Middle East Technical University High Performance Computing Usage <\/strong><\/p>\n\n\n\n

Survey Report \u2013 2021<\/strong><\/p>\n\n\n\n

This survey and the report are prepared to understand the current state of High Performance Computing (HPC) usage at the Middle East Technical University (METU). There were 39<\/strong> researchers who responded to the survey in Spring 2021. As seen in Figure 1,  HPC users are affiliated with a diverse number of departments. The largest share of HPC users among the respondents are in Computer Engineering (17.9%) and Aerospace Engineering (15.4%) Departments.   <\/p>\n\n\n\n

In another question, the participants were asked whether they are currently using ULAKB\u0130M-TRUBA HPC resources or not.  As seen in Figure 2, most of the respondents are currently TRUBA users (66.7%). <\/p>\n\n\n\n

As seen in Figure 3, most respondents (51.7%) are using HPC services for running commercial or open-source software while 29.3% and 6.9% developing code specifically for HPC systems and doing research on HPC system architectures, respectively and 3.4% indicated that they do not use HPC services. As seen in Figure 4, HPC systems being used are mainly located in centers in Turkey (42.6%) or owned by their research group (41.2%) and 13.2% reported they use HPC centers abroad. <\/p>\n\n\n\n

Figure 5. CPU and GPU usage patterns<\/p>\n\n\n\n

Typical usage patterns of CPUs and GPUs are given in Figure 5. As seen in Figure 5(a), 71.8% uses between 1-128 processors and only 7.7% uses more than 512 processors. As seen in Figure 5(b), while 30.8% require at most 10K, 30.8% require 10K to 100K cpu-hours. 10.3% do not use any CPUs at all.  As seen in Figure 5(c), 38.5% uses 1-4 GPU cards and 30.8% do not use any GPU cards at all. 25.6% and 15.4% require 10K to 100K and more than 500K gpu-hours, respectively.   <\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

Figure 6. Job length <\/p>\n\n\n\n

As shown in Figure 6, typical jobs require days (53.8%), hours (17.9%), weeks (17.9%) and months (10.3%).  <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Figure 7. Research areas <\/p>\n\n\n\n

Respondents represent a diverse number of research areas (Figure 7). The largest number of researchers are working on Computer Vision (10.9%), Computational Fluid Dynamics (10.9%), Deep Learning (9.1%) and Machine Learning (7.3%).  <\/p>\n\n\n\n

Figure 8. Preferences for high priority on TRUBA systems. <\/p>\n\n\n\n

The last question was \u201cIn case there was a mechanism for higher priority usage what would be the preferences of the users\u201d. As seen in Figure 8, most users prefer either large number of gpu-hours (22.7%) or cpu-hours (20.6%), followed by long running times (18.6%), large number of CPUs (11.3%), large number of GPUs (9.3%). Only 4.1% of the respondents indicated that the ease of application is important. 12.4% indicated that they would apply under any condition.\u00a0<\/p>\n\n\n\n
