manually started server on each machine. But encountered the following error. terminate called after throwing an instance of 'std::runtime_error' what(): Failed to launch kernel. Error: Failed to execute the kernel...

hi @1tnguyen well, when i used multi nodes for statevector simulation, should i manually start the server? this is right documentation for it? ``` cudaq_location=`python3 -m pip show cudaq |...

Hi @1tnguyen Thanks for your kind reply. i really appreciate your help. I see the cudaq docs and it suggests openmpi instead of MPICH2. I wonder cudaq is compatible with...

Thanks for your reply. i installed mpich with pip instead of openmpi. i have the code that works well with mgpu in one node but if i replace openmpi with...

@ymagchi Thanks. actually, i have used for mgpu simulation of statevector and i noticed the above examples are using cuQuantum. what is the difference between cudaq and cuquantum, 😁? could...

hi @ymagchi Thanks for your kind reply. i followed your guide but it seems like cudaq doesn't provide the multi node simulation for large qubit statevector. i want to simulate...

Thanks, @ymagchi actually, i successfully launched the code on multi nodes but it takes very long time and even 2 hours later, it didn't finish. the gpt said that is...

Thanks very much, @ymagchi i have one more question. i saw one issue mentioned the high qubit circuit sampling or simulation but what is the limit qubit number for cu-quantum?

Hi, @ymagchi Thanks for your support. i tested cudaq to simulate the statevector but i found its index distribution is not correct in the case of high qubit circuit. so...

yes, i installed cuda-aware MPI and confirmed statevector are distributed on each gpu by checking the usage of gpu. but the python file stopped when applying gates operation. i can...
