<ASamir> heller: So what should I do if I want to track the tx and rx cqs? Should I read both cqs or there is another way?

<heller___> ASamir: yes, you need to read both
<ASamir> and what should I pass to fi_cq_read if I want to poll all the completions happened? I do not know their number
rtohid has joined #ste||ar
galabc has joined #ste||ar
<heller___> ASamir: just poll for one completion as a start
<heller___> it will return the number of completions, an error code or zero
<ASamir> and then I pass it a pointer to entry structs to get the entries?
<heller___> yes
<galabc> Hi I'm trying to run a hpx executable with different numbers of threads
<galabc> But I always get 4 threads
<K-ballo> how are you asking?
<galabc> srun -p beowulf -N 8 ./data Matrix_Matrix_Mult 100 -- -threads 8
<galabc> Matrix_Matrix_Mult and 100 are parameters in argc
<galabc> srun -p beowulf -N 8 ./data Matrix_Matrix_Mult 100 -- -t 8
<galabc> I keep getting 4 treads
<heller___> how do you know?
<heller___> in addition, IIRC, the beowulf nodes only have 4 cores
<galabc> I use the function hpx::get_os_thread_count()
<galabc> and I always outputs 4
<galabc> But can't I have more threads than core?

<nikunj> hkaiser: yt?
<hkaiser> nikunj: here
<nikunj> hkaiser: so I was able to run global objects on HPX threads as well
<hkaiser> nikunj: yah, I saw your message
<hkaiser> great!
<nikunj> the example run without errors. But I would require a bigger example to run this time
<nikunj> just to make sure everything is working
<nikunj> Do we an example that has many of the HPX functionality?
<hkaiser> I'd suggest running the tests that include hpx_main.hpp
<hkaiser> (and examples)
<nikunj> That was my initially, but my current implementation requires adding multiple c++ flags
<nikunj> So that would mean that I would have to reconfigure the cmake
<hkaiser> ok, so what?
<hkaiser> sure
<nikunj> Then I'll work on it
<nikunj> If everything works fine, I'll send a pr
<hkaiser> k
