I notice that our help message for the btl_openib_flags MCA parameter
seems to be a bit out of date:
CHECK(reg_int("flags", "BTL flags, added together: SEND=1, PUT=2,
GET=4 "
"(cannot be 0)",
MCA_BTL_FLAGS_RDMA | MCA_BTL_FLAGS_NEED_ACK |
MCA_BTL_FLAGS_NEED_CSUM, &ival, REGINT_GE_ZERO));
mca_btl_openib_module.super.btl_flags = (uint32_t) ival;
Specifically, we only list values of 1, 2, and 4. But the default
value is 54. So clearly, there's quite a few more flags that can be
set there.
What are they?
