OpenMP: omp_get_max_teams, omp_set_num_teams, and omp_{gs}et_teams_thread_limit on offload devices
This patch adds support for omp_get_max_teams, omp_set_num_teams, and
omp_{gs}et_teams_thread_limit on offload devices. That includes the usage of
device-specific ICV values (specified as environment variables or changed on a
device). In order to reuse device-specific ICV values, a copy back mechanism is
implemented that copies ICV values back from device to the host.
Additionally, a limitation of the number of teams on gcn offload devices is
implemented. The number of teams is limited by twice the number of compute
units (one team is executed on one compute unit). This avoids queueing
unnessecary many teams and a corresponding allocation of large amounts of
memory. Without that limitation the memory allocation for a large number of
user-specified teams can result in an "memory access fault".
A limitation of the number of teams is already also implemented for nvptx
devices (see nvptx_adjust_launch_bounds in libgomp/plugin/plugin-nvptx.c).
gcc/ChangeLog:
* gimplify.cc (optimize_target_teams): Set initial num_teams_upper
to "-2" instead of "1" for non-existing num_teams clause in order to
disambiguate from the case of an existing num_teams clause with value 1.

OpenMP, libgomp: Environment variable syntax extension
This patch considers the environment variable syntax extension for device-specific variants of environment variables from OpenMP 5.1 (see OpenMP 5.1 specification, p. 75 and p. 639). An environment variable (e.g. OMP_NUM_TEAMS) can have different suffixes: _DEV (e.g. OMP_NUM_TEAMS_DEV): affects all devices but not the host. _DEV_<device> (e.g. OMP_NUM_TEAMS_DEV_42): affects only device with number <device>. no suffix (e.g. OMP_NUM_TEAMS): affects only the host. In future OpenMP versions also suffix _ALL will be introduced (see discussion https://github.com/OpenMP/spec/issues/3179). This is also considered in this patch: _ALL (e.g. OMP_NUM_TEAMS_ALL): affects all devices and the host. The precedence is as follows (descending). For the host: 1. no suffix 2. _ALL For devices: 1. _DEV_<device> 2. _DEV 3. _ALL That means, _DEV_<device> is used whenever available. Otherwise _DEV is used if available, and at last _ALL. If there is no value for any of the variable variants, default values are used as already implemented before. This patch concerns parsing (a), storing (b), output (c) and transmission to the device (d): (a) The actual number of devices and the numbering are not known when parsing the environment variables. Thus all environment variables are iterated and searched for device-specific ones. (b) Only configured device-specific variables are stored. Thus, a linked list is used. (c) The output is done in omp_display_env (see specification p. 468f). Global ICVs are tagged with [all], see https://github.com/OpenMP/spec/issues/3179. ICVs which are not global but aren't handled device-specific yet are tagged with [host]. omp_display_env outputs the initial values of the ICVs. That is why a dedicated data structure is introduced for the inital values only (gomp_initial_icv_list). (d) Device-specific ICVs are transmitted to the device via GOMP_ADDITIONAL_ICVS. libgomp/ChangeLog: * config/gcn/icv-device.c (omp_get_default_device): Return device- specific ICV. (omp_get_max_teams): Added for GCN devices. (omp_set_num_teams): Likewise. (ialias): Likewise. * config/nvptx/icv-device.c (omp_get_default_device): Return device- specific ICV.

openmp: Add omp_set_num_teams, omp_get_max_teams, omp_[gs]et_teams_thread_limit
OpenMP 5.1 adds env vars and functions to set and query new ICVs used
as fallback if thread_limit or num_teams clauses aren't specified on
teams construct.
The following patch implements those, though further work will be needed:
1) OpenMP 5.1 also changed the num_teams clause, so that it can specify
both lower and upper limit for how many teams should be created and
changed the meaning when only one expression is provided, instead of
num_teams(expr) in 5.0 meaning num_teams(1:expr) in 5.1, it now means
num_teams(expr:expr), i.e. while previously we could create 1 to expr
teams, in 5.1 we have some low limit by default equal to the single
expression provided and may not create fewer teams.
For host teams (which we don't currently implement efficiently for
NUMA hosts) we trivially satisfy it now by always honoring what the
user asked for, but for the offloading teams I think we'll need to
rethink the APIs; currently teams construct is just a call that returns
and possibly lowers the number of teams; and whenever possible we try
to evaluate num_teams/thread_limit already on the target construct
and the GOMP_teams call just sets the number of teams to the minimum
of provided and requested teams; for some cases e.g. where target
is not combined with teams and num_teams expression calls some functions
etc., we need to call those functions in the target region and so it is
late to figure number of teams, but also hw could just limit what it
is willing to create; in that case I'm afraid we need to run the target
body multiple times and arrange for omp_get_team_num () returning the
right values
2) we need to finally implement the NUMA handling for GOMP_teams_reg
3) I now realize I haven't added some testcase coverage, will do that
incrementally
4) libgomp.texi needs updates for these new APIs, but also others like
the allocator

openmp: Change omp_get_initial_device () to match OpenMP 5.1 requirements
> Therefore, I think until omp_get_initial_device () value is changed, we The following so far untested patch implements that change. OpenMP 4.5 said for omp_get_initial_device: The value of the device number is implementation defined. If it is between 0 and one less than omp_get_num_devices() then it is valid for use with all device constructs and routines; if it is outside that range, then it is only valid for use with the device memory routines and not in the device clause. and OpenMP 5.0 similarly, but OpenMP 5.1 says: The value of the device number is the value returned by the omp_get_num_devices routine. As the new value is compatible with what has been required earlier, I think we can change it already now. 2020-10-22 Jakub Jelinek <jakub@redhat.com> * icv.c (omp_get_initial_device): Remove including corresponding ialias. * icv-device.c (omp_get_initial_device): New function.

openmp: Add basic library allocator support.
This patch adds very basic allocator support (omp_{init,destroy}_allocator,
omp_{alloc,free}, omp_[sg]et_default_allocator).
The plan is to use memkind (likely dlopened) for high bandwidth memory, but
that part isn't implemented yet, probably mlock for pinned memory and see
what other options there are for other kinds of memory.
For offloading targets, we need to decide if we want to support the
dynamic allocators (and on which targets), or if e.g. all we do is at compile
time replace omp_alloc/omp_free calls with constexpr predefined allocators
with something special.
And allocate directive and allocator/uses_allocators clauses are future work
too.
