Intel® MPI Library Reference Manual for Linux* OS
The Checkpoint-Restart feature in Intel® MPI Library is designed to be application transparent. You can access to the Checkpoint-Restart functionality through the MPI process management interface. The Checkpoint-Restart options and environment variables are applicable to the Hydra process manager only.
Note:
The Checkpoint-Restart feature requires the OFA* network module. You can choose the OFA network module, for example, with the I_MPI_FABRICS environment variable by setting the value to ofa, or the -ib option.
Note:
To enable the Checkpoint-Restart feature, set the following:
1 for I_MPI_OFA_DYNAMIC_QPS environment variable
0 for I_MPI_OFA_NUM_RDMA_CONNECTIONS environment variable
Note:
Install the Berkeley Lab Checkpoint/Restart* (BLCR) Software for the Checkpoint-Restart function.
