RDMA with multiple read/write

Hi, I would like to perform test about RDMA server/client about multiple reads or/and writes. Can server/client store few memory regions? If yes, how? Client writes on different MRs with only one send WR. Is that possible? The goal is: build an array of addresses (MRs) and write (or read) with a

RE: RDMA with multiple read/write

I would like to perform test about RDMA server/client about multiple reads or/and writes. Can server/client store few memory regions? If yes, how? An app can register multiple memory regions. Just call register mr for each region that you want to register. Client writes on different MRs

[PATCH 01/13] Revert opensm: Do not require -Q option for torus-2QoS routing engine.

This reverts commit b9691580e29c6a8cf1f45995988350c02826786d. Since all other routing engines require -Q to cause SL2VL maps to be programmed, torus-2QoS should do the same. Of course, torus-2QoS requires SL2VL maps to be programmed for correct routing, so a check for that will need to be added.

[PATCH 02/13] opensm: torus-2QoS requires that QoS be enabled.

SL2VL maps are only programmed if QoS is enabled. Require this to be the case if torus-2QoS is configured, and print a message otherwise. Signed-off-by: Jim Schutt jasc...@sandia.gov --- opensm/opensm/osm_torus.c |8 1 files changed, 8 insertions(+), 0 deletions(-) diff --git

[PATCH 04/13] opensm: Fill in default QoS values at last possible moment.

The comments for struct osm_qos_options in osm_subnet.h describe values that flag default QoS values for struct members. osm_qos_options structs are initialized with these flag values in subn_init_qos_options(), but they are overwritten via osm_subn_verify_config() with the actual default values.

Torus-2QoS needs 8 VLs, and complete control over sl2vl maps, in order to provide 2 QoS levels with routing that is free of credit loops on torus fabrics. Warn to this effect if an insufficient max_vls configuration or a non-default qos_sl2vl configuration is detected. Also, torus-2QoS needs to
