Version: OpenSM 3.3.x

Repo:    git://github.com/linux-rdma/opensm

Date:    April 2019

1 Overview

----------

This document describes the contents of the OpenSM 3.3 release.

OpenSM is an InfiniBand compliant Subnet Manager and Administration,

and runs on top of OpenIB. The OpenSM version for this release

is opensm-3.3.23.

This document includes the following sections:

1 This Overview section (describing new features and software

  dependencies)

2 Known Issues And Limitations

3 Unsupported IB compliance statements

4 Bug Fixes

5 Main Verification Flows

6 Qualified Software Stacks and Devices

1.1 Major New Features

* Support for HDR link speed and 2x link width

  IBTA has recently (beyond IBA 1.3) added support for HDR link speed

  and 2x link width.

* Nue routing algorithm.

  The Nue routing is a novel topology-agnostic routing approach which

  implicitly avoids deadlocks during the path calculation instead of

  solving both problems separately. Nue routing heuristically optimizes

  the load balancing, i.e., the number of routes per link, while

  enforcing deadlock-freedom without exceeding a given number of

  virtual lanes (VLs). Our Nue implementation for the InfiniBand subnet

  manager supports any number of virtual lanes.

* Support for ignoring throttled links with DFSSSP.

  Throttled links, either because they are faulty or throttled intentionally,

  aren't good for the achievable performance of an HPC system.

  During the discovery process, (DF)SSSP analyzes the theoretical maximum

  enabled link speed, which both ends of a peer link support and compares it

  to the actual link speed. If these numbers don't match, then the link is

  ignored as potential path for routes between nodes. A similar comparison

  is done for link width.

* Support for long transaction timeout for SM class transactions.

  Currently, it is only used for optimized SL2VLMappingTable operations.

  Option is long_transaction_timeout with default of 500 msec.

* Mesh Analysis for LASH routing algorithm.

  The performance of LASH can be improved by preconditioning the mesh in

  cases where there are multiple links connecting switches and also in

  cases where the switches are not cabled consistently.

  Activated with --do_mesh_analysis command line and config file option.

* Reloadable OpenSM configuration (preliminary implementation)

  It is possible now to reload OpenSM configuration parameters on the

  fly without restarting.

* Routing paths sorted balancing (for UpDown and MinHops)

  This sorts the port order in which routing paths balancing is performed

  by OpenSM. Helps to improve performance dramatically (40-50%) for most

  popular application communication patterns.

  To overwrite this behavior use --guid_routing_order_file command line

  option.

* Weighted Lid Matrices calculation (for UpDown, MinHop and DOR).

  This low level routing fine-tuning feature provides the means to

  define a weighting factor per port for customizing the least weight

  hops for the routing. Custom weights are provided using file specified

  with '--hop_weights_file' command line option.

* I/O nodes connectivity (for FatTree).

  This provides possibility to define the set of I/O nodes for the

  Fat-Tree routing algorithm. I/O nodes are non-CN nodes allowed to use

  up to N (specified using --max_reverse_hops) switches the wrong way

  around to improve connectivity. I/O nodes list is provided using file

  and --io_guid_file command line option.

* MGID to MLID compression - infrastructure for many MGIDs to single MLID

  compression. This becomes helpful when number of multicast groups

  exceeds subnet's MLID routing capability (normally 1024 groups). In such

  cases many multicast groups (MGID) can be routed using same MLID value.

* Torus-2QoS unicast routing algorithm - a DOR-based routing algorithm

  specialized for 2D/3D torus topologies. Torus-2QoS provides deadlock-free

  routing while supporting two quality of service (QoS) levels. In addition

  it is able to route around multiple failed fabric links or a single failed

  fabric switch without introducing deadlocks, and without changing path SL

  values granted before the failure.

* DNUP Unicast routing algorithm - similar to UPDN but allows routing in

  fabrics which have some CA nodes attached closer to the roots than some

  switch nodes.

