Send a matrix as a proc argument in Chapel -


i'm getting error when try send matrix proc. i'm pretty sure i'm doing wrong, can't figure out.

use linearalgebra;     proc main() {   var = matrix(        [0.0, 0.8, 1.1, 0.0, 2.0]       ,[0.8, 0.0, 1.3, 1.0, 0.0]       ,[1.1, 1.3, 0.0, 0.5, 1.7]       ,[0.0, 1.0, 0.5, 0.0, 1.5]       ,[2.0, 0.0, 1.7, 1.5, 0.0]       );    check_dims(a); }  proc check_dims(a: matrix) {    var t: bool  = false;   if (a.domain.dim(1) == a.domain.dim(2)){     t = true;   }   return t; }

gives me

mad.chpl:3: in function 'main': mad.chpl:14: error: unresolved call 'check_dims([domain(2,int(64),false)] real(64))' mad.chpl:17: note: candidates are: check_dims(a: matrix)

i'm using chpl version 1.15.0

linear algebra objects (like matrices , vectors) represented arrays in chapel. therefore, changing matrix (a type not exist) [] (the syntax array-type) should work expected:

use linearalgebra;     proc main() {   var = matrix(        [0.0, 0.8, 1.1, 0.0, 2.0]       ,[0.8, 0.0, 1.3, 1.0, 0.0]       ,[1.1, 1.3, 0.0, 0.5, 1.7]       ,[0.0, 1.0, 0.5, 0.0, 1.5]       ,[2.0, 0.0, 1.7, 1.5, 0.0]       );    check_dims(a); }  proc check_dims(a: []) {    var t: bool  = false;   // method dim()   if (a.domain.dim(1) == a.domain.dim(2)){     t = true;   }   return t; }

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
