AMD has updated the ROCm Radeon Open Compute Linux stack, a global platform for GPU-accelerated computing on Radeon graphics cards.

ROCm 5.5 release

What's New in This Release

HIP Enhancements

The ROCm v5.5 release consists of the following HIP enhancements:

Enhanced Stack Size Limit

In this release, the stack size limit is increased from 16k to 131056 bytes (or 128K - 16).
Applications requiring to update the stack size can use hipDeviceSetLimit API.

hipcc Changes

The following hipcc changes are implemented in this release:

• hipcc will not implicitly link to libpthread and librt, as they are no longer a link time dependence for HIP programs. Applications that depend on these libraries must explicitly link to them.
• -use-staticlib and -use-sharedlib options are deprecated.

Future Changes

• Separation of hipcc binaries (Perl scripts) from HIP to hipcc project. Users will access separate hipcc package for installing hipcc binaries in future ROCm releases.

• In a future ROCm release, the following samples will be removed from the hip-tests project.

  • hipBusbandWidth at  https://github.com/ROCm-Developer-Tools/hip-tests/tree/develop/samples/1_Utils/shipBusBandwidth
  • hipCommander at  https://github.com/ROCm-Developer-Tools/hip-tests/tree/develop/samples/1_Utils/hipCommander

  Note that the samples will continue to be available in previous release branches.

New HIP APIs in This Release

Note

This is a pre-official version (beta) release of the new APIs and may contain unresolved issues.

Memory Management HIP APIs

The new memory management HIP API is as follows:

• Sets information on the specified pointer [BETA].

  hipError_t hipPointerSetAttribute(const void* value, hipPointer_attribute attribute, hipDeviceptr_t ptr);

Module Management HIP APIs

The new module management HIP APIs are as follows:

• Launches kernel � with launch parameters and shared memory on stream with arguments passed to kernelParams, where thread blocks can cooperate and synchronize as they execute.

  hipError_t hipModuleLaunchCooperativeKernel(hipFunction_t f, unsigned int gridDimX, unsigned int gridDimY, unsigned int gridDimZ, unsigned int blockDimX, unsigned int blockDimY, unsigned int blockDimZ, unsigned int sharedMemBytes, hipStream_t stream, void** kernelParams);
  

• Launches kernels on multiple devices where thread blocks can cooperate and synchronize as they execute.

  hipError_t hipModuleLaunchCooperativeKernelMultiDevice(hipFunctionLaunchParams* launchParamsList, unsigned int numDevices, unsigned int flags);
  

HIP Graph Management APIs

The new HIP Graph Management APIs are as follows:

• Creates a memory allocation node and adds it to a graph [BETA]

  hipError_t hipGraphAddMemAllocNode(hipGraphNode_t* pGraphNode, hipGraph_t graph, const hipGraphNode_t* pDependencies, size_t numDependencies, hipMemAllocNodeParams* pNodeParams);

• Return parameters for memory allocation node [BETA]

  hipError_t hipGraphMemAllocNodeGetParams(hipGraphNode_t node, hipMemAllocNodeParams* pNodeParams);

• Creates a memory free node and adds it to a graph [BETA]

  hipError_t hipGraphAddMemFreeNode(hipGraphNode_t* pGraphNode, hipGraph_t graph, const hipGraphNode_t* pDependencies, size_t numDependencies, void* dev_ptr);

• Returns parameters for memory free node [BETA].

  hipError_t hipGraphMemFreeNodeGetParams(hipGraphNode_t node, void* dev_ptr);

• Write a DOT file describing graph structure [BETA].

  hipError_t hipGraphDebugDotPrint(hipGraph_t graph, const char* path, unsigned int flags);

• Copies attributes from source node to destination node [BETA].

  hipError_t hipGraphKernelNodeCopyAttributes(hipGraphNode_t hSrc, hipGraphNode_t hDst);

• Enables or disables the specified node in the given graphExec [BETA]

  hipError_t hipGraphNodeSetEnabled(hipGraphExec_t hGraphExec, hipGraphNode_t hNode, unsigned int isEnabled);

• Query whether a node in the given graphExec is enabled [BETA]

  hipError_t hipGraphNodeGetEnabled(hipGraphExec_t hGraphExec, hipGraphNode_t hNode, unsigned int* isEnabled);

OpenMP Enhancements

This release consists of the following OpenMP enhancements:

• Additional support for OMPT functions get_device_time and get_record_type.
• Add support for min/max fast fp atomics on AMD GPUs.
• Fix the use of the abs function in C device regions.

