Cluster instability
by Juani Bermejo Vega 11 Jul '25

11 Jul '25

Dear quanta, As you have probably seen, thermal instability in the cluster is causing recurrent problems. Jose is pretty overworked with service issues, and we cannot make sure we will keep the HPC services operable in August. We might even have problems in the next weeks. It would be best that we finish simulations for urgent projects in the next two weeks, and we use the holidays to get some rest. I would try to leave the HPC resources during summer for those people that need it more urgently, since Proteus services might not run properly or cease to be operable. I would like to please ask you to get back to me if you need urgent jobs to run, simulations to be finished soon with strict deadlines. There is a number of projects that have imminent deadlines (finishing master theses, some simulations for incoming papers). It would be ideal to send jobs to the cluster only if they really need to be run on a cluster. If you need to finish something urgently, please let us make a list of jobs that need to be run and distribute them as efficiently as possible across the different HPC units we have. Before sending jobs to our super-nodes, we thank you if you can analyze the resources that you need. I have written a short guidelines with tips on how to identify the ideal machine for your simulation (you can also ask me or Jose for help): a) If your code does not use a lot of RAM, does not use multiprocessing / multithreading or parallelization with other techniques, you might get better results running it on a laptop or a workstation. The single-cores in last generation laptops like Apple M2's or M3's or last-generation Ryzens often have faster clock cycles than cluster single-nodes. b) If you use Python on the cluster, please try to compile it and enable multi-threading with Numba or PyOMP (installed in the cluster) ifyour code is mostly Numpy based. Certain Python libraries like PyTorch or Jax have in-built optimization/parallelization options that you can activate. Interpreted Python with no-optimization and no-parallelization gives poor results on the cluster, and it is best to run such programs locally on laptops or workstations. c) If you use C/C++, try using the AMD clang compiler in the cluster instead of regular GCC or G++. It is massively better than GCC/G++ because this compiler is optimized for the AMD EPYC. If your code runs out of memory, you can use options like fast-math to use less floating point precision. If you are using optimization commands like O1, O2, O3, avoid using O3 if your code uses a lot of memory. d) If your code is slow but does not use excessive memory, we typically recommend enabling OpenMP multi-threading to make use of the 96 cores in the EPYC nodes, or enable CUDA-parallelization if you are in the GPU: https://urldefense.com/v3/__https://www.openmp.org/spec-html/5.0/openmpse50… https://urldefense.com/v3/__https://developer.nvidia.com/cuda-zone__;!!D9dN… e) If you enable multithreading, you might have to turn down optimization options (e.g., use O1 instead of O2/O3). Or turn down completely. These options can heat up the cluster f) If you dont have good CUDA parallelization, non-compiled code, you will probably heat up the cluster a lot by sending the code to the GPU A100. g) When sending jobs to a given node, make sure you only reserve the resources you will use (e.g., remember not to book the AMD EPYC in Orion if you only want to use the NVIDIA GPU, another person can use the EPYC while your job runs in the GPU). *Available HPC units:* *Lenovo ThinkStation P3: *For non-optimized code, if you do not need a lot of RAM, or if your code is non-parallelizable, I would like to propose that we try to run such jobs on my *Lenovo ThinkStation P3,* located in my office. Jose and I are going to see if we can configure a smaller simulation server there. This ThinkStation has 32 Gb of RAM DDR5, a 1Tb of hard disk and an nVIDIA® RTX A2000 12GB. It is not comparable to the Proteus Orion nodes, but it is powerful enough to run many simulations that cannot be run on a regular laptop. *AMD EPYC CPUs in Orion nodes: *As a rule of thumb, the AMD EPYC in our oldest orion node with 1,5 Tb of RAM is only needed for simulations with more than 33 pure-state qubits up to 37 pure state qubits.This node is our best call for simulations that require massive amounts of RAM, If you can do your simulation with less than 7500 RAM, it is best that you send the job to our second Orion node, which has another AMD EPYC with half the RAM memory. *NVIDIA A100 GPU:* For simulations between 22 and 33 pure state qubits, the NVIDIA A100, with 80Gb, can sometime handle simulations typically faster than the EPYC nodes. However, my impression is that it can get very warm. I do not recommend using it if your code uses memory below 22 pure state qubits because its latency time will kill any advantage compared to an EPYC. Also, you can probably run such a simulation on a laptop or my ThinkStation. Good examples for the GPU are codes that use massive parallel versions of a small program. Codes that will generate large videos or operate with large data-sets of objects like pictures, or wave-vectors of moderate system sizes. Machine learning algorithms are usually another example. Please, let me know what programs need to be prioritized in the next two weeks. I would like to talk to Jose to see what the current situation of the nodes is and make a sensitive plan for projects with inminent deadlines. Best, Juani

Programa anticipos UGR
by Juani Bermejo Vega 03 Jul '25

03 Jul '25

Dear all, I think that UGR owes money to some of us. Since the admin situation now is a bit irregular, I recommend you to take a look at the programs of UGR Gabinete de Atención Social because there is one to request an advanced payment: https://gas.ugr.es/ayudas/*/view/anticipos I will probably apply because they have not paid me a significant amount of salary complements and they also currently owe me money from trips. For this month there is a deadline until 15th July. Typically you can apply every month until the end of the month. In order to apply to GAS aid, you need to have made the tax declaration of your unidad familiar. It requires a few days to fill in the paperwork. Best, Juani
