Remote worker configuration #12

This release does not support distributed computation. |
|
Hi kmatzen: As mentioned in our FAQ, this release does not have an RPC and distributed implementation available yet: http://tensorflow.org/resources/faq.md#running_a_tensorflow_computation, but we are working on it and hope to make it available when it's ready. As a short-term proxy, you can see the Cifar tutorial for an example of how training and distributing among multiple GPUs works -- http://tensorflow.org/tutorials/deep_cnn/index.md |

On some CI nodes (typically those with higher CPU core counts 128/256), the `//tensorflow/c/eager:c_api_distributed_test_gpu` test fails on an intermitent basis. When it does fail, the failures manifests as segfault at the end of the test, with the stack dump shown at the end of this commit message. The stack dump points the finger to a routine within the MKLDNN implementation. This is further confirmed by the observation that disabling the MKLDNN based Eigen contraction kernels (for ROCm) seems to make the crash go away. related JIRA ticket - https://ontrack-internal.amd.com/browse/SWDEV-313684 A previous commit disabled the `//tensorflow/c/eager:c_api_distributed_test` unit-test only in the CPU unit-tests CI job (for the same reason). That comit cannot be reverted, because this commit disables MKLDNN based Eigen contraction kernels *only* for the ROCm build. ``` Thread 191 "c_api_distribut" received signal SIGSEGV, Segmentation fault.

… to Initialize() Imported from GitHub PR openxla/xla#12228 The first time that a NormThunk is executed, it will build a cudnn execution plan. This build step can hang if a NCCL collective is running at the same time. To fix this, I've moved the build step to take place during thunk initialization. We only observe this hang when using cudnn 9. Here's a backtrace from the hang that will be fixed: ``` Thread 585 (Thread 0x7fb9391ff640 (LWP 41364) "main.py"): #0 0x00007fd3d17cffd9 in ??

… to Initialize() Imported from GitHub PR openxla/xla#12228 The first time that a NormThunk is executed, it will build a cudnn execution plan. This build step can hang if a NCCL collective is running at the same time. To fix this, I've moved the build step to take place during thunk initialization. We only observe this hang when using cudnn 9. Here's a backtrace from the hang that will be fixed: ``` Thread 585 (Thread 0x7fb9391ff640 (LWP 41364) "main.py"): #0 0x00007fd3d17cffd9 in ??

Does this release support remote workers out of the box? I couldn't find details in the tutorials, but the whitepaper and
tensorflow/core/common_runtime/device.htalked about adding remote devices through RPC. Is a parameter server or alternative already implemented in here somewhere? If remote workers are supported out of the box, what is the execution model? Is there a daemon or do you have to configure a session in a certain way to act as one?The text was updated successfully, but these errors were encountered:
