# FEAT: Add std::hash\
## Rationale
It's needed to easily use pmem::obj::concurrent_hash_map with pmem::obj::string as a key.
## API Changes
Add Default implementation of hasher for pmem…

The whole part of pmem is code commented. https://github.com/intel-analytics/analytics-zoo/tree/bigdl-2.0/scala/dllib/src/main/scala/com/intel/analytics/bigdl/dllib/feature/pmem
Need to continue mig…

**What is your proposal**:
On the machine with PMEM hardware, we can utilize this hardware capability, migrating BE pods memory to PMEM instead of evicting them directly when the system archives the …

createStringObjectFromLongLongA - there should be a memkind allocation for embedded string/int

When the process starts, open the file report "an ADR failure was deteched, the pool might be corrupted" through pmemobj_open.
1)What does this error mean?
2) Does it mean that there is data lo…

- 首先查看`os_mem.c`文件,观察有如下7个函数:
## OSMemCreate
```c
OS_MEM *OSMemCreate (void *addr, INT32U nblks, INT32U blksize, INT8U *perr);
```
## OSMemGet
```c
void *OSMemGet (OS_MEM *pmem, I…

Use dm-linear to map two 1 GB PM devices:
```
$ echo -e "0 `sudo blockdev --getsz /dev/pmem0` linear /dev/pmem0 0 "\\n"`sudo blockdev --getsz /dev/pmem0` `sudo blockdev --getsz /dev/pmem1` linear /d…

We use the same configuration to run K-means & SVM algorithm. The cluster contains 3 workers and each contains 1TB PMEM. The performance has 12.9% regression when running SVM 1.2TB scale and 28.6% reg…

The performance data showed below:
Component | Configuration | Status | Succeeded Cases | Failed cases | Baseline time/s | Optimized time/s | Performance gain/%
