 Posted: Sat Jul 15, 2023 4:04 pm Post subject: Folding@Home crashes in libstdc++ during AMD ROCm/HSA call |
 |
|
I'm trying to run sci-biology/foldingathome-7.6.21 on an AMD gfx906 ("AMD Radeon Pro VII") GPU using ROCm/HSA 5.4.3 in the official Gentoo repository. Unfortunately, FAHClient crashes as soon as it tries to invoke to detect and initialize the GPU via ROCm/HSA. Other OpenCL and HIP programs, such as clpeak, or my own SYCL program (targeting AMD HIP), runs on the same system without problems.
| Code: |
user@gentoo /opt/foldingathome $ ./FAHClient
15:44:17:Read GPUs.txt
Segmentation fault (core dumped)

I recompiled dev-libs/rocr-runtime-5.4.3-r1, dev-libs/rocm-opencl-runtime, dev-libs/rocm-opencl-runtime with debug symbols and source code enabled, and gdb was able to generate the following backtrace:

As one can see from the backtrace, FAHClient invokes ROCm/ROCr/HSA to query the GPU, but the shared library rocr-runtime crashes during this process. The offending lines is amd_gpu_agent.cpp:1052:
| Code: |
1038 case HSA_AMD_AGENT_INFO_UUID: {
1039 uint64_t uuid_value = static_cast<uint64_t>(properties_.UniqueID);
1040
1041 // Either device does not support UUID e.g. a Gfx8 device,
1042 // or runtime is using an older thunk library that does not
1043 // support UUID's
1044 if (uuid_value == 0) {
1045 char uuid_tmp[] = "GPU-XX";
1046 snprintf((char*)value, sizeof(uuid_tmp), "%s", uuid_tmp);
1047 break;
1048 }
1049
1050 // Device supports UUID, build UUID string to return
1051 std::stringstream ss;
1052 ss << "GPU-" << std::setfill('0') << std::setw(sizeof(uint64_t) * 2) << std::hex
1053 << uuid_value;
1054 snprintf((char*)value, (ss.str().length() + 1), "%s", (char*)ss.str().c_str());
1055 break;
1056 }
|
It crashes while rocr-runtime tries to convert the GPU UUID into a string, at these two lines:
| Code: |
1052 ss << "GPU-" << std::setfill('0') << std::setw(sizeof(uint64_t) * 2) << std::hex
1053 << uuid_value;
|
According to gdb, it crashes inside std::setfill('0'):
| Code: |
#0 0x0000000000000000 in ?? ()
#1 0x00007ffff6cd1821 in std::ctype<char>::_M_widen_init() const () from /usr/lib/gcc/x86_64-pc-linux-gnu/12/libstdc++.so.6

at /usr/lib/gcc/x86_64-pc-linux-gnu/12/include/g++-v12/bits/basic_ios.h:390
|
If I debug frame #5, one can see that the GPU UUID is succesfully detected, the crash only occurs when ROCm tries to convert the uint64_t variable into a string:
| Code: |
(gdb) frame 5
#5 rocr::AMD::GpuAgent::GetInfo (this=<optimized out>, attribute=<optimized out>, value=<optimized out>)

(gdb) p uuid_value
$1 = [RETRACTED]
|
This doesn't make any sense. The function std::setfill() is part of libstdc++, given the correct input, there's no reason for it to crash - I don't see anything incorrect here. I extracted the code to create a standalone test program. It runs correctly without crashing.
| Code: |
user@gentoo /tmp $ cat uuid.cpp
#include <cstdio>
#include <sstream>
#include <iomanip>
int main(void)
{
std::uint64_t uuid_value = 42;
std::stringstream ss;
ss << "GPU-" << std::setfill('0') << std::setw(sizeof(uint64_t) * 2) << std::hex
<< uuid_value;
auto ss_str = ss.str();
printf("%s\n", ss_str.c_str());
return 0;
}
user@gentoo /tmp $ g++ uuid.cpp -o uuid -O3 -Wall -Wextra
user@gentoo /tmp $ ./uuid
GPU-000000000000002a

Although there should no reason for it to crash, for further troubleshooting I disabled this code path in ROCr anyway using the following patch:
| Code: |

Unfortunately, re-running FAHClient, it now crashes at a different place.
| Code: |

|
The offending code rocm/rocdevice.cpp:1356 also makes use of std::stringstream...
| Code: |
1355 std::stringstream ss;
1356 ss << AMD_BUILD_STRING " (HSA" << major << "." << minor << "," << (settings().useLightning_ ? "LC" : "HSAIL");
1357 ss << ")";
|
So basically, the problem here is that when running Folding@Home, libstdc++ crashes immediately whenever std::stringstream is used by ROCm/ROCr/HSA.
The GCC C++ standard library is not going to just crash, especially in its heavily-used I/O subsystem. I'm running out of idea on identifying the root cause...
My best guesses are, it's either
1. a library conflict - given that FAHClient is distributed as a proprietary binary program, perhaps there's ABI incompatibility due to mixing different library/compiler versions between the upstream binary build and Gentoo. I already recompiled ROCm/HSA using GCC 12 instead of GCC 13 (I saw a mix of GCC 12/GCC 13 usage in libstdc++) but without success.
Or
2. Memory corruption. Perhaps a bug in FAHClient or ROCm already corrupted some critical data structure in memory earlier, so later uses of std::stringstream mysteriously fail.
Has any expert out there seen anything similar?

Check what AMD says can be expected to work on your GPU. It appears to be a moving target.

| Whether or not OP's GPU is supported, I agree with the original premise (from back in July) that it is not reasonable for libstdc++ to just crash here. As OP also notes, a test program does not crash, so it seems like an incompatibility. If memory corruption is at fault, running under Valgrind should report something. |

I agree, Hu. However if the GPU is not supported it's entirely possible that it's corrupting memory in its failed attempt to operate. Clearly OP is way beyond me in what he's doing. Part of my reaction here was outrage upon just finding how what the state of ROCm and hardware support looks like.

The GPU is supported by both his current version through to the latest release (6.0.2)
I might build a chart of gfx[xxxx] and at what version support for them starts/ends, checking all the release notes for compatibility is a chore. |

I would really like to see such a chart. I've also found some patches for adding Navi14 support, but haven't done anything about it yet.
I'm also wondering if we should be keeping back-level ROCm stuff in portage simply because it seems so hardware-dependent. Better packaging from AMD would be nice. I was looking at Cuda a bit, and there seems to be one package, but there are various levels of Cuda API support based on the hardware.