Deprecations and Warnings

HIP Deprecation

The hipcc and hipconfig Perl scripts are deprecated. In a future release, compiled binaries will be available as hipcc.bin and hipconfig.bin as replacements for the Perl scripts.

Note

There will be a transition period where the Perl scripts and compiled binaries are available before the scripts are removed. There will be no functional difference between the Perl scripts and their compiled binary counterpart. No user action is required. Once these are available, users can optionally switch to hipcc.bin and hipconfig.bin. The hipcc/hipconfig soft link will be assimilated to point from hipcc/hipconfig to the respective compiled binaries as the default option.

Linux Filesystem Hierarchy Standard for ROCm

ROCm packages have adopted the Linux foundation filesystem hierarchy standard in this release to ensure ROCm components follow open source conventions for Linux-based distributions. While moving to a new filesystem hierarchy, ROCm ensures backward compatibility with its 5.1 version or older filesystem hierarchy. See below for a detailed explanation of the new filesystem hierarchy and backward compatibility.

New Filesystem Hierarchy

The following is the new filesystem hierarchy:4

/opt/rocm-<ver&rt;
    | --bin
      | --All externally exposed Binaries
    | --libexec
        | --<component&rt;
            | -- Component specific private non-ISA executables (architecture independent)
    | --include
        | -- <component&rt;
            | --<header files&rt;
    | --lib
        | --lib<soname&rt;.so -&rt; lib<soname&rt;.so.major -&rt; lib<soname&rt;.so.major.minor.patch
            (public libraries linked with application)
        | --<component&rt; (component specific private library, executable data)
        | --<cmake&rt;
            | --components
                | --<component&rt;.config.cmake
    | --share
        | --html/<component&rt;/*.html
        | --info/<component&rt;/*.[pdf, md, txt]
        | --man
        | --doc
            | --<component&rt;
                | --<licenses&rt;
        | --<component&rt;
            | --<misc files&rt; (arch independent non-executable)
            | --samples
            

Note

ROCm will not support backward compatibility with the v5.1(old) file system hierarchy in its next major release.

For more information, refer to  https://refspecs.linuxfoundation.org/fhs.shtml.

Backward Compatibility with Older Filesystems

ROCm has moved header files and libraries to its new location as indicated in the above structure and included symbolic-link and wrapper header files in its old location for backward compatibility.

Note

ROCm will continue supporting backward compatibility until the next major release.

Wrapper header files

Wrapper header files are placed in the old location (/opt/rocm-xxx//include) with a warning message to include files from the new location (/opt/rocm-xxx/include) as shown in the example below:

// Code snippet from hip_runtime.h
#pragma message “This file is deprecated. Use file from include path /opt/rocm-ver/include/ and prefix with hip”.
#include "hip/hip_runtime.h"

The wrapper header files’ backward compatibility deprecation is as follows:

• #pragma message announcing deprecation -- ROCm v5.2 release
• #pragma message changed to #warning -- Future release
• #warning changed to #error -- Future release
• Backward compatibility wrappers removed -- Future release

Library files

Library files are available in the /opt/rocm-xxx/lib folder. For backward compatibility, the old library location (/opt/rocm-xxx//lib) has a soft link to the library at the new location.

Example:

$ ls -l /opt/rocm/hip/lib/
total 4
drwxr-xr-x 4 root root 4096 May 12 10:45 cmake
lrwxrwxrwx 1 root root   24 May 10 23:32 libamdhip64.so -> ../../lib/libamdhip64.so

CMake Config files

All CMake configuration files are available in the /opt/rocm-xxx/lib/cmake/ folder.
For backward compatibility, the old CMake locations (/opt/rocm-xxx//lib/cmake) consist of a soft link to the new CMake config.

Example:

$ ls -l /opt/rocm/hip/lib/cmake/hip/
total 0
lrwxrwxrwx 1 root root 42 May 10 23:32 hip-config.cmake -> ../../../../lib/cmake/hip/hip-config.cmake
