* Revert "the reseed was wrong"

This reverts commit 3440a07dff3f40e8a8d156ca3f1938558a59249f.

* cast lr in onecycle

* support fp16

* cut off kernel if expand after reduce

* test polynomial lr

* move polynomiallr to examples/mlperf

* working PolynomialDecayWithWarmup + tests.......

add lars_util.py, oops

* keep lars_util.py as intact as possible, simplify our interface

* no more half

* polylr and lars were merged

* undo search change

* override Linear init

* remove half stuff from model_train

* update scheduler init with new args

* don't divide by input mean

* mistake in resnet.py

* restore whitespace in resnet.py

* add test_data_parallel_resnet_train_step

* move initializers out of resnet.py

* unused imports

* log_softmax to model output in test to fix precision flakiness

* log_softmax to model output in test to fix precision flakiness

* oops, don't realize here

* is None

* realize initializations in order for determinism

* BENCHMARK flag for number of steps

* add resnet to bechmark.yml

* return instead of break

* missing return

* cpu_count, rearrange benchmark.yml

* unused variable

* disable tqdm if BENCHMARK

* getenv WARMUP_EPOCHS

* unlink disktensor shm file if exists

* terminate instead of join

* properly shut down queues

* use hip in benchmark for now

linearizer ast as a tuple of lazyops (#3689)
* multi store op linearizer

* currently we do only one output per kernel

* named opts

update kernel dataset to exclude the disktensor ones (#3651)
disk tensor load contains big offset and is not meant to be run by gpu.

repro steps
```
time ./extra/optimization/generate_dataset.sh
gzip /tmp/sops
mv /tmp/sops.gz extra/datasets/
