Introduction to supercomputing

• Russian-Chinese School on Mathematical Modeling and Parallel Computing: September 22-25, 2020
• Slides and recorded lectures

Practice on linear algebra and parallel efficiency (OpenMP and MPI)

• ssh hpc19@dodo.inm.ras.ru - login to INM RAS cluster (from your local computer)
• xsetup nickname - user setup (from host h2)
• xqs - request the computing resources (from host h2)
• xlist - list the parallel tests available (from h2 or nodes)
• xrun test - run parallel test (from nodes)
• xplot - construct the *.png plots (from host h2)
• http://cluster2.inm.ras.ru/~hpc19/nickname/*.png - view parallel run results on a local browser for a local user
• http://cluster2.inm.ras.ru/~hpc19/sources/*.c - view test sources
• xinfo - this help info (from h2 or nodes)
Some additional commands:
• xget test - get test source (from h2 or nodes)
• xcc test - compile the local test source (from h2)
• xrun - run the local parallel test (from nodes)

Applied statistics practice (use R)

• ssh hpc19@dodo.inm.ras.ru - login to INM RAS cluster (from your local computer)
• xsetup nickname - user setup (from host h2)
• xqs - request the computing resources (from host h2)
• type R and then click "Enter" - run R (from nodes)
• http://cluster2.inm.ras.ru/~hpc19/nickname/Rplots.pdf - check R plots in a local browser for a local user
• xstat - this help info on statistics commands (from h2 or nodes)