* SSSP Unicast routing algorithm - SSSP unicast routing algorithm - a

  single-source-shortest-path routing algorithm, which globally balances the

  number of routes per link to optimize link utilization. This routing

  algorithm has no restrictions in terms of the underlying topology.

* DFSSSP unicast routing algorithm - a deadlock-free single-source-

  shortest-path routing, which uses the SSSP algorithm as the base to optimize

  link utilization and uses Infiniband virtual lanes (SL) to provide deadlock-

  freedom.

* SRIOV (Alias GUID) Support - In order to support virtualized environments,

  alias GUID support is added to OpenSM. This support allows an SA client to

  add and remove additional port GUIDs based on SubAdmSet/SubAdmDelete of

  GUIDInfoRecord.

* Extended speed support

  This provides support for FDR and EDR speeds.

* Congestion control support (experimental)

* Many code improvements, optimizations and cleanups.

* Windows support (early stage).

1.4 Software Dependencies

OpenSM depends on the installation of libibumad package (distributed as

part of OFA IB management together with OpenSM) and IB stack presence,

in particular libibumad uses user_mad kernel interface ('ib_umad' kernel

module). The qualified driver versions are provided in Table 2,

"Qualified IB Stacks".

Also, building of QoS manager policy file parser requires flex, and either

bison or byacc installed.

1.5 Supported Devices Firmware

The main task of OpenSM is to initialize InfiniBand devices. The

qualified devices and their corresponding firmware versions

are listed in Table 3.

2 Known Issues And Limitations

------------------------------

* No Service / Key associations:

  There is no way to manage Service access by Keys.

* No SM to SM SMDB synchronization:

  Puts the burden of re-registering services, multicast groups, and

  inform-info on the client application (or IB access layer core).

3 Unsupported IB Compliance Statements

--------------------------------------

The following section lists all the IB compliance statements which

OpenSM does not support. Please refer to the IB specification for detailed

information regarding each compliance statement.

* C14-22 (Authentication):

  M_Key M_KeyProtectBits and M_KeyLeasePeriod shall be set in one

  SubnSet method. As a work-around, an OpenSM option is provided for

  defining the protect bits.

* C14-67 (Authentication):

  On SubnGet(SMInfo) and SubnSet(SMInfo) - if M_Key is not zero then

  the SM shall generate a SubnGetResp if the M_Key matches, or

  silently drop the packet if M_Key does not match.

* C15-0.1.23.4 (Authentication):

  InformInfoRecords shall always be provided with the QPN set to 0,

  except for the case of a trusted request, in which case the actual

  subscriber QPN shall be returned.

* o13-17.1.2 (Event-FWD):

  If no permission to forward, the subscription should be removed and

  no further forwarding should occur.

* C14-44 (Initialization):

  If the SM discovers that it is missing an M_Key to update CA/RT/SW,

  it should notify the higher level.

* C14-62.1.1.12 (Initialization):

  PortInfo:M_Key - Set the M_Key to a node based random value.

* C14-62.1.1.13 (Initialization):

  PortInfo:M_KeyProtectBits - set according to an optional policy.

* C14-62.1.1.24 (Initialization):

  SwitchInfo:DefaultPort - should be configured for random FDB.

* C14-62.1.1.32 (Initialization):

  RandomForwardingTable should be configured.

* o15-0.1.12 (Multicast):

  If the JoinState is SendOnlyNonMember = 1 (only), then the endport

  should join as sender only.

* o15-0.1.8 (Multicast):

  If a request for creating an MCG with fields that cannot be met,

  return ERR_REQ_INVALID (currently ignores SL and FlowLabelTClass).

* C15-0.1.8.6 (SA-Query):

  Respond to SubnAdmGetTraceTable - this is an optional attribute.

* C15-0.1.13 Services:

  Reject ServiceRecord create, modify or delete if the given

  ServiceP_Key does not match the one included in the ServiceGID port

  and the port that sent the request.

* C15-0.1.14 (Services):

  Provide means to associate service name and ServiceKeys.
