2 This file defines an "generalized" additive Schwarz preconditioner for any Mat implementation.
3 In this version each processor may intersect multiple subdomains and any subdomain may
4 intersect multiple processors. Intersections of subdomains with processors are called *local
5 subdomains*.
6
7 N - total number of distinct global subdomains (set explicitly in PCGASMSetTotalSubdomains() or implicitly PCGASMSetSubdomains() and then calculated in PCSetUp_GASM())
8 n - actual number of local subdomains on this processor (set in PCGASMSetSubdomains() or calculated in PCGASMSetTotalSubdomains())
9 nmax - maximum number of local subdomains per processor (calculated in PCSetUp_GASM())

1040 PCGASMSetSubdomains - Sets the subdomains for this processor
1041 for the additive Schwarz preconditioner.
1042
1043 Collective on pc
1044
1045 Input Parameters:
1046+ pc - the preconditioner object
1047. n - the number of subdomains for this processor
1048. iis - the index sets that define the inner subdomains (or NULL for PETSc to determine subdomains)
1049- ois - the index sets that define the outer subdomains (or NULL to use the same as iis, or to construct by expanding iis by the requested overlap)
1050
1051 Notes:
1052 The IS indices use the parallel, global numbering of the vector entries.
1053 Inner subdomains are those where the correction is applied.
1054 Outer subdomains are those where the residual necessary to obtain the
1055 corrections is obtained (see PCGASMType for the use of inner/outer subdomains).
1056 Both inner and outer subdomains can extend over several processors.
1057 This processor's portion of a subdomain is known as a local subdomain.
1058
1059 Inner subdomains can not overlap with each other, do not have any entities from remote processors,
1060 and have to cover the entire local subdomain owned by the current processor. The index sets on each
1061 process should be ordered such that the ith local subdomain is connected to the ith remote subdomain
1062 on another MPI process.
1063
1064 By default the GASM preconditioner uses 1 (local) subdomain per processor.

1086 PCGASMSetOverlap - Sets the overlap between a pair of subdomains for the
1087 additive Schwarz preconditioner. Either all or no processors in the
1088 pc communicator must call this routine.
1089
1090 Logically Collective on pc
1091
1092 Input Parameters:
1093+ pc - the preconditioner context
1094- ovl - the amount of overlap between subdomains (ovl >= 0, default value = 0)
1095
1096 Options Database Key:
1097. -pc_gasm_overlap <overlap> - Sets overlap
1098
1099 Notes:
1100 By default the GASM preconditioner uses 1 subdomain per processor. To use
1101 multiple subdomain per perocessor or "straddling" subdomains that intersect
1102 multiple processors use PCGASMSetSubdomains() (or option -pc_gasm_total_subdomains <n>).
1103
1104 The overlap defaults to 0, so if one desires that no additional
1105 overlap be computed beyond what may have been set with a call to
1106 PCGASMSetSubdomains(), then ovl must be set to be 0. In particular, if one does
1107 not explicitly set the subdomains in application code, then all overlap would be computed
1108 internally by PETSc, and using an overlap of 0 would result in an GASM
1109 variant that is equivalent to the block Jacobi preconditioner.
1110
1111 Note that one can define initial index sets with any overlap via
1112 PCGASMSetSubdomains(); the routine PCGASMSetOverlap() merely allows
1113 PETSc to extend that overlap further, if desired.

1197 Collective on PC iff first_local is requested
1198
1199 Input Parameter:
1200. pc - the preconditioner context
1201
1202 Output Parameters:
1203+ n_local - the number of blocks on this processor or NULL
1204. first_local - the global number of the first block on this processor or NULL,
1205 all processors must request or all must pass NULL
1206- ksp - the array of KSP contexts
1207
1208 Note:
1209 After PCGASMGetSubKSP() the array of KSPes is not to be freed
1210
1211 Currently for some matrix implementations only 1 block per processor
1212 is supported.

1232/*MC
1233 PCGASM - Use the (restricted) additive Schwarz method, each block is (approximately) solved with
1234 its own KSP object.
1235
1236 Options Database Keys:
1237+ -pc_gasm_total_subdomains <n> - Sets total number of local subdomains to be distributed among processors
1238. -pc_gasm_view_subdomains - activates the printing of subdomain indices in PCView(), -ksp_view or -snes_view
1239. -pc_gasm_print_subdomains - activates the printing of subdomain indices in PCSetUp()
1240. -pc_gasm_overlap <ovl> - Sets overlap by which to (automatically) extend local subdomains
1241- -pc_gasm_type [basic,restrict,interpolate,none] - Sets GASM type
1242
1243 IMPORTANT: If you run with, for example, 3 blocks on 1 processor or 3 blocks on 3 processors you
1244 will get a different convergence rate due to the default option of -pc_gasm_type restrict. Use
1245 -pc_gasm_type basic to use the standard GASM.
1246
1247 Notes:
1248 Blocks can be shared by multiple processes.
1249
1250 To set options on the solvers for each block append -sub_ to all the KSP, and PC
1251 options database keys. For example, -sub_pc_type ilu -sub_pc_factor_levels 1 -sub_ksp_type preonly
1252
1253 To set the options on the solvers separate for each block call PCGASMGetSubKSP()
1254 and set the options directly on the resulting KSP object (you can access its PC
1255 with KSPGetPC())

1485 PCGASMCreateSubdomains - Creates n index sets defining n nonoverlapping subdomains for the additive
1486 Schwarz preconditioner for a any problem based on its matrix.
1487
1488 Collective
1489
1490 Input Parameters:
1491+ A - The global matrix operator
1492- N - the number of global subdomains requested
1493
1494 Output Parameters:
1495+ n - the number of subdomains created on this processor
1496- iis - the array of index sets defining the local inner subdomains (on which the correction is applied)
1497
1498 Level: advanced
1499
1500 Note: When N >= A's communicator size, each subdomain is local -- contained within a single processor.
1501 When N < size, the subdomains are 'straddling' (processor boundaries) and are no longer local.
1502 The resulting subdomains can be use in PCGASMSetSubdomains(pc,n,iss,NULL). The overlapping
1503 outer subdomains will be automatically generated from these according to the requested amount of
1504 overlap; this is currently supported only with local subdomains.

1544 this is merely a convenience subroutine that walks each list,

1891 Notes:
1892 PCGASMSetSubdomains(), PCGASMSetTotalSubdomains() or PCGASMSetOverlap() take precedence over PCGASMSetUseDMSubdomains(),
1893 so setting PCGASMSetSubdomains() with nontrivial subdomain ISs or any of PCGASMSetTotalSubdomains() and PCGASMSetOverlap()
1894 automatically turns the latter off.
