is installed on a system,
ALL VERSIONS OF PERFTOOLS PRIOR TO 21.09.0 WILL FAIL.
After installing cpe-gcc-11.2.0 or cray-gcc-11.2.0 (or later), all Perftools
versions prior to Perftools-21.09.0 will fail. There is no workaround for this;
perftools-21.09.0 later must be used. Cpe-gcc-11.2.0 and cray-gcc-11.2.0 are
installed as part of the Cray PE-21.09 and later releases.
Key enhancements or changes from the previous release:
======================================================
o CCE 14 support.
Known Issues:
=============
o With the change to the accelerator table from using Host Time to Time, this changes
the functions you might see. The older version with host time, functions with
significant "host time" would attribute time to the calling function of the kernel.
With the new change to Time, they do not take a significant amount of real CPU time.
For AMD GPU kernels, you will now see kernels with hipKernel.kernelname listed in
this table, rather than the calling function. For Nvidia GPU kernels, for now you will
simply see cudaLaunchKernel -- we will be adding kernel name support in the next release.
If you look at the calltree view, you can see the source of the cudaLaunchKernel's.
o Perftools cannot generate accurate trace intercept wrappers for CCE Fortran 12.0
and later. This is a result of misleading DWARF debug information issued by
CCE Fortran 12.0 and later. This issue affects any trace experiment that attempts
to generate trace intercept wrappers for user-defined functions, including
'perftools-lite-events', 'perftools-lite-gpu', 'pat_build -u', 'pat_build -t',
and 'pat_build -T'.
The symptom is often a runtime segmentation fault, however, it is also possible
for the instrumented program to execute successfully, yet produce invalid or
misleading results. C and C++ are not affected. Sampling experiments are not
affected. This issue occurs in all versions of CCE Fortran 12.x, 13.x,
and 14.x. A fix will be provided in a future release of CCE.
The workaround is to add -hfunc_trace to all fortran compilations and add
-w to the pat_build invocation to enable tracing.
o Affinity problems may occur on XC systems running PBS when using
perftools with OpenMP codes. Ensure that 'aprun -cc depth' is used
in this situation.
